it was the devastating news her family feared most. >> plus shocker at nbc. news anchor brian williams is taken off the air for at least six months. and comedian jon stewart says he's signing off from "the daily show." >> hello and welcome to our viewers in the united states and all around the world. appreciate you being with us. >> we have a lot of coverage to get to tonight, especially about brian williams the nbc news anchor who will be off the screen for at least six moments. but we begin with the u.s. aid

worker who were held by isis. isis sent them a private message, authenticated by u.s. intelligence confirming kayla mueller is dead. >> the message included a photo of her wrapped in a burial shroud. >> reporter: kayla mueller's parents received word of her death in a message from isis that included photos confirming her death. what is not known is how she died. late today, her aunt remembered a caring courageous young woman. >> her calling was to help those suffering, whether in her hometown of prescott or on the other side of the world. she's done more in her incredible 26 years than many people can ever imagine doing in their lifetime. >> reporter: while in captivity, she sent a letter to her parents that reads, in part if you could say i have suffered it all throughout this experience it

is only in knowing how much suffering i have put you all through. i will never ask you to forgive me, as i do not deserve forgiveness. she worked with humanitarian groups in india, israel and the palestinian territories. and by 2013 she was already in turkey helping syrian refugees. she posted this in 2011. >> i reject the brutality and killing that the syrian authorities are committing against the syrian people. >> reporter: on august 3rd 2013 she entered syria, traveling with a young man believed to be a syrian and described as colleague, boyfriend or fiance. he went there to fix the internet connection at a hospital. kayla apparently joined him on a trip to a war zone off-limits to americans. the two stayed overnight. but the next day, returning to turkey both were grabbed on the road. mueller's family didn't hear from isis for nine months. in may 2014 their first

message, proof that mueller was alive. two months later, a ransom demand, about $7 million or kayla would be killed. that deadline passed with no further word. in the letter to her parents, mueller talks about how isis treated her. please know that i'm in a safe location, unharmed and healthy. put on weight in fact. i have been treated with the utmost respect and kindness. isis claims mueller was killed in this building by a jordanian air strike. but today, a white house spokesman placed the blame for her death squarely on isis. >> this is the organization that was holding her against her will. that means they are responsible for her safety and well-being and they are therefore responsible for her death. >> reporter: we know the president has spoken by phone with mueller's parents. he sent his condolences and commended kayla's selfless work and pledged to relentlessly pursue those who had a hand in her death. priority one is to bring her body back home so this

community, her family can have closure and kayla can rest surrounded by those who love her. >> and there is so much anger here in the united states about kayla mueller's death. u.s. president barack obama has vowed to bring the terrorist responsible for mueller's death to justice. >> after her death was confirmed, mr. obama told buzz feed about a risky operation he ordered to try to free the aid workers, the other isis hostages. >> my immediate reaction is heartbreak. i have been in touch with kayla's family. she was an outstanding young woman, had a great spirit. i think that spirit will live on. the more people who learn about her, the more they appreciate her and how it stands in contrast with the barbaric organization that held her

captive. but i don't think it's accurate to say that the united states government has. done everything that we could. we devoted enormous resources and always devoted enormous resources to frame captives or hostages anywhere in the world. and i deployed an entire operation at significant risk to rescue to the only her, but the other individuals that had been held and probably missed them by a day or two, precisely because we have that commitment. the one thing that we have held to is a policy of not paying ransoms with an organization like isil. and the reason is once we start doing that not only are we financing their slaughter of innocent people, and strengthening the organization

but we're making americans even greater targets for future kidnappings. >> as barack obama mentioned, problems are getting worse. u.s. intelligence officials say that isis may be looking to capture more western hostages and they could be planning operations in lebanon and in turkey as well. >> this comes amid growing concerns about the number of foreign fighters joining the terror group. jim sciutto has the details. john cantley is one of the last western hostages held by the terror group. james the others dead while in isis' hands. now new concerns they may try to abduct foreigners outside of syria. >> it would be easy to go up to these refugee areas, target a

werner whether journalist or aid worker and try to conduct a kidnapping within the area of those refugee catches andmps and just pull them back into syria. >> reporter: while warplanes continue to strike the syrian president said he would not stand in the coalition's way. in an exclusive interview, assad hinted at limited cooperation, saying his country receives information about u.s. operations over syria via third parties, such as iraq. >> that's through a third party, more than one party. sometimes they convey the message, general message. but there's nothing tactical. >> so they don't tell you we're going to be bombing raqqa at 10:00 this evening, keep out of the way. >> we knew about the campaign before it started, but we didn't know about the details. >> reporter: the pentagon denied any communication. >> let me try to be real clear

here. they're not communicating or coordinating our military operations with the assad regime. we're not doing it directly and we're not doing it indirectly. >> reporter: a senior u.s. intelligence official tells cnn that the number of foreign fighters in iraq and syria is now more than 20,000. up from 16,000 in november. despite efforts by neighboring countries to stem the flow of militants. a new isis manual tells potential recruits how to evade detection when crossing the border. avoid looking nervous, rapid breathing, cold sweats and lack of eye contact can be detected by trained security officials. and there may be guards on the long syrian-turkish border. look around. if the coast is clear, run as fast as they can into syria. jim sciutto, cnn, washington. u.s. lawmakers are preparing for what could be the first war vote in congress in about 13

years. they'll soon hear details of president barack obama's request for authorization to use military force against isis. even though american warplanes have been targeting the militants since august under authorizations past after 9/11. the new measure would be limited to three years and focus solely on combatting isis. it lawmakers are already expressing concern over what role u.s. ground troops will play. let's turn now to breaking news we've been following in the united states. the nbc television network has suspended one of the most influential news anchors in the united states for six months without any pay. and considering he makes about $12 million a year -- >> more like $10, but close. >> the news comes after brian williams admitted exaggerating a

story about an ire war mission he was on in 2003. >> in a statement, nbc universal's ceo says williams' actions are inexcusable, but he deserves a second chance. the weekend anchor lester holt will fill in for williams during the suspension. but the big question can brian williams come back from all of that? we're joined now from los angeles. matthew, thank you very much for being with us. that is the question six months is a long time to be out of the public eye. do you expect brian williams to come back six months from now? >> that's the big question everyone is asking. i do think he will be back. i don't know it will be such a face of the network role but i do think he will be back. these days six months is a long time but it's a long time for people to forget. laura logan was suspended by cbs for a faulty report and she's

back on that network. i think brian williams does have a chance but there are those that believe this six-month period is to allow them to negotiate a proper exit and have a replacement there for him. >> let's take the other side of the weekend, brian williams didn't kill anybody or go on the air and deliberately lie, i guess. he embellished a story. a little closer to the action than he really was. in the grand scheme of things is this really a hanging offense? >> the only currency that networks have is their credibility, as you know. once that credibility question comes into play and people don't trust you, what's your value? so at this point, they're saying does brian williams have any credibility left? and if he doesn't, how can they make him the face of nbc news? >> why have none of his peers come to his defense in >> that's a good question. some people have said nice

things and have said you know, he deserves a second chance or they want him to rehabilitate himself. i know bill o'reilly has come to his support, megyn kelly and brit hume on fox news said they want to see him survive this. but there hasn't been an outpouring of support at nbc universal that. speaks to the level of embarrassment it's caused the network. >> and one big problem for nbc news is they don't have a replacement. they're going to park him here for six months and if they can get somebody else to sit in the chair maybe he's gone. maybe he's an insurance policy in case lester holt doesn't work out. >> we've heard everything from savannah guthrie, perhaps jon stewart might be interested in moving over to do real moves from fake news. all options are on the table at this point. but i don't know that they have a plan. i think they're just starting to figure out what they might do if they don't bring him back.

keep in mind this investigation is still ongoing. they could find other embellishments in this investigation that could basically mean the end for him. >> if you look at nbc news gosh just a few years ago, they were riding high the crown jewels in the nbc network. they've taken some hits and they could have done without this. >> if you look at every one of nbc new's franchises from the "today" showy lost its crown to "good morning america," cnbc now they have to worry about "nightly new ss." >> matthew, we appreciate you being with us giving us perspective on what's going on over at nbc. >> as a network anchor the only credibility you have -- the only currency you have is your credibility. if you lose that --

>> i just wonder if there wasn't the all-out attack which is going 424-7 would it have been that big a deal? and jon stewart announcing he will leave "the daily show." he's hosted the show for more than 15 years. stewart talked about his decision to step down just a few hours ago on tuesday's show. >> it's been an absolute privilege. it's been the honor of my professional life and i thank you for watching it for hate watching it. whatever reason you were tuning in for, it -- you get in this business with the idea that maybe you have a point of view and something to express and to

receive feedback from that is the greatest feeling i can ask for. and i thank you. >> great show to watch, but not so fun if you're being made fun of. i've been on that show a few times, but fortunately he has not made fun of me. but comedy central hasn't said when stewart will be signing off, but it could happen as soon as this summer. >> maybe he'll take over for brian williams. >> maybe. >> who knows? we'll take a short break. when we come back, leaders begin to gather for peace talks in ukraine, a key town comes under heavy fire. plus "the american sniper" film has captured the attention of millions. now many people will be focused on a real-life murder trial connected to the fill. that's coming up after the break. i'm looking forward to. for some every dollar is earned with sweat, sacrifice, courage. which is why usaa is honored to help our members

peace. >> the call came just hours ahead of a planned -- ahead of planned peace tucks between vladamir putin and the leaders of ukraine, france and germany. the meeting will take place in belarus, where delegates have already begun preliminary talks. >> the violence in ukraine continues to get worse. fighting is continuing with heavy shelling reported inand another strategic town is now under fire. >> reporter: this is what eastern ukraine sounds like, hours before peace talks. the target in the distance. through that distance haze is the key access road into the city the separatists claim they have cut off and taken. that sound is of the constant shelling and at times you can

hear small arms fire. clearly the fight for that town under way. snipers testing their aim. and down one lane a unit of front line separatist troops. a local policeman we recognized from months ago. yet flying hear the official flag of the russian airborne division. did these modern tanks also come from russia? they pushed out across the fields to this the main road we had traveled down a week ago. as peace talks looked imperilled rockets slammed into the otherwise ukrainian up to killing several and wounding dozens. on the military base nearby many believe was the target. the violence spirl ingaling,

dizzying. nick paton walsh, eastern ukraine. let's turn to another story we're following in the us. the high profile american sniper trial begins. a look at how the movie can complicate the real-life case. six feet and counting of snow for boston. i have a cold with terrible chest congestion. better take something. theraflu severe cold doesn't treat chest congestion. really? new alka-seltzer plus day powder rushes relief to your worst cold symptoms plus chest congestion. oh, what a relief it is. here we go! flo: hey, big guy. i heard you lost a close one today.

look, jamie, maybe we weren't the lowest rate this time. but when you show people their progressive direct rate and our competitors' rates you can't win them all. the important part is, you helped them save. thanks, flo. okay, let's go get you an ice cream cone, champ. with sprinkles? sprinkles are for winners. i understand.

a new york city police officer has been indicted in the shooting death of an unarmed man. he died from a sing t shot to the death. the incident happened in november. >> at the time the nypd said the shot was accidental. officers did not reveal the charges against the officer peter yang. he had been on the job, show less than a year and a half. opening statements begin just hours from now in a trial of a man charged with killing the former navy s.e.a.l. whose story was told on "american sniper." eddie ray ralph is accused of killing chris kyle and kyle's friend at a texas gun range. we get details now from martin savidge. >> reporter: at the movie theater outside stevenville, texas, just like anywhere else you can catch the film "american sniper." the hit movie that focuses on navy s.e.a.l. chris kyle.

but unlike anywhere else in the center of sown at the courthouse the focus will be not on how kill lived but how he died. as many as 800 jury notices went out. despite that number jury selection ended a day early. ten women, two men, all white, and two alternates. each one of them had to fill out a four-page questionnaire, asking things like where they work if they know the accused, or the two victims, kyle and chad littlefield the other man murdered with him. they're also asked about military service and question number 14 -- have you read the book listened to the audio book or seen the movie "american sniper"? answering yes did not get you disqualified but it shows how the movie has complicated the case. but in the courtroom, the characters are real and all eye also be on former marine eddie

ray, two servewho served in iraq. he confessed to his sister. >> my brother came by here and said he committed a murder. >> who did he say he killed? >> he says he killed two guys at a shooting range. he's all crazy. he's [ bleep ] psychotic. >> reporter: but he entered a plea of not guilty. his attorneys will made innocent by reason of insanity due to post traumatic distress. expect both sides to produce plenty of medical documents. a single video will be allowed to shoot through a window. but in an unusual move the judge ordered after opening statements to be no audio from the courtroom. which is unfortunate, since the

trial will very much have movie-like drama. the first witness expected to be called is the widow of american sniper chris kyle. martin savidge, cnn, stevenville, texas. we want to give you news on another trial, massachusetts prosecutors have granted immunity to aaron hernandez's fiance forcing her to testify as a prosecution witness against her ex-boyfriend. prosecutors believe she hid or destroyed the gun used to kill odom lloyd. she was accused of lying about evidence and conversations with hernandez. lloyd was gunned down in a field less than a kilometer from hernandez's home. the murder weapon has still never been found. parts of the u.s. northeast are seeing more snow than ever before. boston seems to be experiencing

a new ice-age. six meters of snow in the last month. and eastern massachusetts is running out of places to put it. there's so much snow that they will dump it in boston harbor. >> and there's more bad weather on the way. as john mentioned, six feet of snow, 17 days. it's incredibly cold there, as well. >> 36 is the number how many days left until spring begins. looks like another storm is going to push in here. remarkable of the amount of snow that we are seeing. as it pushes off to the northeast, we expect less snow than the models initially indicated 4 edd 24 hours ago.

this is thursday night into friday morning, the storm pushes just offshore. it looks like some moderate to heavy snow in the forecast. the american model wants to bring it closer to land but they're not far apart from the european model. so better agreement they're both going to go out towards open waters, bringing in some snow. up towards cape cod, 4 to 6 inches expected. it was 12 plus inches the initial model indication about 4 hours ago. the other model that brings in similar amounts, about 2 to 4 around boston putting new york out of any major accumulations, maybe just one inch at the very most. but this is what is on the ground. the snow depth over two feet over boston southern new york about eight inches on the ground around central park. we touched on how much snow is

in place. in massachusetts, you could fill up the football stadium 90 times with the amount of snow they've plowed in recent days. this place, the piano store here, this piano worth $500,000 once owned by liberache. damage there done not to the piano. it is dotted with nearly 90,000 rhinestones, but significant damage to the roof and parts of the building. we'll take a short break. when we come back we'll talk about kayla mueller, the aid worker killed by isis. we want to find out how she lived, and not how she died. police in sydney arrest two men they say were planning an imminent terror attack.

what evidence investigators say they found. that's coming up. really... i guess i did take some risks. anncr: bode, bode miller!!! trained a little bit differently. a little too honest sometimes. the media is useless. you were out of control. but not always. sir, we're going to need you on the runway later. don't let a severe cold hold you back. get theraflu... ...with the power of three medicines to take on your worst pain and fever, cough and nasal congestion. it breaks you free from your toughest cold and flu symptoms. theraflu. serious power.

just after half past the hour. you're watching cnn. i'm john vause. >> and i'm zain asher. nbc has suspended brian williams for six months without any pay. the move comes after williams admitted exaggerating a storey about an iraq war mission he was on back in 2003. lester holt is going to be filling in for williams during the suspension. jon stewart says he's leaving his hit show "the daily show," later this year. he's hosted that program for more than 15 years.

no word on when stewart will sign off, but it could happen as soon as this summer. u.s. president barack obama phoned vladamir putin on tuesday to address the violence in eastern ukraine. he urged the russian president to seize the opportunity for peace. the call came just hours ahead of planned peace talks between mr. putin and the leaders of ukraine, france germany, as well. preliminary talks in belarus have already begun. let's get straight to a story we've been following all tay today. a tragic story. a u.s. official says it was a photo of american aid worker kayla mueller in a burial shroud that convinced them that the isis captive had, indeed been killed. the news left her family and friends just devastated. >> and they're now remembering her as a free spirit. >> kayla has touched the heart of the world.

the world grieves with us. the world mourns with us. the world wants to be more like kayla, and if that is her legacy and the foot print that she leaves on the world, then that is a wonderful thing. >> i do know that we're all living in a better world because of her. so i'm going to end on a quote that reminds me of her. peace is not something you wish for, it's something you make. it's something you do. it's something you are. and it's something you give away. >> impossible not to be moved by that. but as mueller is mourned at home condolences and tributes are pouring in from across the country.

>> for more now, here's pamela brown. >> reporter: the family of 26-year-old american hostage kayla mueller said today they have received confirmation that their daughter is dead. u.s. officials say kayla's isis captors sent the family a private message, including pictures that were used to verify her death. >> they're taking a look at the actual evidence that's been supplied and they're comparing that with intelligence that they've got and clearly with the factors they're looking at they feel like kayla is in fact deceased. they're stopping short of saying isis murdered her, but one way or another, isis is responsible. >> reporter: the information does not clarify how and when mueller died though isis claims she was killed in a jordanian air strikes last friday. at the time, it offered no proof other than these images. today, the white house made it

clear isis is ultimately responsible for her death. >> the information that we have is that there is no evidence of civilians in the target area prior to the coalition strike taking place. and that certainly would call into question the claims made by isil. >> reporter: she was helping syrian refugees on the turkish board, but what brought her to aleppo remains a mystery. the mueller family today released a letter kayla wrote in the spring of 2014 while in captivity, saying "if you could say that i suffered it all throughout this whole experience it is only in knowing how much suffering i have put you all through. please know i'm unarmed and healthy, put on weight in fact. i've been treated with the utmost respect and kindness. she signed the letter all my everything, kale la. >> the letter was written under duress and at the same time i wouldn't be surprised if a lot

of that was true. my guess is that she was such an incredible strong spiritual, respectful person that she actually caused them to treat her the same way that she treated them. >> reporter: pamela brown, cnn, washington. >> another story we're following out of the middle east israeli prime minister netanyahu says he has a pro-found disagreement with the u.s. on nuclear talks with iran. the speech is controversial, because a top republican leader issued the invitation without the knowledge of the white house. >> i'm going to the united states not because i seek a confrontation with the president, but because i must fulfill my obligation to speak up on a matter that affect it is very survival of my country. >> netanyahu says congress might

have a role in the nuclear deal. some lawmakers favor imposing more sanctions on iran a move president obama opposes. police in sydney australia have arrested two men for planning terror attacks for incidents overseas. anna coren joins us live now from the capital. what do we know about this alleged plot? >> reporter: we know that police raided this home in fairfield yesterday, just after 4:00 p.m. and arrested these two men, age 24 and 25 charging them with terrorism. police believe that an imminent attack was about to take place. they seized a machete, a hunting

knife, an isis flag, as well as a video recording. let's now take a listen to what deputy police commissioner catherine burn had to say. >> we believe that attack was going to occur yesterday. one of the items that will be introduced into evidence is a video. and in that video, we will allege that one of the men end camed that an attack was going to be carried out. >> reporter: the deputy commissioner talked about this violent act. she's asked whether a public beheading had been planned. she wouldn't be drawn into that. of course, that is the fear. there were numerous terror raids conducted in australia last year. and two months ago, there was that sydney siege, which a crazed gunman who sympathized with isis took 18 hostages. two of those hostages died.

but the terror attack obviously placing australia very much on high alert as the threat is very real. >> do we know with relation to these two men who were just arrested were they allegedly inspired by isis or instructed by isis? >> reporter: we don't have that information at the moment. what we do know however, is they were not known to police. that is what is extremely alarming here. police receiving a tip-off from a member of the public which is what caused them to raid that home in sydney. the prime minister here speaking about it earlier, saying that he's concerned that things are going to get worse before they get better. john? >> anna, thank you. switching gears now. still to come on cnn, they come

from two very separate wells, but they've been sharing the headlines the past couple of hours. we'll be telling you about one on a temporary hiatus and the other's permanent farewell. my name is michael. i'm 55 years old... and i have diabetic nerve pain. the pain was terrible. my feet hurt so bad. it felt like hot pins and needles... coming from the inside out of my skin. when i did go see the doctor and he prescribed lyrica. it helped me. it's known that... diabetes damages nerves. lyrica is fda-approved to treat diabetic nerve pain.

months without pay from nbc. that's after he admitted embellishing a story about an iraq mission he was on in 2003. >> you have that, and then now jon stewart saying he is quitting "the daily show" later on this year. here's what he had to say about his decision to step down just a few hours ago. >> i'm not going to be here and try and sum up what this place has meant to me over the years, but i couldn't do that and we have plenty of time and i have a myriad of people to thank. i'm not going anywhere tomorrow. but this show doesn't deserve an even slightly restless host and neither do you. >> now brian williams suspended

without pay for six months. has anything like this ever happened? >> there is no precedent for this and many people don't believe williams will ever come back now that he'll be going away for such a long period of time. this is a severe suspension but i'm not sure nbc had any other choice. they had to impose some harsh penalty, given the tall tales williams had been telling about an iraq war mission in 2003 and then hurricane katrina and the aftermath of that storm. so nbc had to do something, and perhaps the only other choice was to remove him entirely. i'm told his name will be removed from the program while lester holt fills in. and you have to wonder if he will return or not. >> can he come back after six months as if nothing happened

is that possible? >> i suppose anything is possible but he has to regain people's trust and credibility. that's not going to be easy to do when he's sitting on the bench. >> i also want to talk about jon stewart stepping down from "the daily show." i know that his contract was up this year. how much of a surprise was this really? >> the report is the end of fake news and the end of real news tonight. it's been remarkable to see brian williams forced to have a suspension and jon stewart voluntarily stepping down. they come from two different worlds but there are some similarities between the two. brian williams has been on jon stewart's show many times. he might be the most frequent quest on "the daily show." they're also known to be friendly. so there was speculation that maybe some way, somehow brian williams might move over to fake news might move over to a more comedic format. it's almost too perfect to be true to have these announcements

come within an hour of each other. but jon stewart's contract was coming up later this week. he had been talking openly for a while about deciding to try something new. 16 years is a long time to do any one thing, especially if you're making fun of the news and politicians every weeknight. so now the question is what will comedy central do with the show? it's a famous show. it's a format that cnn international used to show around the world. and the show will continue in some form, we just don't know who will be hosting it. >> jon stewart, a man of many talents, also as a director as you saw last year with his film "rose water." so explain what his legacy will be. young people get their real news from "the daily show." remarkable. >> jon stewart pioneered some of the formats that he uses on his program, the way that he splices together video and audio clips

to make a politician or a cable channel like cnn look bad, that's a tactic we see used online and youtube. but it began with jon stewart's show. it's been able to mine the archives of the web and databases to find interesting material and to string stories together. sometimes he'll do a ten-minute monologue that presents quite a lot of news in it. but in a comedic fashion. we've seen others try to take what he started and grow with it and learn from it. john oliver now has his own show where he's improving on the form of satirical news. so what jon stewart started, many others are following. we'll see stephen colbert take over for letterman this year another example of someone following in jon stewart's footsteps and figuring out ways to get young people's attention and interest in the news in a way that traditional news casts
