hopefuls take to the stage for the second time u i.s.i.l. and foreign policy dominate the gate. we begin in france where prosecutors have been revealing details about the gunmen and suicide bombers who carried out a series of deadly attacks across paris on friday night. 129 people were killed and more than 350 injured. 99 of them critically. prosecutors say the highly coordinated operation which has been claimed by i.s.i.l. involved a multi national team with links to the middle east, belgium and possibly germany. belgium police have arrested several suspects with alleged links to the attacks. greek officials say one or two of the attackers passed through greece from turkey alongside syrian refugees. some of the attackers also have french roots. one of them was a 29-year-old

paris native. his procedure and father have been taken into custody. more from paris. >> reporter: the memories of the brutal attacks still all too raw as people came too stand vigil over night in tribute to those who lost their lives. prayers too for the lives surgeons in the city's hospitals are still fighting to save. nearly a hundred victims are on the critical list. the message here, though, we are not afraid. >> translation: there's a lot of emotion for people like us after all that has happened. a lot of sadness, hatred as well for those who come and attack us when we are quietly getting on with our lives. >> translation: two weeks ago a friend of mine said don't go to tunisia. it's too dangerous. i said it's the same here.

>> reporter: these men were cold hearted professional killers. they were all armed with automatic weapons and they knew how to use them. they also all had suicide belts with detonation buttons. they had ball bearings to extend the killing and maiming of those suicide vests. >> translation: we can at this stage say it's very likely that there were three coordinated teams of terrorists who were responsible for this barbaricity. the perpetrators need to be found, who ordered them, their route and who financed them. >> reporter: the police say there were seven known attackers all dead. they have positively identified one, a french citizen whoa tabbed the concert hall. he was on their extremist watch list but had only been involved in petty crimes. his father and brother are now in custody. several men have also been

arrested in belgium and police say they're connected to a car found near the concert hall. another piece of evidence was sdovrtd at the stade de france. a syrian passport was found near the bodies of the suicide bombers. it was used by someone claiming refuge on the greek island of leros in october. eau motions are still running high here. i.s.i.l. has unleashed such carnage in beirut and baghdad, but now it is a water reaching into france going to paris. neve, details coming about who is involved and what happened. where is the focus now? >> reporter: it's early morning here in paris. the second day of morning. that's perhaps where the focus is for more people focusing on exactly what happened here in

coming to terms with what is deeply traumatised this city. over night mounting attributes here. the authorities have urged people not to gather in large crowds. there is a perceived security risk and some areas are, indeed, still active crime scenes. as you mentioned there, the investigation into the attacks continues with the french prosecutors, investigators making their understanding of what has happened here known to the public. some of what we said they already know, that there were seven attackers, that they operated in three separate groups but they were heavily armed with weapons and studies belts. we also know some extra information too, that this is now an international

investigation. it has gone beyond france's borders. it has been viewed as a complex cross-border operation involving people also in belgium where three arrests were made by police there in the last 24 hours. also in germany where last week german police arrested a man in a car in bavar arcs a with weapons inside that car that they believe now was directly linked to this attack here in france. also some other key information about the identitys of the killers. first, a killer was identified through a fingerprint in the bataclan concert hall a little bit further down the road from here. he has been identified as a french national from a rough and tumble suburb of paris on the fringes of the french capital. he has been named. we know that his brother and father have been arrested also. we also know that according to

forensics teams who are looking at the site of the explosion in the stadium in the north of the city that a syrian passport was recovered from the remains that were found there. although, according to reports this morning on french television, they believe that that syrian passbook could well be a fake. weep have to establish whether or not that is the case over the course of the day, but according to greek officials, whoever was using that passport may have travelled through greece heading to europe. this adds a whole new political dimension to all the security questions that are being posed at the moment. of course, if this was indeed a syrian national, was this person a refugee? that very much place into the rhetoric into france's white ring officials who feel the french borders should be tightened and whether or not, of course, this was a french national who was involved in carrying out and orchestrating

this account. that raises questions of home-grown risks in france and what essentially the french authorities can do about it thank you for that. there has been, as you can imagine, outpouring of global support for parisians. hundreds of people held french flags in front of the whit house. flowers were laid down and condolence messages were left. president obama described the attacks an outrageous attempt to terrorize civilians. people gathered at the french german cultural center to show solidarity with the people of france. the statue was lit up in french national colors. here the stadium in the south was also lit up in red, white and blue. french prime minister says it is impossible to eliminate the risk of terror attacks completely.

he says air strikes on syria will continue. >> translation: there is no such thing as zero risk. on january 13 after the paris attacks against "charlie hebdo" do against the french people because they were jewish, against law officials, i said we were at war and i said this war will be long and difficulty. we need to expect after shocks, but we will retaliate and destroy d.a.e.s.h. present president has promised to lead the fight against i.s.i.l. a look at the attacks on french politics. >> reporter: paris under attack again. this time with more sophisticated and deadly effect. the president has called it an act of war. >> translation: faced with war, the country has taken appropriate steps. it's an active war committed by

a terrorist army d.a.e.s.h., an islamist army against the values we hold throughout the world, against australia free country that speaks to the whole planet. >> reporter: this was the speech to do with upcoming elections. >> translation: islamic fundamentalist must be destroyed. france must be that as it may islamist organisations, close radical mosques and illegally legal immigrants who have nothing to do here. >> reporter: friday's killings were claimed by i.s.i.l. or d.a.e.s.h. in a statement it blames french foreign policy. >> we decided to hit eye i.s.i.s. in iraq and not a long time ago we decided that was self-defense to go into syria. it's a turmoil we are in now. >> reporter: in other words, does it surprise you that france has been singled out for these kinds of attacks?

>> not much. >> reporter: the government has the army onto the street but questions will be asked about its preparedness before these attacks. >> reporter: things have evolved into much more disturbing manner than i think anybody imagined. the french were expecting something fairly big. the background noise was sort of evil over the last two weeks. but it is the sheer sophistication of this attack, of the series of attacks, which really does strike one. >> reporter: the streets of paris have been stunned into an eerie quiet, a country in a state of emergency wondering why this is happening again so soon after the attacks on "charlie hebdo," journalist and jewish shoppers in a supermarket. after the january attacks, people and world leaders gathered, france stood united with allies in defense of its

freedoms. now such gatherings are banned. this feels like a more fractured defensive france, a president promising to defeat the enemy, a nation of deep disquiet the e.u. foreign policy chief says finding a solution to the price crisis in syria has taken on a new meeting because of the attacks. talks have been made in vienna with an agreement on a tame table for a cease fire. one says the timeframe for a planned election is too ambitious. >> translation: crisis that has been ongoing has opened the wound for the past five years is one that the international community has been trying to crisis manage instead of resolve. it would be difficult to achieve a solution within a year and a half. i think we need more time than that. i think that to resolve the issue, if there is seriousous

and mistrovato, in order to succeed we will need two to three years world leaders are opt anies particular that elections can happen in 18 months. the push for political solution is stronger than ever. >> reporter: while the tacks in paris may have over shadowed saturday's talks about syria, they also underscored a new diplomatic commitment to end that country's war. >> make no mistake, that resolve has only grown stronger in the wake of this unspeakable brutality. there was a broad based sense of revulsion today in this meeting of horror and the deep commitment to do more to try and bring the end of the violence in the region and of the world. >> reporter: unlike the last round of talks in october, this time several concrete steps were agreed to and a time line was established. first, the establishment of formal negotiations between

representatives of the syrian opposition and the syrian regime. the hope is that those discussions to be held under the auspices of the united special envoy for syria would begin no later than january 1. >> translation: the syrian government has already informed of the composition of the delegation. he has a task to find the composition of the syrian opposition delegation which should be representative and reflect the whole spectrum of political forces. >> reporter: the next goal, the establishment within six months from now of a non-secretary tearian unit government that would, among its other duties over sea the creation of a new constitution. finally, within 18 months elections that would take place under u.n. supervision and with an emphasis on transparency and accountablity. a new found sense of urgency surrounded the talks yesterday with a poll over the

proceedings, it was clear that the members felt there was no time to waste. >> europeans, arabs, east and west, international community is all affected by terrorism and those that try to divide us and spread panic, and the best response to this is actually coming together, coming together over coming our differences and trying together to lead the way towards piece in syria. >> reporter: one worry expressed by everyone involved was how a continuation of the war in syria would continue to create even more of a haven for i.s.i.l. and other extremist groups. >> reporter: while substantial agreements were reached, many outstanding questions still lyn angered such as which groups involved in syria's civil war other than i.s.i.l. would be considered terrorists going forward. the other outstanding issue, a big as question now as in other

they told us about this - that they've been there and they mentioned all the details. so this is the evidence. >> reporter: given the ferocity of the air strikes and the peshmerga advance, it is likely that vital evidence of i.s.i.l.'s killings in this town will have been lost, but for the people a relief some evidence is at least being discovered the president of myanmar has made his first speech since last sunday's general election. he has reiterated his government's commitment to a peephole transition of power. the opposition n.l.d. party led by aung san suu kyi swept to victory in the historic pole. the election was a test meant to his government's reforms he said. in argentina political history has been made for the first time.
