>> hello there, and welcome to this news hour live from doha. coming up this hour. >> i have come to see there is good in every situation. sometimes we just have to look for it. right now that's what we're all trying to do. >> mourning for an american woman who died in isil captivity. u.s. president abraham to call on congress for authorization of force against isil. and new effort to enthe fighting

in ukraine involves a phone call. we all have details. an unique art display that tests the acumen of those viewing the exhibition. the united states has confirmed the death of kayla mueller, the aid work held hostage by islamic state in iraq and the levant. she was captured by august 13th in the syrian city of aleppo. mueller's death was announceed by president barack obama who vowed to hunt her captors and bring them to justice. >> relatives and friend of the 26-year-old humanitarian aid worker struggle with the news of her death. they try to find some

consolation in a parents letter sent to her parents last year. >> she wrote, i have come to see good in every situation. sometimes we just have to look for it. right now that's what we're all trying to do. >> the news of her death was confirmed in a private message from isil to her family. the white house said that it's intelligence agencies verified her death although not the cause or the time. but they also challenged isil's assertion that she was killed in a jordanian airstrike. >> the information that we have is that there is no evidence of civilians in the target area prior to the stroke taking place. that would call into question if the claims made by isil. >> reporter: u.s. secretary of skate johnsecretary of state kerry said that isil and isil

alone is to blame for her death. but isil had demanded and exchange the release of an alleged al-qaeda member now serving an 80 year prison sentence. her parents released a letter to them received last year in which mueller said she had not been mistreated and quote, she had a lot of fight left inside of me, i don't want the negotiations for my release to be your duty. if there is any other option, take it. even if it takes more time. this should never have become your burden. last year a special forces mission reportedly attempted to free hostages, but they failed to find them in the target location in syria. the white house said one other american is believed to be held captive in syria but not necessarily by isil. tom ackerman al jazeera, washington. >> the former director of the cia counter terrorism center.

he join us from washington, d.c. welcome once again to al jazeera. there are reports that the white house will ask congress by wednesday for new authority to use force against isil. what sort of force do you think the white house is planning or hoping to use against isil? might we be looking at boots on the ground? >> well, i don't think the white house is contemplating or expanding the nature of the military effort to isil. i think they're responding from political pressure from both parties in congress that they need specific authority for the hostilities they're engaged in with those areas. >> this pressure from parties before long pre-dates the disappearance of kayla, i don't

think this is part of the equation so far as white house is concerned seeking authorities from congress. >> what does that mean, a more muscular military posture? >> well, as we all know, progress against isis is very very slow on the ground right now. the u.s. is looking for partners that essentially have no effective partners in syria and it has rather weak partners in iraq. and so this is looking to be a very long protracted struggle. there are some voice in the u.s. congress particularly from the republican party, who say we need to take this matter in our own hands. we need to see a greater involvement of u.s. troops on the ground, perhaps to include conventional sources. >> now we saw the killing of the jordanian pilot moaz al

kassasbeh, is there a sense in washington that isil may have overplayed its hand? >> i think they've anticipated the reaction that they did in jordan and we saw the u.a.e. returned marginally from the fight after the death of lieutenant kassasbeh. they've clearly over played their hands and they they risk creating a water shed moment not just in jordan but elsewhere in the middle east. we have not seen that full blown yet with you more atrocities of this sort could very well have that effect. >> thank you speaking to us from washington, d.c. >> you're very welcome. >> well, president obama has called russian president vladimir putin on the phone and urged him to sign a peace deal to end the escalating violence

in eastern ukraine. the white house has warned if russia doesn't, there will be consequences. we have more from washington, d.c. >> the timing from this call for two leaders who have not spoken in a number of weeks is hugely significant. this is not vladimir putin callingbarack obama calling up vladimir putin this is him calling him up about the peace talks in minsk on wednesday. barack obama knows that the damage sanctions have done to the russian economy as he told vladimir putin if there is no peace deal then the russians will continue to pay a price for the ongoing violence. he's talking about increased sanctions both from the u.s. and also from the european union.

there was no talk providing defensive weapons to the ukrainian army, although barack obama is under increasing pressure domestically to do just that. he said to vladimir putin look, we want to deal. if you don't do a deal at the very least you're going to pay for it financially in the short term. >> well, putt someone on a diplomatic offensive as well. he just finished his two-day visit to egypt his first in ten years. the russian president has been holding talks with his egyptian counterpart on a number of key issues. and he had a special gift for his russian host. >> when your adversaries are trying to isolate you internationally, go visit your friends. egypt rolled out the red carpet for vladimir putin. this is a relationship that suits both men very well at the

moment. >> we have confirmed that we're standing side by side in our challenges and the spread of wicketness that the whole world is suffering from. >> tourism investments the two-state solution for the palestinian problem military cooperation and russian assistance for egypt's nuclear power ambitions. >> when we reach final decisions we'll build a nuclear plant and create a new sector in the egyptian economy. the two men had spent monday night at cairo's opera house. a personal relationship has developed from previous meetings meetings. >> this visit is more about optics than anything else on the surface. we're looking at two embattled figures. with economic problems in

particular because of the oil prices with russia and the sanctions of course. >> egypt's president is re retreading ground his predecessors also walk. for much of the 20th century, egypt played russia and the united states against each other for its own relationship. and el-sisi has not yet forgiven the united states for support of the morsi and muslim brotherhood and criticism of his own presidential crackdown. but like his predecessors, he's trying not to shut any doors. he made sure to say that egypt is sure to have relationships with all countries it respected. this may be russia's hour, but egypt likes to keep its options open. >> at least two 21 people have been killed after a rocket attack deep in ukrainian controlled territory. it comes on the eve of talks

being held in minsk. al jazeera's charles stratford reports. >> destroyed ukraine ukrainian tanks and heavy weapons in the snow this town is virtually deserted. fighters with the self proclaimed army of the donetsk them' republic took control from the ukrainian army a few days ago, and they say they're advancing, tightening the noose around the important town of deabesv. >> it is important. people here believe in us. they voted for news a referendum because they trust us. we want to bring them freedom. >> it's not known how many civilians were killed here. this is a town around ten kilometers as the crow flies and it was taken over by the separatist as few days ago. we're hearing outgoing shelling

and the separatists have told us that they have the city completely surrounded. >> ukrainian army denied the claim, but the day before we were cross the front line and we saw ukrainian tanks digging in in the only route in the city. the rocket launchers were driving towards the front. missiles hit a residential area, and military base. >> we were feeding the kids. they were sitting at the tables. the kids started screaming and the shells started to explode. it was judgment day. we started to round up the kids in groups and tell them fairy tales. look kids, it's just thunder in the middle of winter. >> the ukrainian authorities

said that missiles had been fired from the separatest town. in. >> in front of you now is where the weapon landed. it flew from the southern direction. >> the area is home to the ukrainian's command. the separatists denied the attacks. in a separatest base we find this ukrainian army prisoner. they cover his burnt face. his tank was hit in the battle. outside hang the pictures of dead separatest fighters, and a father grieves for his son. >> of course i'm proud. he was defending his motherland, his people, his family. as yet another attempt of cease-fire talks is scheduled for wednesday. sons and daughters continue to be killed in the violence here every day. charles stratford al jazeera,

eastern ukraine. >> joining us now from washington, d.c. is william taylor, a former u.s. ambassador to ukraine and currently the acting vice president of the united states institute of peace. welcome to the program sir. so president obama calling-- >> thank you. >> --president putin on the phone, asking him to agree to the peace deal. how will this have gone down with president putin. will he agree with it, do you think? >> president putin finds himself in a tight spot. his economy is under great pressure and that's starting to affect the people of russia, who are paying the price for mr. putin's adventure invading ukraine. mr. putin is starting to pay a political price. he's also, as your reporter said there are russian soldiers dieing in ukraine, and that's causing a problem for him as

well. it might be that mr. putin is looking for a way out, and this phone call could have indicated from him, from mr. obama to mr. putin, that the pressure can only get worse if mr. putin does not take this last chance to move back. >> a white house statement warns that if russia does not sign this deal there will be consequences increased sanctions, perhaps against russia. but no mention of potential arming of the ukrainian forces that the u.s. president is considering. >> the united states is considering providing lethal weapons to the ukrainians. this would give the ukrainians the ability to push back and defend themselves from the invasion from the russians. this is another factor for mr. putt on it consider. again, when russian soldiers die and more will die if he continues this adventure this, invasion if the ukrainian military has more advanced

weapons, that's the result. >> now president obama is at pressure at home. he said he's still undecide. the conflict continues to escalate. what are your thoughts. >> if the russians escalate the conflict, they are very clear that they're invading. the russians continue to deny that they're in eastern ukraine when the rest of the world knows knows, can see and there is evidence that they're there in their military forces. if they escalate in response to the ukrainians, defending themselves then it will be clare for all to see and the next step of economic sanctions will be--will go into affect. >> ambassador, if you could just before you go, why is president obama under so much pressure at home to arm the

ukrainian forces? is this about more money for weapons manufacturings or really just tackling the ukrainian crisis. >> i don't think it has anything to do with money and manufacturing. i think it has everything to do that the russian attack on ukraine is an attack on the whole international security system that has been in place since world war ii, and certainly since the end of the cold war. that attack puts all nations in europe in jeopardy. the united states wants to do what it can to support our crane in this attack. >> thank you very much for speaking to us. william taylor, former ambassador to ukraine. >> thank you. >> we have loots more ahead this hour. >> celebrations in deli as an anti-corruption party. and why businesses and the

government in venezuela blaming each other for food shortages. >> i've heard that, i'm concerned about it, and i want to guarantee that that does not happen in the future. >> and in sport find out what this fifa presidential candidate has told al jazeera i'll put an end to if he takes control of football. >> a verdict is expected on wednesday in a belgium court in the mass trial of 46 young muslims accused of joining isil in iraq and syria it comes at a time of increasing concern. were brussels, simon mcgregor wood has more. >> reporter: only nine appeared to "n" court. the rest are thought to be fighting in syria or iraq or died there. prosecutors allege most were

recruited by a group called sharia for belgium. it's recruited dozens of recruits mostly of moroccan descent. the belgium authorities want this high profile trial to send two signals: to discourage others belgiums from going to syria and let them know if they do they'll face prosecution and time in jail if they return. not the best way to use the law according to some. >> so the more the establishment will pro poems repressive policy, the more you confirm that the young people in counter culture have arrived. >> how to prevent more

recruiting and stopping attacks on domestic soil. >> we're not focusing on the oppression response. we think building on the movement and promoting values in society is equally important. >> belgium's recent experience suggests that the threat is real enough. back may a fighter killed four people in brussels jewish center. the area is surrounded by barbed wire. tensions are high. wednesday's verdict may set a harsh example at may discourage some, but it won't do anything to rebuild trust. simon mcgregor wood,

he'll feel bolstered domestically. he got 162 votes out of 300 members of parliament, so his coalition rallied around him and he'll go into a series of vital talks with european leaders starting later this week saying to them, look, i have a mandate from the greek people. i have a mandate to increase social spending to cut taxation on the poorest people in our society, to raise pensions, to raise the minimum wage. all of these, he says, are intended to end what he describes here in greece as a humanitarian crisis. >> the family live where a similar light connected to the neighbor's electricity supply. their own cut off when they didn't play the bill. unemployed for five years.

democracy will come back to greece and to us. >> but who is going to pay for all this? economists warn without help greece could run out of money within weeks. >> it seems that the government have promised a lot of help. >> in my view i do not think that all the fiscal costs of what the government has promised can be met with. >> the port, the previous government promised to privatize it but they say the port will not be solved. >> this would an major statement of a new direction of economic policy and it would have repercussions. the greek relationship with

reproduce 5 replicas every year. what is art? what gives it it's value? philosophers have been question questioning that for millennium. >> a work of arrested is not just an appearance. it's the product of someone's effort skill and technique and originality. >> it's good to have a show like this because increasingly art is becoming an asset in the hands of the world's 1%, along side their stocks and bonds. so a show like this really makes you look at the picture and see it for its beauty rather than its price tag. visitors have until the end of april to register the one they think is made in china. after that the copy and the original will hang side by side, and the public can decide what is art. jessica baldwin al jazeera, london. >> what a great idea. we'll have more news for you in just a few minutes. bye for now.
