and then he tracked her down and he killed her. and no conviction is justice for what happened to her. but ironically, the science that she was working on, in fact, helped put away her killer. -- captions by vitac -- www.vitac.com a cease fire maybe sticking in ukraine, boosting hopes after a prisoner swap. hollywood's biggest night is hours away. a glimpse in how the famous gold statuettes are made. welcome to our viewers in the united states and around the world. i'm george howell. this is cnn newsroom. >> we start this hour in iraq. isis and another video. this time showing captured kurdish fighters.

we see peshmerga soldiers in cages. they threatened them telling them to abandon their jobs or face a similar fate. cnn can not independently confirm the authenticity of the recording. cnn is on the ground in iraq. let's go to senior international correspondent ben weidman who is live in erbil. you have been on the lines with these fighters. do you get the sense, do you surmise this video will have any impact on their resolve? >> it's clear from the video itself, george, that's the aim of isis in putting out this video showing 21 of their comrades in cages and certainly hanging heavily over this video is an implied threat that these people will suffer the same fate as so many others we have seen in libya and syria. and iraq but it does not appear this will make a major impact on

the resolve of the kurds. they realize this is in a sense, a fight for their very existence. isis has very little tolerance for the fact the kurds seem to want to determine their own fate and not throw their lot in with the dark ages mentality of isis. now certainly -- we are hearing other information, other news that may bolster the morale of the kurds. we understand overnight there was another major assault by isis in the area where earlier this week they fought for five hours trying to break through kurdish lines. in this instance the action took place south of erbil, an hour and a half drive. according to our sources, at least 50 isis soldiers were killed after a battle that lasted an hour and a half and involved coalition air strikes, as well with. they say among the 50 bodies that they found of dead isis

fighters that there were foreigners as well. there's also been action in the sinjad area west of here near the syrian border where peshmaga forces joined with the kurdish fighters from syria who came in to iraq to join in the fight against isis there. despite the propaganda put out by isis it does appear when it comes to the kurds isis is on the defensive. >> then this propaganda we're not showing the video. with we are showing images if even that. not playing in to this but the video uses music shows images and important we cannot confirm these men have met a demise in this video. correct? >> that's correct. what you see are flashes of

stills of the egyptian christians killed in libya last week. certainly know there's no indication the kurdish fighters have been killed in this instance. certainly the indications are their fate will not be a happy one, despite the importance of compassion in islam. it does not appear that isis has much compassion for those it takes prisoners. >> i want to ask you one other question about the weapons that isis seized, american weapons that it recently seized. what more can you tell us about that? >> this is a video that was posted day before yesterday on facebook. it appears to show isis fighters overrunning an iraqi army base. we understand it is about 100 kilometers to the north of baghdad. our sources indicate that incident actually happened earlier in february.

it was only the day before yesterday the video was posted. what you see is them displaying about 35 by my count u.s.-made m-16s. it's important to stress they are u.s. made but of course in the possession of the iraqi army at least they were. in addition to that, you see a pile of ak-47 assault rifles. you see some armored personnel carriers also american made as well as a humvee and lots of ammunition morter and rocket-propelled grenade launchers. this is the latest incident along those lines swrechl seen in time after time particularly in anbar province as isis has taken over one iraqi military installation after another. last june when the iraqi army fled with their tail between their legs from mosul, they left behind a huge amount of

u.s.-made equipment and ammunition. as we have seen time and time again, they take over more bases, they get more of these u.s.-made weapons. george? >> senior international correspondent ben wideman in erbil, iraq. with we appreciate your reporting on the ground there. new threats against the west. in this case a sew mallian terror group linked to al qaeda. it comes in the form of a video released by al shabaab. the man in the video a calls for attacks on shopping malls in the u.s. and united kingdom one suggested the mall of america seen here in west edmonton mall in alberta, canada. both say they have stepped up security. al-shabaab was responsible for the devastating massacre on westgate mall in tween 2013. you will remember that left dozens of people dead. we go to eastern ukraine

where there are new signs that a tenuous peace agreement may be holding. look at this video just in to cnn of a prisoner exchange between ukrainian and pro russian separatists on saturday. president poroshenko confirm the release of 139 ukrainian troops for 52 pro russian rebels this has they are preparing to draw back heavy weapons from the front lines wchl ve the latest developments from kiev. >> there have been a few signs in the past 24 hours that could be interpreted as being positive in the shaky cease fire process in eastern ukraine. the prisoner swap with has been taking place. the ukrainians say pro russian separatist released 139 ukrainian soldiers from captivity and they were bussed back to ukrainian-controlled territory. for their part ukrainians said they released dozens of people

who will be making their way back to the territory controlled by the pro-russian separatists. another thing that could be positive step is the pro russian separatists said they believe the bulk of the fighting operations are over and they have given an order to start making preparations to withdrawal heavy weapons from the front line area. that's very significant. according to the agreements that would be the next major step to happen is for both sides to withdrawal heavy weapons away from the front line area to make sure that no fighting ensues there again. of course ukraine for its part today is marking one year since former president was forced to leave the country, forced to flee by helicopter. there will be a solidarity march through central kiev, centering around the area where the uprising start ed a year ago. the president of germany will be coming and polish leader and

leaders of other countries will be here as well. also an exhibition that ukrainian president poroshenko will be visiting where ukrainians are trying to show they have evidence of direct russian involvement in the fighting going on in eastern ukraine. the russians continue to deny this. >> so while there are hopes that that truce will hold u.s. secretary of state is threatening more sanctions against russia after what he calls unacceptable actions in ukraine, despite moscow's denies of any direct involvement in politics in the conflict in. secretary kerry said in this age of satellites and intelligence it is no secret what russia is up to. let's listen. >> we know to a certainty what russia has been providing to the separatists, how russia is involved with the separatists and the ways in which russia has been cynically willing to go

even lead an effort at the u.n. even simultaneously as it is continuing to do land grabbing in ukraine. later this hour we expect kerry and his iranian counterpart to arrive in geneva for the nuclear talks. they are expected to join other world powers who have been in talks since friday. we will have live pictures are geneva wauns once the talks get underway. turkey's military has successfully completed an evacuation of soldiers guarding a turkish held tomb in syria. 40 soldiers guarding the tomb of suleyman shah went in according to though turkish prime minister. he explained the conflict and state of syria posed risk to safety and security of the tomb. officials say one turkish soldier was killed in an

welcome back to cnn newsroom. i'm george howell. a minnesota police officer is recovering after he was shot when responding to a burglary. the shooting happened early saturday morning in minneapolis. a man was arrested in connection with a burglary and reported domestic assault. investigators do not believe this particular officer was the intended target. >> the officer was not at his squad car when this happened. he was outside of the squad car. it's clear to us the officer was shot in relation to his response to the call. it didn't seem at all, to us related to the information that we have at this time that there would be any reason to shoot this officer other than him targeted for him doing his job. >> detectives are looking in to whether the reported assault, the burglary and the shooting are all related. there's a new u.s. government report that warning of armed domestic terror groups

in neighborhoods around the u.s. and some law enforcement groups say the threat from home grown groups is greater than that from foreign groups. cnn's nick valencia has the story. >> reporter: from california to florida, all across the united states sporadic attacks on law enforcement by sovereign citizen extremists. a new intelligence estimate circulated this month at the department of homeland security puts a focus on domestic terror threats. >> unfortunately, there's a number of those tloout throughout the united states that we have to be concerned about. deadly plots like this one last year in georgia armed with several explosives smoke grenades and plenty of ammunition police say dennis marx showed up ready to kill. deputies shot and killed marx after he tried to drive his suv in the courthouse. the fbi's assistant director tells cnn there maybe thousands of others like marx ready to

attack. >> we have been talking about the international terrorism threat but there are domestic groups just as concerning that we worry about here in the united states. >> reporter: a recent survey listed sovereign citizen terrorists ahead of foreign islamic terror groups like isis and domestic militia groups as the top domestic threat. by some estimates 300,000 sovereign citizens in the united states today. >> their believes go back 20 25 years or even further. essentially they believe the federal government has no jurisdiction over them. >> the latest dhs report counted 24 violent sovereign citizen-related attacks since tween 2010 with law enforcement officers as the primary target. >> they have no baysis in reality. they are often telling people they can get something for nothing. they don't have to pay their taxes, they don't have to pay credit card debt.

so there's that kind of teaching going on around the country and that's driving this movement. >> reporter: it is not just violence authorities are worried about. it is also so-called paper terrorism which is the process of burying court officials with nonsensical filings and they are required by a matter of law to file the documents and track them even though they have no idea what they are looking at. nick valencia cnn, atlanta. more people are reacting to the remarks by former mayor of new york allege religion that u.s. president president obama does not love america. giuliani made these comments at a private dinner for a potential presidential candidate. our will riply reports giuliani is doubling down. >> reporter: new york's former mayor rudy giuliani is not backing down standing by his charge that president obama doesn't love his country. telling jim acosta in a phone interview he refuses to

apologize. >> he said to me during this brief conversation i don't regret making the statement. i believe it. >> reporter: giuliani addressed the firestorm following his comments. >> the former a mayor said his officer has received death threats. he said the secretary has gotten some death threats over the phone. >> reporter: while cnn can't verify the claim giuliani said the majority of messages were positive including one from bobby jind jindal. he refused to condemn the former mayor but said he should have chose different phraseology. not all democrats are backing the criticism of the president. >> i think it is a mistake to question people's motives. it is one thing to disagree on policy. i try not to question the president's motive as being a good or bad american. >> reporter: giuliani's recent behavior is no surprise to some 0 who followed his political career. >> he's going to down double down triple down and quadruple

down. >> reporter: he says the man hailed as america's mayor for his looel leadership during 9/11 is tarnishing the legacy. >> he's enjoying this. this is an ego trip. rudy's been out of the news and now he's on the news. >> reporter: giuliani continues to make front page news this weekend bringing up old claims about the president's past. we haven't mentioned the other communists and leftists who educated him as a young man. >> reporter: former senior adviser david axelrod dismissed the criticism in an interview with michael smerconish. >> i can't climb in his head and explain why he said what he said. what he said was despicable and inconsistent with the man i know and the man i think most americans know. >> reporter: giuliani is defiant, even as he risks stepping farther away from his image as america's mayor. will riply, cnn new york. switching with to weather.

parts of the east coast and united states cannot catch a break from the cold weather. we will have the latest from the world weather center on the continued cold blast.

welcome back. an unrelenting arctic blast is making some parts of the united states look something like the ice age. meteorologist derek van dam is at the weather center. it is like we talk about this

week after week with after week with especially in the northeast. they are tired of this. >> enough already is what everyone says to me. it is like don't hate the messenger. it's not my fault. another snowstorm that we are currently tracking across the big cities along the east coast, including washington, d.c. new york, and, yes, boston once again. this is the latest watches and warnings in effect. you can see the shading of pink from new york to philadelphia just outside of washington. that's a winter storm warning. we have snow and a wintry mix ongoing across this region. in fact, that has allowed people to take yes, selfies in front of the white house in washington, d.c. obviously a national monument there. you can see the fresh layer of snow. our radar is currently lighting up like a christmas tree with all kinds of colors from atlanta to boston. of course that representing rainfall, the shading of blue and green and you can see the

ice coverage and it's interesting to note as well that the great lakes often help to develop what is lake effect snow from these cold surges of air masses that come down from the arctic. when we get that full coverage of ice over the great lakes, it actually closes off the tap of the snow-making machine. here's the cold blast of air moving across the east coast. if you are traveling to new york, monday you have another cold day ahead of you. bundle up. here's our forecast windchill temperatures to start off the early workweek. hey, george back to you but i will will leave you with this nice photo. someone captured this with the sun in the background. >> really cool. >> i'm new to cnn international but was in the cnn chicago bureau and we had a great view just right on lake michigan where the snow would come in from the lake effect and it was so intense every time it would

happen. >> it has to do with the direction of the wind. so crucial. >> intense. thank you so much. >> welcome. nearly 3,000 texas inmates will be relocated to a new facility after several fires started during a lockdown. on friday prisoners at a federal prison in south texas refused to participate in work duties and complained about medical services. prison official ordered a lockdown. 2,000 inmates broke out of their housing units and went to the recreation area. officers used tear gas to bring the situation under control. what a situation there. greece's prime minister declared victory on saturday after agreeing to a financial rescue deal that will avert a banking collapse. the trouble is far from over. >> reporter: yesterday we won a battle but not the war. the difficulties not just those regarding negotiations and relations with our partners the real difficulties are ahead of

cnn cannot authenticate the video or where it was recorded. peshmerga fighters have been most successful in pushing isis back in iraq. 6r789s a somali terror group linked to al qaeda made threats. al shabaab calls for attacks on shopping malls in the u.s., can diana canada and the united kingdom. they say they are beefing up security. an evacuation of soldiers regarding a turkish held tomb inside of syria. 40 soldiers guarding tomb of suleyman shah went back to turkey on sunday. this is according to the prime minister. officials say one turkish soldier was killed in an accident. there are new signs of a bolstered peace agreement in ukraine after pro-russian rebels and ukraineian forces swapped members.

poroshenko confirmed 139 soldiers were released on saturday and russian state media report 52 rebels were freed, as well cnn calls it isis. government agencies and other agencies call it isil. the terror group calls itself the islamic state. one name could spark a violent reaction from the extremists. ben weidman explains. there's a name that isis hates being called despised so much, in fact they threatened to cut out the tongues to anyone who uses it. that name daesh. there is a big discussion what to call the group. we say isis others say isil. islamic state is what they like to be called but what they hate is daesh. it translates 'as the islamic state in iraq, the name before

last summer. many arabic speakers still call them daesh. what do they hate about it? some say it sounds like other words that can mean to stomp on something. some isis supporters they want the full name of their state to be shared with the world. there is a push to call them daesh to deny them the legit macy. what about other names in english, isis, the islamic state in iraq and syria or isil the islamic state in iraq and levant. but it leaves geography out of the mix. but can anyone call them an islamic state in they hold land which is one of the attributes of a state and they have in some areas what amounts to a

government but they are not recognized internationally as a state, just a terror group and there's no consensus on whether they are actually islamic. to supporters isis is the essence of islam and everyone else an infidel. a notion rejected as absurd by countless muslim scholars and believers around the world. isis fighter and supporters insist they follow the path of allah, god and the west is hell bent on battling islam. >> that's how they recruit, how they try to radicalize young people. we must never accept the premise they put forward. because it is a lie. >> reporter: whatever we call it and it calls itself daesh, isis isil islamic state, it is what it is a group without scruples bent on spreading a rain of terror. another story here north korea, the leader of the country

has a new look. kim jong-un is turning heads with his dramatic hair cut and there maybe another reason other than style behind his transformation. >> reporter: a bold transformation from last year's stylish flop cut to an extreme flat top. kim jong-un presides over a political meeting in north korea, brandishing a new hair style that's getting a lot of attention. they say it is a calculated look. >> he wants to project the image of his grandfather kim sung. he gave them independence. he fought against clen yalians and japan and the united states. kim has been ratcheting up his projection of power his message to the people he will take on america. a south korean news agency reports that kim visited several military units over the last

several months telling them be ready to fight. he reportedly conducted the first test of a ballistic missile intended to be launched from a submarine. it's an ominous maneuver. analysts say when north korea figures out how to outfit submarines with missiles they could move undetected. >> north korea could launch strikes against american forces in japan or south korea, sneak up on our bases in hawaii or if they make it to american ports launch nuclear missiles against american targets. >> reporter: the pentagon won't comment on the laftest missile test and a new level of concern that north korea isn't all bluster anymore. the sony hack a massive cyberattack the company is still reeling from thought to be ordered by pyongyang showed this regime can and will hit americans where they live. human rights advocates say kim jong-un is acting aggressively on another front as well. expanding a program of sending north korean workers a abroad.

they toil in factories, build statues for dictators in africa and forced to send virtually all of their money to kim and his cronies. >> dispatch aing north korean workers overseas is meant to earn the regime the hard currency of needs to stay in power and to help to pay those who maintain the kim regime in power. >> reporter: analysts say they need the currency more now because kim jonk jong un's economy is in bankrupt. they rely on the smuggling of heroin coyne fit american dollars, fake vying a reinie viagra and weapons. the wealth chelsea football club tainted with a history of racism in its fan base is dealing with a new incident. we have a report from their latest home match.

pressure chelsea is under. this is felt by the fans that those who were accused of racist behavior were not reflect the club. >> everybody is welcome here as long as you are not racist or bgotted. i hope this is the end of it. >> it is a minority of people. >> this is not chelsea fans doing this. not people that are part of our club as far as i'm concerned. i don't want to see it. >> similar sentiments were echoed by the club manager and club captain in the program saying the incident is unacceptable and calling for chelsea football club to come together. the display of unity was evident on the pitch where the fans condemned the behavior. many praised chelsea how

strongly and quickly they reacted but some say the club could do more. >> this with was a horrible, horrible thing that made a lot of people sick to their stomach. i think to be fair most football fans felt sick to their stomach about it. it reminded us of a past we thought we left behind. it showed we haven't left it behind and we to be vigilant about it. >> for them to stop dragging their feet. we say heavy hand. but it serious. they need to get -- when i say punishments direct. it has to be hard and heavy to be honest. it has been light. everybody is being too light. and recurring again repeatedly. where do you go from there? >> reporter: the victim of the alleged abuse is a 33-year-old man on his way home from work

you can see the stronger winds starting to pick up in to scotland and ireland. we are talking wind gusts in excess of 80 kilometers an hour at times. of course that shading of deep red and purples, that is indicating our strongest wind gust as it pushes across paris in to amsterdam, as well as london. you can see copenhagen to oslo this direct northwesterly wind ushering in chilly weather, as well. this cold front does have showers associated with it. this is mainly a rain maker for the region. maybe a few snow showers in advance of it. the main concern here is obviously flight delays. we have potential of an hour to an hour and a half perhaps at amsterdam, dublin more of the same. you can see that is associated to the winds we are anticipating from this particular storm system. now we hop across the big pond. that is the atlantic. this is the united states. and now our eyes focus on the western half of the united states. we are monitoring a low pressure

system that is bringing hefty snowfall to the rockies. great news for skiers and snow boarders heading to the western u.s. look at this. we are expecting pretty significant icing event for dallas texas, south of the oklahoma city area. if you are traveling to this region for business you want to consider this will be a major problem going forward, especially sunday in to monday morning, just in time for rush hour traffic on monday. george? >> more snow goody. >> more snow. >> thank you. a teenager from new york city is headed back home from vacation in hawaii. he's got a pretty incredible story to tell. look at this. the 16-year-old hooked a half ton blue marlin off the coast of the big island. a handful of people spent a half hour reeling in the 1,000 pound fish. the teen says he's been fishing since he was just 2 years old and before this massive marlin

his biggest catch was 55 pounds. new research suggests the strongest material on earth is teeth. >> the common -- unassuming unremarkable until now. inside of these tiny teeth what's believed to be the strongest natural material found on earth. the lied scientist who made the discovery. >> this is the underside and as you can see the mouth there. the limpit has developed a unique way of feeding. it rolls out of its mouth a tongue-like appendage. on the underneath of that are rows of the teeth. straight away you can see the curved shape of the teeth. what the limpit is doing, once

it rolls out this with the teeth underneath it then rolls it back in and these teeth scrape on the surface of rocks. >> reporter: the teeth are made of microscopic fibers about 1,000 times thinner than a human hair and it's these densely packed that give the teeth their record-breaking strength. until now, spider silk was thought to be the strongest material in the natural world. now the limpit tooth has proven stronger. even than many man made materials. >> we spared no expense in testing the strength of limpit teeth. here we have spaghetti and hippo. you are saying that is how strong the teeth are, if it is a spaghetti it would hold up a hippo. >> if we made spaghetti out of the limpit teeth material it would support the weight of the

hippo in the in the demonstration. >> this kevlar here you are sighing it is stronger than that if it were material. >> absolutely. this is a wonderful aspect of learning from nature. >> barber says engineers in fields like formula one may be able to learn from the structure being able to improve the strength of materials while keeping them lightweight is essential for this kind of high-performance technology. a potentially far-reaching application for the rather humble mollusk. max foster, cnn, london. the coveted oscars a few hours away. but those statues have been worked on for months. we have a look inside next. eh, you don't want that one. yea, actually i do. it's mucinex fast-max night time and it's got a nasal decongestant. is that really a thing? it sounds made up. i can't sleep when i'm all stuffy.
