'. >> this is ynn news room live from los angeles. sarah ready to stuff the trump. that part of a terrible, horrible, no good very bad day for trump's main rival, ted cruz. and his plan for undocumented workers, he said worked 60 years ago, but experts tell a different story. hello, welcome to our viewers in the united states and all around the world. great to have you with us. i'm john vause. newsroom l.a. starts now.

>> there are reports of gun fire at a university. the school is 150 kilometers from islamabad. three gunmen are said to be hiding in different parts of the university. a journalist on the scene tells cnn a blast was heard near the main gate. as of now, the school's chancellor is telling pakistani media no students have been hurt. but according to geo news, at least five people have been injured and taken to hospital. all of this coming just over a year after the taliban killed 134 students at the school in the city not far from here. we'll have live updates for you as soon as we get them.

>> sarah palin endorsed donald trump for president. it was a raucous, sometimes meandering speech. its lashed out at isis, the establishment republicans and hillary clinton. >> are you ready to make america great again? >> better than anyone, isn't he known for being able to command, fir fire. are you ready for a commander-in-chief? are you ready for a commander-in-chief who will let our warriors do their job and go kick isis' ass? >> for the gop establishment tor koch b donald trump's supporters even for accusations that are so false? they are so busted the way that this thing works. we, you, a diverse, dynamic

needed support base that they would attack. and now some of them even whiserring they're ready to throw in for hillary over trump because they can't afford to see the status quo go. otherwise they won't be able to be slurping off the gravy train that's been feeding them all these years. they don't want that to end. how about the rest of us? right wing and bitter, clinging proud klinglers of our gun, our god and our religions and our constitutions tell us we're not red enough? yeah, coming from the establishment. dog gone we're angry, justifiably so. yes. you know they stomp on our neck and then they tell us just kill. okay? just relax. well, look, we are mad and we've been had. they need to get used to it. this election is more than just your basic abc's, anybody but

clint clinton. it's more than that this go around. you only go to war if you're determined to win the war. and you quit footing the bill for these nations who are oil rich. we're paying for some of their squirmishes that have been going on for centuries, where they're fighting each other and yelling allah akbar and calling jihad on each other. let them duke it out. iowa, you say a lot. being here tonight, supporting the right man who will allow you to make america great again. god bless you, god bless the united states of america and our next president of the united states, donald trump j. trump.

>> that stage almost seemed too small for those two people up there. >> that's the most sarah palin anybody has heard for a long time outside of fox news channel. that's part of the story there. this may be as much about bernishing her image, but for a slice of the republican electorate, she is a validating force. >> okay. it was a good day for donald trump. it was a terrible tuesday. okay, explain to our viewersing exactly why this will have such a big impact on ted cruz? >> he got squeezed today from both sides of iowa. in iowa, donald trump is playing with the house's money. he is ahead in new hampshire. and the republicans have never nominated someone in the modern primary, who did not one one of the two. he's already in a strong position and wins. he puts the rest of the field in a disadvantage. you have sarah palin, reinforcing donald trump on the right to an extent, probably even more significant. you have terry branstead, the

governor, criticizing cruz over his opposition to ethanol subsidies. and that reduces the possibility that more voters in the center, which is a branch that comes from, will view cruz as the lesser of two evils to trump. >> ted cruz tweeted this out, it was actually a bit of damage control, actually. he said i love sarah palin, without her support, i would not be part of the senate regardless of what he dpid in 2016. >> cruz has run a very disciplined campaign over the last couple of months. why wouldn't they have locked up sarah palin before she went over to the trump side? >> well, it might not have seen to be a priority. sarah palin isless of a force than she once was, but that quote, that tweet is actually indicative of the broader cruz strategy where he really has not come back as hard against trump as trump has gone against him. i think cruz may be underestimating the gravity of the situation. only one republican in the

modern primary era has won both iowa and new hampshire, that's gerald ford, a sitting president in a contested race anyway. if trump wins both, that makes it very difficult for everyone else. and cruz really, most people think he's in the driver's seat in iowa but only narrowly, if trump can expand the electorate or cutaway at cruz's support, particularly where each of their support kind of overlaps, cruz could be in a vulnerable position. >> let's take a look at the front page of the new york daily news tomorrow. they're having a bit of fun, if you like, with this teaming up, i'm with stupid. in a general election campaign, an endorsement of sarah palin will be kind of radioactive. this is a primary. again, this begs the questions that the tactics of trump is getting is going to come back and hurt him if he gets the nomination to run in the general. >> pay lip does reflect the same kind of strategy of trump. she is a candidate focused at

what has become the core of the republican base, blue collar, culturally conservative voters who feel the country is being fundamentally transformed and taken away from him. if trump is the nominee, he will test this theory that people like pay lip and sean hannity have been arguing for years, the way for republicans to win is to give those voters the real deal and millions of them will turn out. the problem is in the process, trump is alienating all of the groups at the core of the growing democratic coalition. minorities, millennials, it's hard to believe that you're get a turn out without sparking a counterreaction on the other side. and the other side is now bigger. >> stay with us. there's some interesting poll numbers to talk about on the democratic side. but we will move on because donald trump has been very enthusiastic about the idea of governor palin actually joining a future trump administration. let's listen to this. >> if there is a trump administration, could you see maybe picking up the phone and giving the governor a call,

picking her brain on some things? or perhaps having her along in some official capacity? >> i would love that. she really is somebody that knows what's happening. and she's a special person. she's really a special person. and i think people know that. >> sarah palin has said she would be interested in being energy secretary because she wants to give individual states more control over their oil and gas reserves. but the department of energy does not regulate oil and gas development. that would be the department of the interior. the department of energy overseas the u.s. nuclear weapons program, handles radioactive waste and does energy-related research. the current energy secretary is dr. earnest muniz. he's a nuclear physicist. sarah palin and donald trump have long had what some would call a political love affair. more now on the ties that bind. >> reporter: the political romance between donald trump and

sarah palin began during the campaign of 2008. >> she's made a tremendous impact. the impact that she has had on rejuvenating almost the republican party, it's been unbelievable. >> palin needed that vote of confidence, coming less than three weeks after her announcement as mccain's vp. she was already facing tough questions about her experience. questions that would hit critical mass just a week after trump's praise of palin during this now infamous interview with katie couric. >> what newspapers and magazines diz you regularly read before you were tapped for this to stay informed and to understand -- >> i read most of them, again, with a great appreciation for the press and the media. >> which ones specifically. >> all of them. >> palin did not go on to be vice president and resigned as governor of alaska in 2009. she became a full-time pundit and released two books.

then in 2011 at the height of trump's so-called birther campaign against president obama, the two had a highly publicized pizza date, while palin flirted with her own run for president. >> how about a trump-palin ticket. >> that sounds exciting. >> how does that sound to you, donald? >> sounds very good. >> reporter: palin in return had trump's back on the birther issue. >> i respect what he's doing and putting his money where his mouth is. he's actually investigating his speculation there on obama's birth certificate. >> reporter: fast forward to june 2015. donald trump announces he's running for president and says this -- >> they're bringing drug, they're bringing crime. they're rapist. and some, i assume, are good people. >> it ignited a firestorm. palin defended him on facebook writing, mr. trump should know he's doing something right when the malcontents go ballistic in the press. in july, trump got another taste of presidential campaign

backlash for saying this about senator john mccain. >> he's a hero because he was captured. i like people who weren't captured, i got to tell you. >> reporter: palin called both men heros in an e-mail to cnn writing senator mccain dedicated his life to serving our country, putting it all on the line to defend freedom is heroic. and donald trump is a hero in another arena. in december, another trump firestorm. >> donald j. trump is calling for a total and complete shutdown of muslims entering the united states until our country's represents can figure out what the hell is going. >> and another defense by palin. >> he's talking about a temporary ban. we do have a very screwed up system that is resulting in the bad guys coming on over. >> thank you. >> reporter: and today, the political love affair couldn'ts.

it's anybody's oguess just how far it will go. randi kaye, cnn, new york. >> a new poll shows bernie sanders crushing hillary clinton in new hampshire. senator sanders leads secretary clinton 60% to 33% among likely democratic voters. >> the poll was mostly done, it showed his support has grown by 10% since late last year. >> we'll explain exactly what's happening with these numbers. >> cheerily he's ahead. this poll projects a big turnout in the democratic party among independents who are allowed to vote in new hampshire. that would be high by historic standards.

that would inflate the lead a little bit. having said that, the real significance of this poll for me is the first one i see that shows sanders ahead among self-identified democrats nationally. nbc wall street journal this week saw hillary clinton up 35 points among people who identify as democrats. we talk about the eliminating factors for sanders. in this poll, it shows him breaking past that barrier, and that could be a significant source of concern for the capitol hill ton campaign. >> there's less than two weeks to go. thanks for being with us. . more now on our breaking news out of pakistan. let's go to alexander field who's life at this hour in new dehli. it's been an ongoing situation at a university campus in the northwest part of pakistan.

>> this is a university that's northwest of pashawar. we're told there's a blast near that gate this morning. reporters have heard shots fired from within the university. it's believed that the gunmen remain inside of the university. there are reports that are trickling out that this is one of these situation, joen than, where we need to be incredibly careful to try to understand what exactly the situation is. this is a situation that remains

very active. the security operation continues there right now. we are being told the prime minister is now monitoring the situation, keeping a very close eye on this. of course, trying to ensure that all students, all staff member, all administrators and the security forces who have responded remain safe at this point. there is word from one of the administrators that no students have been hurt. of course, this is something we'll continue to develop over the next few hours. we'll have to watch closely and sort through the various reports over exactly what is going on inside the university. >> alexandra field with the latest there on that ongoing hostage situation at the university in the northwest part of pakistan. thank you. a short break here. an apology from michigan's governor for lead poisoned water. find out what he's promising to do to fix it. also ahead, growing calls for action to end a dangerous gas leak in southern california. cnn goes on a tour of the site. more on that. plaque psoriasis...

>> welcome back, everybody. there are reports in pakistan of

gunfire at a university. a local official tells cnn up to 20 people have been wounded after militants attacked. the prime minister issued a statement saying the school -- apparently the school is about 150 kmom ters outside of islamabad and this is what we know right now. reports say at least three gunmen said to be hiding in different parts of the university. soldiers have entered the school. and a journalist on the scene tells cnn a blast was heard near the main gate. the skoom's chancellor told pakistani media no students have been injuried. we have that report saying up to 20 people have been hurt. so clearly, this is a .developing story. much at this point is unclear. but we do know there has been this attack on this campus on the northwest part of the country.

>> moving on now, the michigan governor rick snyder says he's sorry about the crisis in the city of flint where drinking water is contaminated with lead, and he's promising to fix it. >> your family has faced a crisis, a crisis you did not create and could not have prevented. we want to let you know we are praying for you, we are working hard for you and we are absolutely committed to taking the right steps to effectively solve this crisis.

>> protesters are calling for his resignation. some want him arrested. and the u.s. environmental agency released a statement saying resistance at the state and local levels to work with us in a forthright, transparent and proactive manner are consistent with the seriousness wft risks to public health. the agency goes on to say we much ensure this situation never happens again. another environmental vice scri continues to unfold in porter ranch, california. residents say a massive gas leak is making them sick. >> john, after the tour, congressman sherr pert who lives here in porter ranch said he could not believe how old some of the equipment is here, especially pipeline that's decades old. he also restated he wants the facility shut down after taking that tour. >> we must have been half a mile away and you could hear this loud gushing sound.

it really surprised me how loud it was. there's fluff gas coming out of that every day to fill the empire state building. over the several months, there's been probably 4 billion cubic feet of natural gas escaped from that well. >> we're entering into the last phase. we're down about 8,000 feet. at about 8,500 feet, we will intercept the bad well, and we'll be able to then pump the muds and the liquids in there that will stop the leak. >> i don't believe them. they haven't told us the truth from day one. >> my phone has been ringing literally off the hook every single day with people crying.

they're in fear. they're in fear that they lost everything. they lost their nest egg. they've lost their home, they've lost their sense of community. >> and councilman englander came out and said he thinks between 10,000 and 12,000 people have been displaced by the porter ranch gas leak. he said many of those people are not taking money from socal gas to relocate elsewhere. and he also said this is a community that has many resident dens that have many people living inside, including in laws. >> we'll take a short break here. when we come back, donald trump gets the backing of a politician just as polarizing as he is. and youle' hear about the controversial roots to his immigration plan. also made, the u.s. supreme court takes up a controversial immigration topic planning to answer this question -- did the president misuse his executive power? in new york state, we believe tomorrow starts today.

and bottom line save more money. together, we're building a better california. we're live with breaking news out of pakistan where there's been an attack at a university campus in the northwest of the country. >> we're hearing that two of the attackers have been killed. that information doming from security forces conducting operations on the ground. we're being told that they're now at the campus.

they are also doing air surve surveillan surveillance. so their operations have begun. it is not clear, however, how many attackers could remain inside the campus at this point, security forces do not have that information. the explosions could have something to do with the security operations that are going on. we just cannot sort that out. but we do know that there are thousands of students that attend this university. an administrator said there were 3,000 students there, 600 guests. initial reports said that five people, unidentified people at this point had been injured and taken to hospitals. we're now hearing from authorities on the ground that that number could be closer to 20. on top of that, we're hearing now separately that two attackers may have been killed. but john, this is very early going. these operations are continuing

right now. this is an evolving hostage situation. so it's simply too early to tell who exactly could have been injured, what the extent of the injuries are and if there could be more who would be injured in the coming hours. certainly it is the hope of the security forces that they can put an end to this swiftly and decisively. but again, no word on how many attackers remain at that campus this morning, john. we do know that the prime minister's office is closely monitoring the situation, particularly now that we know that these security operations have begun. >> donald trump picked up a major endorsement for the queen of the tea party.

she praised trump for speaking out on tough issues. >> he's the only one who is willing wear the issues need to be spoken about and debated. they've been wearing political correctness kind of like a suicide vest. >> the rise in the republican field has been a big boost to undocumented workers. his inspiration for that plan goes back more than 60 years. >> president eisenhower, who was a very nice man. i like ike. that was his slogan. my slogan is make america great again. his was i like ike. probably the number is 2.3 million. some say it's 1.5 million, went through this process. >> a lot of people think that's

a shameful chapter in american history. >> some people do, some people think it was a very effective chapter. what happened was when they removed some, meaning brought them back, they removed some. everybody else left. and it was very successful in one sense. so that's the way it is. >> looking at the iedsen hower deportation plan which had the awful name, operation wetback, it's basically the model for the trump policy here. he said it worked back then. what have you found out in terms, i guess, of specifically about the number of undocumented migrants who were actually deported. >> the trick about this operation, which as you said was called operation wetback back in '54 is that it's really almost impossible to verify the number of people who were deported or forced to leave the country in that operation.

there are no good records, and it's also really important to think about the fact that many of these people did come back. he claims that they left and were taken deep into the interior of mexico. but many did come back and it was not a solution to the immigration problems as he claims it was. >> okay. looking forward to mr. trump's plan here. so knowing what we know about how the eisenhower plan did or did not work, what would be the impact, i guess, on the economy if they tried something like this again. and i guess also on families. >> well, it's so fascinating. you wonder sometimes if we're asking the right questions on the campaign trail. you have 5.1 million children

here in america who have at least one undocumented parent. we talked to one professor at the university of texas who talked about that problem and what we would face here in the u.s. >> there are at least 1 million u.s. children with at least one undocumented parent. the vast majority of those are mexican or central american. so 5.1 million children in the united states, which is a significant proportion of the entire child population of the united states would suddenly be made orphans. you could say oh, well, these children don't belong here, but they do belong here. they're u.s. citizens. of. >> what did the trump campaign say? >> soften they're not engaging on poll city details a the all.

>> it's an in depth report. it's on our website. i recommend everyone to have a look at it. it's very interesting reporting. check out the entire piece at cnn.com. thank you. the u.s. supreme court says it will rule on president obama's immigration policies. mr. obama used executive actions more than a year ago to allow some undocumented immigrants to be eligible for work and associated benefits. the high court is likely to rule the case in six or seven months. opponents argue the president abused his power by not going through congress. federal courts in 26 states have already blocked the program, leaving millions of migrants in limbo, terrified of deportation. >> an exclusive look at an army looking to respond to a worst case scenario. also, frustration and high hopes that a u.s. diplomat describes negotiations to free americans held in iran.

>> just coming to more now in pakistan. gunfire and explosions have been heard at the bat university in northern part of the country. news reports say seven have been killed, 20 others have been injured. officials tell us two attackers have been killed by security forces. but at this stage, we do not know how many people carried out this attack at the university. the prime minister of pakistan issued a statement saying he is deeply grieved by this attack. so far, no claims of responsibility. >> now growing fears of a nuclear armed north korea, testing a hydrogen bomb is especially troubling to the 28,000 u.s. troops stationed near the dmz.

paula hancocks met a team to see how they're preparing for the possibility of a nuclear attack. she joins us live now from seoul. paula? >> hello, john. pyongyang is still celebrating its nuclear test. but troops, u.s. and south korean, on this side of the border were on a heightened state of alert immediately afterwards. none more so than the 23rd chemical battalion, the first line of defense for a nuclear or %-p preparing for the fallout of the battle that the world hopes it will never see. >> u.s. troops are on high alert. the 23rd chemical bah tottalion the first line of defense. they're clearing an underground facility used to store nuclear

weapons. the scenario is staged but the threat is very real. >> the beauty of being able to train underground for this battalion is it is far more realistic. north korea's nuclear and chemical facilities are expected to be deep underground. so that they're out of sight of satellites and drones. >> this is the largest chemical battalion in the hole of the u.s. military, based where the threat is greatest. the troops discover yellow cake or uranium, a substance north korea is believed to possess. >> we take into account the newest intelligence to tailor our training to ensure we're ready for anything they could possibly have or use on the battlefield. >> for that bah toll -- battalion to be on the ground. >> it's fairly likely that the mountainous terrain will provide caves and underground facilities for them to be utilizing as weapons facilities. >> the unit operating ahead of the frontline to detect radiation or chemical agents.

field labs can be set up wherever needed. testing samples to create a train of custody that can then be used as evidence for the international criminal court. the university is ready to fight tonight. the u.s. military's answer to the unpredictable threat north of the border. >> these kind of drills and training are ongoing for the 23rd chemical ball ball -- batt. every year without fail, this angers pyongyang, military drills. but the u.s. and south korea also insist they're defensive in nature. john? >> paula, thank you. paula hancocks live in seoul. some americans released by iran over the weekend are speaking out about their experience. so is the u.s. diplomat who negotiated their release. we get details from jim sciutto.

>> jason raizan seen laughing with his wife. >> happy. >> still, the first of the freed americans to speak said their detention ended only after one final night of fear and uncertainty. >> up until the last second, we were all worried and concerned. we were just put in a small room and we had no telephone or access to information. we kept being told we were going to take off in two mourps two became six and ten. so a total of almost 2 1/2 days was really nerve wracking. >> the american diplomat who negotiated the americans' release over 14 months of secret talks told us the first sign of trouble that evening was when we and his team could not locate raizain's wife and mother. >> it was concerning. >> turns out, they were being held in a part of tehran's airport controlled by the military. >> i said no, the entire thing

is off unless they're on the airplane. >> you would have killed the deal if jason's mother and wife were not on that plane. >> it's all part of the deal. so that's part of the deal. period. >> and do you think the iranians at that point were trying to change the terms? what were they trying to do? >> it's unclear. there's a lot of people in the iranian system, and the people who hold the keys to the prison cells, that never wanted this to happen. >> mcgirk was not convinced the deal was back on until the swiss ambassador, america's diplomatic representative in tehran narr e narrated the scene second by second by telephone. >> he was on the tarmac and described a van approaching the airplane. couldn't see in the windows. and the doors opened and one by one he explained it was jason's wife. it was his his mom and wife and

described them getting on the plane. it was the key moment for us. that was the trigger for us. i'm never forget his voice in my ear. mcgirk's public role included only the war on isis showed up at nuclear talks in iran and vienna. >> he did make a lot of progress there. but then when i got back together with my counterpart, they kind of went back to square one. >> i've spoken to diplomats involved with the negotiations who required the urgency, including fears that jason raizain faced the prospect not just of a long prison sentence, but this is alarming, the possibility of a death sentence.

>> iran said it would use its newfound money for what he called nefarious act fifties. >> there's been a lot of response. the position of my government is we will support any deal that prevents iran from acquiring nuclear capability that has a robust and continuous inspection regime and that has operations. we were ensured by the president that this was, in fact, the case and it's a consequence that supported video. the concern we had is what iran will do in terms of additional revenue. it generates as a result of the lifting of some of the sanctions our concern is that that will be used to support terrorism and to spread instability in the region. >> is saudi arabia abandoning the possibility of a nuclear option? >> wolf, i would not discuss

these things in a public forum, certainly not on television. the kingdom of saudi arabia is committed to two things. two things we do not negotiate over, our faith and our security. saudi arabia will do whatever it takes in order to protect our nation and people from any harm. >> saudi arabia says hi country has confidence in washington, but not a lot of confidence in tehran. we're being told that seven b people have been killed. 20 others have been wounded after gunmen stormed the university campus at the northwestern part of the country. this is an ongoing situation with reports that. so soft students may, in fact, be held hostage right now. this is a university that has about 3,000 students enrolled, according to one report. many of the students were in class at the time of the attack. officials also telling cnn, two

of the attackers have been killed after a shootout with security services. there have also been reports of another explosion. this is an ongoing situation unclear of how many gunmen are, in fact, on the grounds of the campus. we will have a live regarding the latest news we have regarding pakistan or new delhi. we were in a german dance group. i wore lederhosen. so i just started poking around on ancestry. then, i decided to have my dna tested through ancestry dna. it turns out i'm scottish. so, i traded in my lederhosen for a kilt.

>> seven people have been killed in pakistan, 20 others wounded after a gunman aing thatted a university near the afghan border. security forces have killed at least two attackers. unclear right now if the seven dead are actually, the number of attackers is included in the seven dead so far. we have two attackers killed. death toll of seven right now. what is the very latest you ear hearing from the scene. >> john, we know that this is an

ongoing operation. it's a very tense situation, which is the city is closed to the main provencial city of northwestern pakistan. we've been getting information from the military that there's an area of surveillance. we are unsure as to how many militants are actually holed up inside the university. we've been told by the vice chancellor that there are at least 3,000 students there. >> it's just a very tense situation and information coming out is very vague right now. >> it's not entirely confirmed who has been killed.

but he used the word guess, but was he referring to an event which was happening on the campus? i was reading that there were hundreds of people who were on the campus for a special event. >> we do know -- we don't really know what the event was. we're not sure what is happening. there's no confirmation as to what the event was precisely. >> very quickly, what about the possibility that hostages have been taken? >> there's very strong sense of deja vu as to what happened. when you look back as to what happened in december 2014 when

there was a situation in a school where over 100 students were killed in a very similar situation, which was not a hostage situation. but we don't really know. as of right now what's going on inside. >> we'll leave it there. thank you, we'll leave it there. just recap, seven dead, 20 injured after a gunman stormed a university campus in the northwest of pakistan. we're watching cnn newsroom live. the news continues with rosemary church and errol barnett right after this. ♪ ♪ lease a 2016 lincoln mkx for $399 a month only at your lincoln dealer.

a big welcome to our viewers in the u.s. and those of you watching around the world. we're with you here on cnn for the next two hours. thanks so much for joining us. we appreciate it. >> all right. i want to actually wring you up to date on a breaking news story that we are watching out of pakistan. we've been telling you about these gunmen that entered the university there, the bacha khan university, and we understand that seven people are dead. we want to get clarification on

this. and we can now go to our correspondent there in islamabad who's watching this closely. we've heard about the seven people killed. we haven't had clarifications. we understand attackers have been killed as well. talk to us about what you know about this so far. >> reporter: rosemary, as of right now, it's a tense situation at the university campus. we know that seven people have been killed. because of the information that's coming out, it's very vague. it's very filtered. the security forces are not sharing much information. so we don't really know who has been killed, whether they're students or professors. we do -- we have been told by rescue services that there are more dead bodies, that the death toll is expected to rise, that 20 people have been injured so far.

we know that the militants are still holed up inside the university. it's an ongoing operation. we've been told by people on the ground that there's aerial surveillance. journalists can hear explosions constantly from being the situation. it's vague and tense. the it's a foggy morning and the information coming through is filtered and not confirmed as of right now. >> sofia, we understand that. is there any clarification at all on this report earlier that we had that a couple of the attackers had perhaps been killed? now we understand that there are some gunmen hiding. originally it was three gunmen that were understood to have gone into this university. has that changed? >> we know that some militants have been killed. confirming a death toll at the moment will be difficult. it's expected to rise. it could be more.

it's an ongoing operation, but it's still unconfirmed as of right now. >> and talk to us about how well equipped soldiers and police in that area are to deal with a situation like this. >> reporter: well, rosemary, unfortunately this is not something that's new to this region. just a little over a year ago last winter in 2014, a school was attacked which saw over 10 0 students killed in a situation which was tragically similar to what's unfolding at the moment. rescue services are very well-equipped. they're well versed in dealing with situations like this. there has been in recent months, there's been -- we've seen a decrease in militant activity in this particular region. over the past three days, there's been an increase in attack. we saw a check post yesterday which left ten people dead.

the security forces and the police are very well-equipped, unfortunately, to deal with something like this. the university itself had its own security personnel, most educational institutions hire private contractors to provide security to their students, so it's something that's always at the back of people's minds in a place like this. >> it's certainly a horrifying situation, and we're talking there with our islamabad producer. we'll continue to bring our viewers updates on the situation. it's different to get a grasp on what exactly has happened, but we do understand seven people have been killed in this situation that is still ongoing there. we appreciate it, sofia. with a tight electoral

contest less than two weeks away in iowa. donald trump picked up an endorsement that could put him ahead. >> the fosarah palin gave her support to trump. palin praised trump for raising difficult issues and challenging the status quo. listen. >> only one candidate's record of success proves he is the master of the art of the deal. he's beholden to no one but we the people. how refreshing. he's perfectly positioned to let you make america great again. are you ready for that, iowa? no more fussy footing around. our troops deserve the best. you deserve the best. he is from the private sector, not a politician. can i get a hall lialleluia. >> we spoke with ryan lizzer

about what kind of shock waves this endorsement might cause. >> reporter: donald trump has already been striking fear in the hearts of many republicans. i mean, you can find -- there is now a cottage industry in washington of conservative and republican-oriented columnists who are declaring they won't vote for donald trump if he is the nominee in a party. i think if there were one other figure in the republican fermment who scares where traditional conservatives in washington and elsewhere, it is sarah palin. so in a sense, he's doubling down on what was -- what a lot of republicans feared about trump in the first place. >> interesting. and then, of course, in 2012, sarah palin endorsed cruz for his senate race. now she's turned her back on him. and iowa's governor is telling

people not to vote for cruz. let's listen quickly to what he actually said. >> i believe that it would be a big mistake for iowa to support him. i know he's ahead in the poll, but the only poll that counts is the one they take on caucus night. i think it could change between now and then. i think this event is an important step to helping educate the voters in this state and this state is where it all begins. >> ryan, not a great day for cruz. what impact is this likely to have on his presidential bid? >> well, the governor in iowa is popular with republicans. he's the longest-serving governor in america right now. i would -- frankly, i think what he said today has a bigger impact than sarah palin's endorsement of trump. even among republicans, palin can be polarizing. i think what the governor is trying to do is send the message that as bad as trump is, a

cruz/trump battle that goes on for a long time might be worse for the republican parties. in other words, one of these guys can't -- shouldn't leave iowa and go on into new hampshire and the rest of the states. that would be even worse for republicans. if donald trump is going to be someone that's going to be in the race for a long time, so be it. but if they can get cruz out early, that's what the republican establishment wants right now. and the other thing, just at a simple level, it shows you that cruz, even though he's been in politics a long time, just does not have any friends, at least in the class of elected officials both in washington and out of the states. >> ryan, many thanks. always a pleasure to speak with you. >> my pleasure. bernie sanders has a commanding lead over hillary clinton in new hampshire. sanders has 60% support to clinton's 33 % among likely

democratic voters in a new poll. >> the survey was taken mostly before sunday's democratic debate. it found support for sanders has increased by 10 points since late last year. now to a staggering new report from the united nations. highlighting the devastating impact of the ongoing conflict iraq on its people. people were killed in violence in a 21-month period. >> more than 3 million people were internally displaced, and the report estimates isis holds about 35 00 slaves. many of them men, women and children. they say the real figures could be much higher. >> the commissioner has stressed that it really scratches the surface. it's the horrors that the people of iraq are facing. they're tremendous. isil is abducting young

children, recruiting them, putting them in the front lines of war. in one case we've documented, these children have fled the front lines of war because they were scared. when they got back, they were executed by isil before desertion. >> isis has confirmed the masked executioner, jeihadi john is dead. u.s. officials announced last november he was likely killed in a drone strike in syria. in the meantime, isis fighters are being forced to take a steep pay cut, and this u uss air strike may be part of the reason. their salaries are being slashed by half down to as little as $200 per month. joining me now to talk about this is jonathan, a former terrorism finance analyst at the u.s. treasury. thanks for your time. if we combine this memo with the

air strike in mosul where possibly millions of dollars of cash was targeted, how do you assess the financial stance of isis? >> i would say it hurts isis in the short term. in the long term, i think they'll be able to continue to accumulate cash. they do it through taxes, plunders, racketeering, through oil, al bee it at lower prices. they have a lot of financial gains to be made through the terrorist area they control. that is really the key to the financial success for isis. >> now, if we take a look at the typical isis sallary among soldiers, it's estimated to be between $400 to $1200 per month. they get $50 if they have a wife. an additional 25 per child.

if they're to go through this salary slash of 50%, would that impact recruitment? do you feel it would have an affect on isis's momentum these next few months? >> i think a lot of the questions resolve around whether -- that the amount of money that isis is dangling for new recruits has dropped. a lot of the times we've seen cash incentives for those that would like to cross the boarder to enter into sooe and join isis. and that cash has been a huge incentive for a lot of fighters. once they're on the battle field, they probably have less room to barter than if they tried to leave the battle field that isis enforcement, let's call them, could take care of them or perhaps punish them. and so that becomes a disincentive for them to leave the battle field. >> and what about oil fields that isis had taken control of between iraq and syria? oil is trading lower than it was

last year. how might that hit their momentum? >> this is going to hurt. we're looking at oil at 30 a barrel. when you look at isis oil, this is illicit oil that's probably trading at roughly two-thirds that. it becomes much more difficult for isis to gain a significant profit from its oil sales. again, you have to note that despite the fact that oil has been a significant driver of income, it is. the racketeering and the taxes that have brought isis, the lion's share of the cash that they've brought in. that's what we look at when we look at isis's long-term financial health. >> we appreciate you coming in and speaking about this. former terrorism finance analyst at the u.s. treasury, thanks for your time. >> thank you. we'll take a short break here. still to come, a program to deradicalize. we'll hear from a young woman who escaped isis, and her message to others who may be

welcome back. let's update you on our breaking news out of pakistan. at least seven people are dead and 20 others wounded after militants attacked the bacha khan university in northwestern pakistan. police tell us security forces are killed four attackers, but it's not clear if they are part of the seven dead. all of this still a developing situation. the death toll is expected to rise. >> so far there has been no claim of responsibility, and local officials say the it's hard to tell how many attackers are on the campus at this time because of fog and low visibility. we will, of course, bring you all the details on this breaking news story as they come into us. >> the for now we move onto this. the united nations says 400,000 syrians desperately need food assistance as the civil war carries on. they say they are under siege in

15 locations across the country with limited access to food, water and other basic services. >> they say eight agencies and the lives have been lost as a result with children and elderly at risk. syria has allowed relief to some needy syrians but officials say more needs to be done. >> let's turn to someone with extensive experience, thanks so much for your time and being with us here on cnn as we discuss aid in syria. there was a desperate attempt to get truckloads of aid into madaya last week. some died of starvation. aid eventually got through. could it be a glimpse of things to come?

>> indeed. madaya has been besieged for many years, like many other places in syria, dozens of them. we salute the opportunity we had thanks to the efforts of all partners, including members of our movement, the icrc, and as well as the u.n. partners so we can access people in need. but that's only one access that we have. we need many more, and we need to be on -- to have permanent access to people so they do not get trapped in situations they do not have control over. there is no surprise that once we get there, we find this dramatic situation being described. people are hungry. people are sick. children that are experiencing something that a child should never experience. now it's a wound in our humanity that is a wound on our humanitarian soul that we need to heal.

the way is heal it is if we cannot very quickly solve the problems, the humanitarian space be guaranteed and be protected on a permanent basis so people will get the support they need. >> and many of the aid workers who finally made it into madaya talked about coming to tears at the sights of they saw. some people without enough energy to even eat. what can you tell us about the approximately 200,000 people, most of them, women and children, trapped west, near the iraqi border inside syria. a u.n. report is saying there's a starvation risk there too. >> what to expect? if people are in a situation where they do not even access the basic needs like food, clean water, essential medicine, so what can we expect? once we're there to see really this horrific pictures. there's no words to describe

this. people, of course, are very affected with what they see, but they need to go over it very quickly and then try to gather their forces and their spirit and support people. yes, there are hungry people, people who stayed for months without even having a loaf of bread to eat. people described situations that are very dramatic such as people getting on trees and taking leaves to boil so they have something in their bellies. children who are emaciated in these situations that can remind us, and horrible pictures of wars and starvations, and all of this is totally unacceptable today, and civilians have to be protected. we need to do everything possible. and we call on all parties that are part of this conflict to find a solution to it. and beyond that, we call on all parties that bring our efforts together and then get the

humanitarian space that's required for people to be fed, that clean water comes in and then medical supplies come, and has facilities or so be protected in the same way. once again, the battle field happens to be everywhere here, and no place is safe anymore. no school is safe. no health facility is safe. no home is safe. no street, and this is really something that we need to address head on, humanitarian space has to be protected. and we call on all parties to contribute to that. >> you're in the right place. there's a lot of world leaders and business leaders there for the world economic forum. you're pushing them to do more to tackle this humanitarian issue that seems to be getting worse. we appreciate you coming to cnn to underscore that, the secretary general of the red cross and societies. thank you for your time this morning. >> thank you very having me.

despite its well publicized brutality, isis continues to appeal to vulnerable young people. but often those who are lured to join the group find their promised paradise quickly becomes a nightmare. >> that's what happened to one young woman named hannan. she escaped and is getting help to readjust in a program that the director calls a wave crashing against isis. atika shows us in an exclusive report. >> reporter: she was lured to isis territory in syria with pictures like these. promises of an islamic caliphate that was in her words, a paradise. without racism or greed, guided purely by islamic principles. instead, she says she was imprisoned, beaten and accused of being a spy. after refusing to marry an isis fighter. >> i did not understand. these girls were supposed to be my sisters.

they said they loved me. i never did anything wrong to them, but they wanted me dead because i refused to get married. >> reporter: she was lucky an, and isis court ruled there were not enough witnesses to convict her. she spoke to us on condition we don't reveal her face. she's in france under police investigation. >> when i got back to france, i was considered as a girl who tortured people, like a monster who came back pretending to be a victim. i didn't hurt anybody there. the only person i hurt was myself. >> the woman spearheading france's deradicalization program and a counselor -- [ speaking foreign language ]

[ speaking foreign language ] >> reporter: the testimonies of return knees are critical to turning recruits away from isis, but her work has always made her

the target of isis death threats. she travels with at least two body guards. for those people who want to come back and feel like they won't be accepted wac into society, what have you learned from the process and from speaking with taneia. >> translator: i always think of these girls. i'm angry at myself because i could get out but i left them over there. sometimes i think i should have stayed to plan a better escape and leave with other people who wanted to leave syria. i know there are some girls who want to come back, but they just can't. it's torture for women there. like you can't even breathe. >> reporter: hannaan says she now knows the paradise she was looking for exists only as isis propaganda. a mistake she's hoping that she can undo slowly.

still to come this hour, we'll bring you a live update on the attack on a university in pakistan. >> plus an apology from the governor of michigan. we'll find out what he's promising to do to fix the water. i think it landed last tuesday. one second it's there. then, woosh, it's gone. i swear i saw it swallow seven people. seven. i just wish one of those people could have been mrs. johnson.
