>> world leaders discuss how to combat the threat of isil as the paris attacks dominate the agenda at the g-20 summit in turkey. >> hello, from doha, coming up in the next 60 minutes: >> french prosecutors say friday's attacks were a complex cross border operation. >> parisiennes gather to pay

tribute to those attacked. >> saving gorillas and chimpanzees. >> let's start in turkey where the leaders of g-20 leaders annual summit is supposed to be about boosting boosting cooperation in trade and economic growth but all about security. paris attacks have flipped the focus, solving the crisis in syria now dominating discussions. >> we will redouble our efforts working with other members of the coalition to bring about a peaceful transition in syria, and to eliminate daish as a force that can create so much pain and suffering for people in paris and ankara and other parts of the globe.

>> bernard smith is live in italyia. tell us what the leaders are considering when it comes to border control. >> they've received a copy of a draft statement expected to be formalized later tonight. that draft statement says teach agreed to step up border controls and aviation security. we don't know yet exactly what that means when we talk about stepping up border patrols. perhaps two of the most significant borders are here in turkey, turkey's border with syria and turkey's border with greece, bulgaria and the rest of the european union. the border with syria is pretty well patrolled these days, much tighter than it used to be, it cannot be completely sealed and of course syrians seeking help and refuge are allowed in on a humanitarian base by the turks. however, it is quite easy,

although remains a dangerous journey to go across the sea from turkey's aegean coast to those greek islands, so will turkey be stepping up patrols on those borders? will it be harder now for refugees to leave turkey? then in turkey, the sheen again zone is a border where one can drive across. there is a suggestion that the rules in the sheen again zone may change. >> tell us how much of a shadow is cast by the paris attacks on the gearing there. >> this is essentially supposed

to be about the economies and trade, but we have events claimed by isil, so it was already on the again da here, but we seem to be getting suggestions from the world leaders already spoke that there needs to be more of a joint effort to fight isil. vladimir putin said we need an effort to fight terror, he said at the meeting of the bricks meeting, so suggestion that the end of all of this may be more of a joint commitment to fight isil, sammy. >> bernard smith from italyia. >> 129 people were killed and 352 wounded when a group of

gunman and suicide bombers targeted six locations in paris. police found an abandoned car filled with ak47 rifles, the type used in the attacks. one of the bombers of the concert hall has been identified as a 29-year-old paris native. some of his relatives have been taken into custody. police don't know who the other attackers were, passports have been found at the scene. police are trying to verify who they belong to. we have more from paris. >> french military on patrol in the streets of paris on this a second day of mourning for those killed in the country's worst attack since the second world war. more than 80 people died and the

area sealed off. amateur video captured the moment the killers opened fire on concert goers. in another video, police prepare to storm the building. [ gunfire ] >> they are pushed back in a hail of bullets as well as the bloodshed. one of the killers left a vital threw, a received fink their allowed investigators to identify him at 29-year-old french national. six members of his family, including his father and brother have been arrested. >> he caught the attention of the police due to a violation of public power. from 2004-2010, he was pronounced guilty eight times but was never imprisoned. in 2010, he was blacklisted by the police due to extreme behavior but never classified as part of an illegal extremist group. >> police have also found a syrian passport at the site of the france bombing, used by

someone claiming refuge on a the greek island in october. several men have been arrested in belgium. investigators say they are connected to a car found near the concert hall. >> multiple arrests and search warrants have been executed. these are still on going as we speak. >> authorities in germany say a man arrested earlier this month in a car loaded with explosives might be linked to the paris attacks. mounting tricks to those who lost their lives, many injured remain in a critical condition. after the attacks on charlie hebdo, the authorities are warning against large rallies, still worried about security. >> ther authorities are looking beyond front for clues. this colorful controls mow poll

tan city is struggling to understand the mass murder that happened here. the french good afternoon is calling for unity. al jazeera, paris. >> let's go live now to jacky rowland in paris. >> this underlies the international dimension of this investigation, the latest arrests coming from belgium. in fact, five people, in fact seven now, the latest report we've heard that just seven people have been arrested, most of them from the a poor district of brussels. what we're hearing from belgium, coming from the prosecutor's office is that two of the attackers, according to the belgian authorities, two of the attackers who died in the paris attacks on friday night were from brussels. it's been clear from quite an

early stage that there was a belgian link or a belgian connection at the attacks, because one of the cars used by the attackers were traced to belgium, so this is really an example of how there is a lot of cross border cooperation in trying to get more confirmation on who was behind the attacks on friday night and also what kind of networks or accomplices could still be out there. >> there's a lot of excitement about passport which have been found. let's stick with the facts and ask what do we know about passports and what do they factually tell us at this point. >> we know from the french prosecutor who spoke that at the scene of the nightclub attack that a syrian passport was found belonging apparently to a person born in 1990. there were also conflicting

reports about whether a passport, syrian passport was also found at the stadium, where, of course, there was some explosions early on friday evening. now, in terms of those passports, the passport apparently belonging to someone born in 1990, we know that greek authorities who are process be refugees arriving in greece in october heads that someone carrying that passport had passed through the island of laros october 3 and beyond that, we don't know if the pepper carrying the passport was the same person as the same on the passport, no way to know whether the passports are real or fake and no way to know in such a confusion when you've got 129 people who have died and all of the bodies have not yet been identified, who cab say which of the dead are victims and which could be perpetrators. one thing we do know is the one person positively identified as

an attacker was a french national. of course, those reports from the police in belgium, that they believe two other attackers who died came from brussels. at the moment in terms of concrete evidence, the attackers that we know of were those living and were actually holding citizenship here in france, and as well in brussels. >> thanks for that. >> crowds of people are gathering in paris to pay tribute to the victims of those attacks. jonah hull has more on the first of the three days of official mourning. >> two days after the attacks, shock lingers, and grief at some of the scenes of friday's carnage, people gathered to pay their respects. the restaurants opposite one

another. >> we were almost expecting it. we knew it wasn't going to be the end after january, but when it happens, you're always surprised. you think it's not possible, not in paris, not like this, so brutally. >> the emotional scenes, of course, whispered conversations, the only sound really the hum of vehicle engines. this young woman is worried about an injured friend. >> i have a friend who was shot three times in her legs, and injuries to her face. she's in stable condition, but psychologically, it's going to be very, very difficult for her, for her friends and even her family. >> i have lots of respect for the victims and their families because i know the area very well. i come here all the time.

we could have been hit, too, and frankly, it's very upsetting. >> away from these locations, so solemn, so quiet, the police investigation is widening, taking in locations from belgium to montenegro to the isles of greece. >> those killed in unseasonly mild weather as they ate and drank on a friday night out. >> still ahead, mass graves containing the bodies of members of the yazidi minority discovered in the iraqi town of sinjar.

>> why front, why france, given all the resources and attention, why that is being paid to france when there are so many countries which are participating in the so-called war against isil? >> you're talking about targets of opportunities. think of what has happened in the last few days. the russian jet in which 224 russians were killed, allegedly by isis, the attacks in the heart of beirut, dozens killed and injured. again, the attacks, we don't talk about what happened in baghdad and now the attacks in

paris. paris is very special. you have obviously the militants, jihadi elements, various al-qaeda variety, have assets in paris. obviously the only suspect identified is french-born and the two killers during the january attacks are french. what does it tell you? it tells you that the various jihadists have major people in the country, that you have french people who basically buy into this ideologies. it's easy to have weapons and ammunition. it's an open city, but at the same time, we should not just blame the french and say look, the french could have done more. who knows what's going to happen. here i am in the u.k. and i can tell you that the british security authorities are terrified. they say it's a matter of time. this particular virus is spreading. they have the capacity, the

organizational skills and unfortunately, and sadly. you have some delookedded young men who buy into this ideology and kill civilians randomly and brutally in the way that we witnessed on friday evening. >> do you think one of the outcomes of this attack has been the world waking up to the importance of trying to find a political solution to syria, to sort of fill the vacuum that allowed groups like this to flourish? >> i think this is really the most important question about element in the debate. the question is how do you basically put out the fires in the heart of the middle east, in syria, and the iraq, libya and yemen? how do you basically end the civil wars in syria and iraq? how do you ept the sectarian strife? this is giving al-qaeda and isil

ideological ammunition. without ending the civil wars in syria and iraq, this particular virus, this disease is going to spread near and far as we have witnessed. look, yes, tragic in kid with us, painful what happened in france, almost 300,000 syrians have been killed. 300,000. probably a million injured. think of the tens of shouse thousands of iraqis killed and 11 million syrians between refugees and displaced people. it is one of the greatest tragedies since world war ii, indeed. >> the paris attacks have provoked reactions from democratic candidate dates who are hoping to replace the u.s. president. the party's final three hopefuls met to debate in iowa. >> they came bearing signs of support for those still reeling from the paris attacks, and now wanting answers from the

democratic candidates about how they prevent similar attacks in the united states. >> my heart goes out to everyone in paris. i feel a lot of -- their sense of loss. >> it's concerning to me about what's going to happen in the future. i do want our presidential candidates to talk about what we are going to do to protect our country. >> the moderator asked the same question. vermont senator bernie sanders replying votes fought invasion of iran in 2003 was contributing. >> i would argue that the disastrous invasion of iraq, something that i strongly opposed has unraveled the region completely. >> i have said the invasion of iraq was a mistake, but i think if we're ever going to really tackle the problems posed by jihadi extreme terrorism, we need to understand it. >> it was an exchange that dominated the debate and

immediately following had clinton's team struggling to spin. >> she has said that invading iraq was a mistake. >> but it wasn't just to acknowledge a mistake, does that go far enough? we can certainly all acknowledge contributed to the instability in the region. >> ultimately, but that's the kind of thing that voters decide. >> in february, iowans will get their chance when the state holds the first presidential nominating contest. >> there were domestic issues discussed in the second democratic debate, but given it comes just one day after the paris attack, the candidates' positions on battling isil are whether are making headlines. al jazeera, dough money, iowa. >> egyptian police shot dead 15 asylum seekers in the sinai peninsula. authorities say they ignored warning shots as they climbed

the fence to try to get into israel. eight others were injured. >> the bodies of dozens of yazidis have been found in a mass grave in northern iraq. the discovery was made after kurdish fighters recaptured sinjar from isil fighters. the grave could be one of many. >> after the peshmerga advance swiftly into sinjar, evidence of isil's brutality comes to light. a peshmerga soldier places items that investigators say were found only site. they include bones, hair, and personal items. he said members of his family and relatives of buried here. he's angry at what happened. >> we understand this is war. we know people will die, but this is more. we will never forget what they did here. we will have our revenge. >> according to the u.n., isil killed 3,000 yazidi men and women when it took control of

this region in june be 2014. the yazidi community practiced an ancient religion and isil considered them her particular and forced them to convert to islam or be killed. they enslaved young women. that sparked international condemnation and caused the u.s. to start airstrikes against isil. >> it is likely that more mass graves will be found. >> the head of the local intelligence department said it's further evidence of isil violence. >> we keep finding evidence of their actions. this needs to be documented and recorded. >> it's up to this man to record that evidence. originally from sinjar, he's worked with the international criminal courts for 13 years and now advices the kurdish regional government on more crimes and genocide. he said this attack took place august 15 and this grave

contained 76 bodies, including young women and that it might qualify as genocide. >> they told us they managed to escape from isis, and they came to our center for interrogation and gathering evidence. i am leading that. they told us about they'd been there and they told us that they had mentioned -- this is evidence. >> given the ferocity of the u.s. led coalition airstrikes and peshmerga advance, it's likely that vital evidence of killings in this found would be lost, but relief for yazidis that some evidence is being recovered. >> at least 16 killed after a landslide hit homes in eastern china. 21 are missing in one village. heavy rain created a for repeat of mud and rocks, burying 30

homes. >> one of the most remote places on earth and the wildlife that thrives there is under threat, according to conservationists who say the forests are being loft at an alarming rate. >> these are the eyes of an endangered blood line. western low land gorillas can relax here in the republic of the congo's wildlife preserve where they're protected from hunters. >> it's down time. >> they've gone from vulnerable to endangered to critically endangered approximate the in the past 60 years, hunting, dwindling habitat and ebola slashed their numbers 80%. there are perhaps 100,000 left. >> disease has been a major influence in certain areas, not all areas. hunting is certainly the most dangerous threat to them in their existence right now, but the spread of logging,

agriculture is also impact be their environment. >> dave morgan of chicago's lincoln park zoo preserved ape happen tats in the congo for sip years. >> the rest of the group is coming up behind here. >> he's helped turn animal hunters into wildlife trackers who now protect their former prey. >> this his the type of job that i feel good about and i can make a living from it. >> this is emily and her first baby, enos. we wear masks to make sure there is no exchange of ideas. researches have spent years making sure they can be accustomed to human presence. despite threatened by logging, inapproachment and being hunt for their meat, they are perfectly comfortable with us being this close. >> they craft their own tools to turn a term might mound into a meal, but even they have no

defense against a dwindling habitat. there are as few as 170,000 than today. chimps she more territorial and less likely to survive a fourth move. >> you have them displaced unone on top of another. once you get two communities going together, you really do see chip manzo carnage. >> researchers spent years getting to know them through daily contact. that can be terrifying. >> a silver back will charge. >> charging you? >> charging the trackers and ourselves. it's risky. people get bitten. in the end, we think it's important to have a couple of groups here habit waited so we can learn more about them and educate people about them. >> in persuading people to preserve the endangered happen

tats may be the last best hope for future generations like enos. al jazeera, republic of the congo. >> if you want to keep up to date with that story and others, head over to aljazeera.com. this is a show about science... >> oh! >> oh my god! >> by scientists. tonight... the digital divide. >> if you had the world's fastest internet, what would you do with it? >> the promise of the digital superhighway. lightning fast hook-ups to the web, but not for most of the u.s. >> the church... most people come here to pray but you come here for what?
