[cheering] delsym. silence is relief. this is cnn breaking news. peter kassig, also known as abdul rahman, the 26-year-old who had actually gone to syria to volunteer as an emt has now been beheaded in syria by isis militants. this breaking news just coming to us within the last hour. isis in fact had threatened to

behead him last month, but they did in fact behead him. we're just getting this breaking news within the last hour. he was captured about a year ago during a humanitarian mission in syria. his mother had actually been pleading in many videos for his release. she even took to twitter to plead with isis over twit to release her son. this is a man who had been described by a lot of people as being compassionate, so moved to help those who were suffering in the middle east, we know that he was deployed in iraq back in 2007 as an army ranger. he became passionate about the middle east and decided to go there to help. if you are just joining us, we're getting pretty big breaking news into cnn that the fifth u.s. -- or rather western hostage has been beheaded in syria. joining me now to talk about this is will gettys, an international security expert. will, obviously this is horrific news. my heart certainly goes out to his family members.

what is the best way for the u.s. to prevent more lives being taken by isis? >> i think that's an incredibly difficult answer to a certain extent. it is quite evident that they have two categories of hostages they've been taking. there are a large number of locals and also internationals that they've held hostage, negotiated with their host countries for their release. but there's this other category, the second category as you say, of the five western hostages that have been used purely as a political tool in isis' propaganda to influence as much as they can the west but also potentially from this new video the arabian coalition in trying to cease and carry out cessation of their action obviously against isis positions across iraq and syria. >> you know, we know isis has

more hostages. i mean, are they going to continue beheading western hostages as long as the air strikes continue? is that what we're going to see more of? >> i think it's unfortunately a very sad likelihood. i think certainly as far as isis are concerned, we've seen they've used the media to their advantage in trying to propagate their distorted message. where in the past we've seen obviously these western hostages being used as their tool. in this most recent video -- in this recent video what we have seen is what is believed or seems to be a number of syrian soldiers that are also beheaded or executed certainly within this video. now, this may be, if this play to be try and influence the arabian coalition who have been brought on board, preventing

isis from taking more and more ground. >> the policy that the u.s. has of not negotiating or paying ransom to terrorists, given that so many other european countries do pay ransom, how wise is that given how many lives are being lost? >> well, this is always the incredibly difficult decision for any country to take. but there are two standpoints that any country that has stood fast against negotiating with terrorists and particularly with groups like isis in so much as, "a," they set a -- not necessarily in financial or political persuasion but in terms of providing support on infrastructure which can be done in a far more discreet and far more low-key level. but when it's escalated to this

kind of international media publication and it is very much represented with a ransom that has a political influence, it is virtually impossible for any government to agree to this. and secondly, it then sets obvious lit danger not only of the future but possible nationals being taken hostage in the future but also secondly, hostages have been historically. the families would no doubt ask the question as to why there has been a change in policy to negotiate with these terrorists when their family members have unfortunately, you know, been a result of a product of the negative outcomes. >> we've heard, you know, u.s. president barack obama talk about the fact that not paying ransom actually saves american lives in the long term by making them less attractive targets. but what determines the timings of these beheadings? is there any reason why you think peter kassig was beheaded

now? >> well, again, it's a very difficult one to speculate on. and one can only speculate. unless they make it very clear themselves within their statement. as to why they've chosen this particular time to either undertake this execution or "b," to promote the actual video. one can only see that certainly isis trying to reinforce their strength if you like by saying we are still resilient, we're still robust. we will continue to execute foreign nationals and we'll continue to do so until we see influence being brought to bear by the uk and other members of the coalition. unfortunately, i don't think this will be the end of it. i think unfortunately we'll see many more executions potentially into the future. >> you mentioned a while ago that it's probably not wise for the u.s. to pay ransoms. but is there anything to stop the parents or the family members of these victims from raising the money themselves?

legally, i guess. >> any part of a negotiating process is really establishing communications channel. it's communicating with those that are presenting the official negotiators on behalf of isis. there are many individuals within the local region which inevitably have presented themselves as supposedly a spokespers spokesperson. as you want to call it, ambassadors for them. it can be discussed or entered into dialogue with to try and effect any kind of concession but ultimately for any family to take this individually or independently would be fraught with all sorts of potential difficulties. the negotiation process is complex, even when you're organized with or arranging these processes with a group that's highly organized and is professional. as we've seen with other criminal groups around the

world. it is a money-making exercise for them in many respects. when it's escalated to a political level, there is probably very, very, very small likelihood that the family would be able to achieve any positive result. >> okay. will geddes, thank you so much for being with me. we'll take a quick break. more breaking news when we come back. wear the enamel. i recommend pronamel. pronamel helps to defend the enamel from the acids in our diet... it helps to strengthen the teeth. so you can see like right here i can just... you know, check my policy here, add a car, ah speak to customer service, check on a claim...you know, all with the ah, tap of my geico app. oh, that's so cool. well, i would disagree with you but, ah, that would make me a liar. no dude, you're on the jumbotron!

australian prime minister tony abbott issued the g20 summit's communique just a few hours ago detailing what the member countries plan to work on and fun. the prime minister said this weekend was an akmeefment that has set an aggressive agenda for fighting climate change, ebola and spurring global economic growth by trillions. >> we've signed off on a peer-reviewed growth package that if implemented will achieve a 2.1% increase in global growth over the next five years on top of business as usual. the brisbane action plan contains over 800 separate reform measures. and if we do all that we have committed to doing, the imf and the oecd tell us that our gross

domestic product will be, as i say, 2.1% higher than it would otherwise be. and we've published these measures. we've published the growth strategies so the world can see what we are committed to. and the world can hold us to account. and the oecd and the imf will be regularly reviewing our progress towards achieving these measures to keep us accountable. >> the australian prime minister tony abbott speaking there. some g20 leaders, including the u.s. president, are also pushing russia to change its course in ukraine. they suggested more sanctions could be on the way if russia continues to interfere and not let ukraine take charge of its future. cnn's senior white house correspondent jim acosta joins me live from brisbane. we heard prime minister tony abbott speak about pushing global economic growth by 2.1%. but how much was the summit

overshadowed by president vladimir putin and ukraine? >> reporter: it certainly was overshadowed by vladimir putin and ukraine. you were just talking about the alleged beheading of peter kassig, the american aide worker. i want to let you know, zain, in the last couple of minutes we received a statement from the white house, from the national security council at the white house about that situation. i'm just going to read it to you on air because you don't have the statement to put on screen. this is from bernadette meehan, the statement says we are aware of a video that claims show the murder of peter kassig by isil. the intelligence community is working as quick as possible to determine its authenticity. if confirmed we are appalled by the brutal murder of an innocent american aide worker we express our deepest condolences to family and friends. we'll provide more information when available. that is almost word for word what the national security council at the white house sends

out just about every time we have a situation like this. in the initial first hours because they don't have this verified or authenticated. they have to sort of couch it in those terms. they'll eventually say they don't have reason to doubt the authenticity of that video. in this situation, the intelligence community in the united states will still have to look at this to verify whether or not this is indeed authentic. that's the first response we have from the white house. we should point out, president obama is on air force one right now flying from brisbane, australia, back to the united states. he's going to have a refueling stop in hawaii on the way. presumably the white house and communications staff will get comps back and perhaps offer further guidance, more information in terms of whether the president has been briefed on this and how much more information they can provide to us. get back to the matter at hand that you asked about, zain, yes, the g20 summit was overshadowed by vladimir putin.

you saw the world leaders with the tough talk, aimed at the russian president. president obama also weighed in in that speech at the university of queensland wred yesterday. during a news conference, he talked about the various interactions he's had with the russian leader, not only at the apec summit in china but the g20 summit as well. here's what the president had to say. >> i had naturally several interactions with president putin during the course of the apec summit and then here at the g20. i would characterize them as typical of our interactions which are business-like and blunt. and my communications to him was no different than what i've said publicly as well as what i've said to him privately over the course of this crisis in ukraine. >> reporter: now, on the situation with isis, that topic also came up at the news conference and the chairman of the joint chiefs for the united

states armed forces, martin dempsey, he had been saying in recent days he may envision scenarios where he may have to recommend to the president the need to send in u.s. ground forces to fight alongside iraqi security forces to take the fight to isis. i asked the president today during the news conference whether or not he shares that potential for a scenario that he might envision where ground forces may have to go into combat which by the way may be a reversal of sorts because the president has ruled that out in the past. here's what the president had to say about that. >> yes, there are always circumstances in which the united states might need to deploy u.s. ground troops. if we discovered that isil had gotten possession of a nuclear weapon, and we had to run an operation to get it out of their hands, then, yes, you can anticipate that not only would chairman dempsey recommend me sending u.s. ground troops to get that weapon out of their

hands but i would order it. >> then on domestic concerns, the president was asked about this expected executive action that he's beginning to take to provide deportation relief for millions of undocumented immigrants back in the u.s. the president saying in his remarks during that news conference that this is still the plan because republican action up on capitol hill, because they have not passed a bill that would address this problem in the u.s., the president plans to issue that executive action. could come as soon as next week. zain? >> so many issues on the president's plate there immigration, climate change and of course now the beheading the peter kassig, very tragic and sad news. jim acosta, live in brisbane. thank you. we appreciate it. speaking of russia and ukraine, ukraine's president, petro poroshenko has taken the first step towards cutting off all government funds and statuses to pro-russian rebels in eastern ukraine. petro poroshenko issued a decree

saturday calling for all state-owned companies and institutions to stop services in donetsk and luhansk within a week. the order comes off rebel leaders from the donetsk region held their new government's first official meeting. the meantime, shelling tens in the east, despite a cease-fire reached in september. phil black joins us live from ukraine. this decree, phil, how much of a setback is it to the rebels in yeern ukraine? >> reporter: well, zain, it is certainly symbolic in the sense that it appoints to a further e deterioration between kiev and the separatists since signing that cease-fire in september. but the reality on the ground is that it may not change things too much. this has been a conflict zone forrette better part of the year. the government in kiev has not been effectively delivering its services to this region. it simply hasn't been able to. its officers have been closed or seized. its infrastructure destroyed or damaged by the separatists and

the fighting during these long months of conflict. so the reality on the ground may not change too much. but it is another sign that that minsk agreement signed in september has come to very little. ultimately because the fighting has never stopped. we got a sense of this when we visited what is effectively the front line of the ukrainian positions, one of their most forward military positions, facing off against the separatists just a short distance away. this is what we saw. fighters in the mist. this armed camp is an exposed outpost of the ukrainen military. about 30 men, volunteers from the capital, defending a narrow finger of land. their tanks, weapons and defenses point to the east, south and west. their enemy is close, somewhere through that haze. they say the pro-russian separatists regularly attack. >> this they say is shrapnel.

came into this position just yesterday. they say two men were killed here yesterday, 40 in the last month. to these men, september cease-fire means nothing. so do russia's denials about sending fighters and weapons across the border to help the separatists. they say they know they're fighting russians and they expect a major attack very soon. to prepare for it, they have been working underground. >> this is where dozens of these men sleep at a time. you can see there's one catching some rest just here. they dug this for themselves only a few weeks ago. concrete ceilings, timber supports. they desperately hope this would be able to withstand a direct hit from rocket or artillery, or a mortar strike. in this place where they sleep, you can see they read, keep cigarettes. it is so close to where the action is. out through this door, come and have a look.

defensive trenches heading in that direction and the other direction as well. because the fighters here tell us that only about 800 meters that way are the forces of the pro-russian separatists. >> reporter: a short drive away is another town, what's left of it. this is government territory. locals say artillery fired by both sides falls here almost every day, often destroying homes. this is a strange, eerily quiet place but clearly it has not always been so. most of the people here have left. the locals tell us it's mostly the young people that have gone behind, the old remain. they say they are too scared and they don't know where else to go. this 73-year-old woman tells me of the terror of living under bombardment. she says she feels like her heart will jump from her body. she's too scared to eat or sleep. these people have little food or power.

they dread the coming winter. and they don't care who rules over them, they just want peace. zain, the key question is what happens now? the ukrainian government believes russia has moved large numbers of troops and weapons into that separatist territory. russia denies it but the ukrainian assessment is that some sort of large military initiative is about to be launched by those pro-russian forces. they believe that because they say that's what's happened through the year whenever large number of russian soldiers have shown up on ukrainian territory, whether it was crimea or the ongoing conflict in the east. that's their expectation. the fighters that we met at that base, they believe it's coming. they say they are committed to stopping it. but they are not a professional fighting force. they endo the have the skills, resources or discipline of one. in the event that a major separation by the separatists is

launched, those fighters will have a tough time holding on to that position, zane? >> leaders at the g20 summit saying that they plan to increase sanctions against russia as long as those rebels stay in eastern ukraine. phil black, live for us in ukraine. thank you. we appreciate it. dutch safety board officials say the recovery of the wreckage from the malaysia airlines plane crash in eastern ukraine is now under way. the dutch have commissioned the recovery and transport of the wreckage to the netherlands. it's all part of the investigation into the cause of the deadly crash. over the weekend, western leaders at the g20 summit demanded justice for the 298 people killed in the july downing of mh17 in eastern ukraine. the entire recovery operation is expected to take several days. investigators intend to reconstruct a section of the downed aircraft. a doctor with ebola has arrived in the united states to be treated. straight ahead, what we know about his current condition.

up next, more on our breaking news reports that peter kassig, an american aide worker has been killed by isis. i'll talk with an expert who deals with extremism and radicalization. that's coming up. shh! taste better in our savory broth. vegetables!? no...soup! oh! soup! loaded with vegetables. packed with taste.

this is cnn breaking news. welcome back, everyone. for those of you just joining us, i have very sad, tragic, devastating breaking news to report. peter kassig, also known as abdul rahman, a 26-year-old who had gone to syria to volunteer as an emt has now been beheaded by isis militants. isis had threatened to behead him last month when they beheaded british aide worker

alan henning. and his mother had really been pleading with these militants to release him. we saw videos of his mother pleading to let her son go. it's her only son. she took to twitter begging to are a response from isis as well. his family described this young man as passionate, desperate to help those in need. we know kassig was deployed in iraq in 2007 as a u.s. army ranger. he then decided to go back to the middle east to help those in need. and now we have the tragic news that peter kassig, 26-year-old peter kassig who had gone to syria to volunteer as an emt to help war-torn victims hoz now been beheaded by isis. we know he's been in captivity for about a year and that isis has by the way said these beheadings would continue as long as the air strike campaign continued. and he has been captive as i mentioned for about a year. the u.s. obviously has a policy

of not negotiating with terrorists. okay, joining me now to discuss this further is haras rafik. this is sad, tragic news about peter kassig's death. is there anything we can learn about the timing of this beheading? is there any reason why isis chose now to commit this heinous act? >> yes, first of all, my heart goes out to peter rahman kassig's family. if you watch the video, there are interesting dynamics. it's a professional produced video that's been edited. the assassination, the beheadings didn't just take place yesterday. this video has been compiled over a number of days and produced yesterday. i think that isil are becoming more and more desperate. as they're being hit hard by air

strikes, the unfortunately the videos that we're going to see are going to are more and more barbaric. this one was a particularly barbaric one. they marched a number of syrian soldiers as well and for the first time showed the gruesome beheading of those people. i think it's a sign of desperation. i think it's a sign that they know and feel they're under attack, under siege and they are struggling and they're now trying to show that they are operating from perceived strength. this is the propaganda war they're fighting. >> even though there are is a video online showing the beheading of period of time kassig, we have not been able to confirm the authenticity of that video. i want to remind our viewers of that. is there any expectation, given that peter had converted to islam, was there any expectation his life might be spared?

>> i don't think so. if you look at the beheadings isil have been doing over the last year and a half, they've been beheading muslims, other sunnis, shias. essentially peter, rahman as he wanted to be called, was a muslim, just not their kind of muslim. this is an interesting factor here. anybody that isil believes who is a muslim and not that kind of muslim, they will see as an enemy. and it doesn't matter whether you convert to islam or not, unless you convert to their particular brand of islam, you'll be classed as an enemy. i don't think there was any expectation. >> i think what a lot of people find absolutely heartbreaking about this is that this is a man who had gone back to the middle east to help those in need. he was an aide worker just like the other two british men were, david haines and alan henning.

was there any expectation that perhaps being an aide worker, perhaps the fact that he, just like david haines and alan henning had gone back to syria and iraq to help those in need, that isis would spare their lives either? >> no. this is a barbaric group. this is a group that was considered too barbaric for al qaeda. al qaeda kicked them out as they were because they didn't agree with their tactics. it doesn't matter to them whom they're killing, what role that person played in the region, because you're right, peter rahman kassig, alan henning, many others were aide workers and were there to do good and help the people in syria. these guys don't care. they're not fighting against bashar al assad. they don't care about anybody coming to help. these guys have been fighting for a long time, this so-called

islamic state. and anybody, irrespective of who the person is, they consider them to be an enemy of stat. >> one thing the u.s. has repeatedly said, the reason they don't pay ransom or negotiate with terrorists, it will likely make americans less attractive hostages in the future. do you think that's true? >> i think by paying ransoms what it does, it increases the likelihood of more american hostages being captured. if you look at it from a practical perspective, if any terrorist entity or even any criminal entity knows that they are going to get money by kidnapping certain types of people, they're assured of getting either finances or some sort of negotiated truces or some sort of -- something in

return, they're more likely to target that type of person. i think it's a sensible strategy, a strategy that we have here in the uk as well. americans, europeans, britains, we are all targets, even other muslims, we're targets by the fact of the way we live, what type of individuals buy into their world view. we're absolutely right not to negotiate with these guys. mr and more american citizens will become easier targets and they'll get a better return on their investments as it were in terms of taking captives that are american. >> and given the fact that you know, isis has released a number of european hostages whose countries have paid these ransoms, is this more about the air strikes or the fact that the united states doesn't pay ransoms? if the air strikes continued but the u.s. paid the ransom, would peter kassig still be alive? >> no, absolutely not. because if you think about it,

peter rahman kassig was captured a year ago. there were no air strikes at the time. other hostages were captured a long time ago, again, no air strikes. this is part of a strategy, part of a well-calculated propaganda war and irrespective of whether we are taking air strikes or not at the u.s. and the uk, these guys were still in captivity, being tortured and these guys were being used for propaganda at wars in the past. i think air strikes don't play a part in this all. however, what i do believe is that the air strikes are dictating the way that these guys are playing the propaganda war. now, the other thing is we don't actually even know when peter rahman kassig was behead. we know the video was released in the early hours. it's morning in the uk. we don't know when the

assassination took place. there is a belief, it's been reported in the uk press today, that jihadi john, the person seen in the video, was severely injured last week in the u.s. air strike. so we don't actually know when these videos were made. i think it would have happened anyway, just the timing is based on the air strikes now. >> yes. so many unknowns. obviously very heartbreaking news especially when you look back at those videos of his mother pleading with isis, saying this is my only son, please let him go. obviously he was there to help the people of syria and iraq. all right, haras rafik of the quill quilliam, foundation, thank you.

welcome back, everyone. while answering questions at the close of the g20 summit, president obama said he still does not plan to deploy u.s. ground forces in iraq. in recent days the u.s. chairman of the joint chiefs of staff, general martin dempsey has suggested that he might recommend ground troops to mr. obama. general dempsey made an unannounced visit to iraq on saturday. he says the tide is turning in the battle against isis in iraq. senior international correspondent arwa damon reports on the significance of the trip. >> reporter: america's top military man's surprise visit to iraq, a clearenication of how

seriously washington is taking the situation. general martin dempsey meeting with the iraqi prime the two spoke about progress being made so far by the iraqi security forces. general dempsey then also traveled on to irbil, the capital of the autonomous region of kurdistan, meeting with the prime minister there as well. part of this next phase of the u.s.-led mission and coalition is to focus on a training of security forces, 12 units, part of the initial effort. nine of them iraqi army, three of them peshmerga. general dempsey speaking with military commanders on the ground wanting to get an idea of what it is they need to be able to move this mission forward. general dempsey is very aware of the situation on the ground, having been the commander of the first armored division in the issue years of the war and then

moving on to head up america's effort to train and equip the iraqi security forces. this assessment is vital because part of the reason why isis was able to take over such great territory in iraq is because of the u.s.'s, perhaps underestimation of their capabilities but also overestimation of the capacity and cohesiveness of the iraqi security forces that america left behind. and that is not a mistake that the u.s. or the region can afford to see happen once again. arwa damon, cnn, turkey. >> in the meantime, the u.s. is doubling the number of military advisers in iraq. okay, anger continues to build in mexico, seven weeks after dozens of college students disappeared. they were studying to become teachers. on friday, the former mayor of iguala, a town near acapulco was charged with masterminding the abduction and probable killing.

in another town close by, a teachers union is calling for stronger government response. rosa flora has more on the response. >> reporter: in guerrero, they're known for some of the most explosive demonstrations. the fire department just arrived. guess what, not only are the cars burning but the inside of the building is also burning. all in in support of the search for 43 missing students. lunging at police. a cnn camera captures protesters taking an officer captive over a tug of war over a bridge. he was later released. the protesters are members of a teachers union from all over the southern state of guerrero. when night falls, a stark contrast. soft spoken people enjoying time with friends and family.

the protesters granted cnn air access inside their tent city in the main square of guerrero's capital. they shut down city hall and moved in days after the 43 students went missing. it's been more then a month. how many teachers are there? 5,000? the announcement more than a week ago by mexico's attorney general that three drug gang members confessed to killing the students only made the protesters more angry. to date, no dna evidence has been presented. >> he says they feel the pain that the parents of these missing students are feeling. >> reporter: little sleep happens here. teachers take turns guarding their makeshift homes at night and protesting during the day. >> i was asking him about the

charred cars, the charred buildings, if we are to expect more of the same. and he says that, yes, they're ready to do more of the same. >> reporter: everyone in the tent city has a home, a family, a job and even though the basics of living are rough here -- >> she says there's public showers where they're able to pay 20 pesos and they can take a shower. >> reporter: they don't plan to go anywhere until the students are found, even raising their own flag in the city square. he says that the flag is a symbol of their fight. don't mistake their kindness in the camp for weakness on the streets. protesters taking it to a whole other level. they vow to make the government listen to their demands. rosa flores, cnn, mexico. by the way, the mayor of iguala has been charged in the disappearance of those students.
