waters the hunt is on to find a suspected i.s.i.l. bomber seen on a security camera at brussels airport. tuesday's bombings there and at a train station killed 31 people and injured 270 others. this is the man who is the focus of that manhunt. his identity is unknown. it is believed he had explosives, but they failed to detonate. there were a total of three bombers at the airport. naj was already a suspect in last november's paris attacks. the third suspect was the belgium born man had been deported from turkey after being caught at the syrian turkish border last june but was released by belgium police due to a lack of his evidence. his brother carried out the bombing at the metro station and

was also a brussels suspect. >> reporter: police are tracking the bomber who got away. he are removed evidence here. just one of a series of raids that have uncovered explosives, detonators and nails. the last known image of the three airport bombers, the man in the million dollars was a contradicted criminal who was identified using his d.n.a. the man on the left also dead has now reportedly been identified as laachraoui. >> he put down a large bag and left before the explosion. his bag contained the largest explosive charge. after the rival of the bomb disposal unit this bag blew up because of the highly unstable

nature of the explosives. nobody was injured. >> reporter: this man is expected to be an expert bomb maker. he was hunted for sheltering salah abdeslam. the paris attacks suspect who was arrested last week after four months on the run. his d.n.a. was reportedly found on explosives linked to both the brussels and paris attacks. it is possible that salah abdeslam was intending to be one of the brussels bombers himself in which case he would have known about the plans and preparations for the attacks. details clearly that he did not reveal during many hours of police interrogation. there's a noticeable increase in security in the center of brussels. not just police, but also army patrolling the streets. at some metro stations police have been checking bags before

letting passengers enter. this is, above all, an exercise in building confidence around feelings of security, but as long as suspects are still on the run the threat continues as we told you earlier, one of the suspect had been arrested in turkey last year. he was picked up in a routine sweep for terror suspects near the syrian border. the turkish president made the announcement. >> translation: one of the brussels attackers was caught in june 2015 and was deported. we informed the authorities, but a note about the deportation on july 14 2015. they released the attacker despite our warnings that this person is a foreign fighters turkey has come under fierce criticism for becoming the main transit point for fighters into syria. the government is doing its part

to shut the route down. >> reporter: securing turkey's 900 kilometer border with syria ask not easy. the government wants to seal it off completely with concrete walls, watch towers and more guards. the construction started about two years ago. some residents here say it's already made a difference. >> translation: they were passing from here, terrorists, man, woman, smugglers. they were all passing from here. >> reporter: turkey says it fears i.s.i.l. fighters are crossing over into its territory with the intent of carrying out attacks. this is the closest we can get to the border with syria. you can see behind me the concrete wall. that was built about a month ago by the turkish authorities. the government says it wants to prevent all smuggling activities and prevent anyone from entering

turkish territory illegally. but powers of accused turkey of turning a blind eye to the flow of foreign fighters in and out of syria. intelligence services estimate more than 30,000 foreigners from 100 countries are fighting in syria and turkey was the intere point for many of them-- entry point for many of them. an estimated 3,000 to 5,000 i.s.i.l. fighters have returned to their homes in europe and could be planning attacks. this 70 kilometer strip of the border is used by foreign fighters to go in and out of syria. an i.s.i.l. stronghold is just a few kilometers away. the government has ridiculed all accusations. he says the concrete walls will run over 800 kilometers through five turkish cities bordering syria, with cameras and radars.

>> translation: men blow themself up in the airport. how did they get there and the bombs? why europe doesn't protect its borders? instead of accusing us, let's work together to solve the problem >> reporter: turkey has increased its military power and personnel along its border with syria, but even if it succeeds in sealing the border, i.s.i.l. and other foreign fighters will find another way to cross as long as there is war in syria pieces of debris found earlier this month on a beach are likely to have come from missing malaysia flight mh370. that's the assessment of the australian government whose experts have been examining the items. they say the metal pieces are consistent with the boeg 777 panels. the plane disand two years ago

been killed in the last year, over hassle civilians. --- half civilians. many are on the brink of famine despite both sides taking and retaking territory from each other, it is difficult to see what they're actually achieving. in fact, human rights watch suggested the main beneficiaries of this war have been the countries who have sold billions of dollars in weaponry since the war began. >> it's one of the most shocking example of double standards sometimes by countries such as the u.s., u.k. and france who rightfully denounce human rights violations in other places, but when the close ally and the major arms importer is involved, have a very different teen. >> reporter: the u.n. special envoy said there was a

commitment to the upcoming talks and he warned this might be the last chance for piece the e.u.'s top diplomat has attempted to breathe new life in the talks in geneva. our diplomatic editor james bays reports from geneva >> reporter: one of the most senior officials in the european union after a meeting with the head of the syrian government delegation in geneva. there were no pictures of the actual meeting between them, but the ambassador was aware of the value of giving interviews straight afterwards. at the same time he headed to the united nations for a meeting with staffan de mistura. she made it clear she had met both sides in geneva and there was no change to e.u. policy. >> reporter: why did you decide to choose this moment to reward the bashar al-assad regime with

such a high-profile meeting? >> i will support to the option-- our support to the opposition has not only been in place for the last five years, butl for the future and this is something we discussed. as i said, what i have done today is consistent, fully consistent, with what we decided together as the european union to actively support the work of the u.n. and in particular that of staffan de mistura in bringing the negotiations forward >> reporter: despite high representative's firm position that this is not a change in e.u. policy, i can testimony you i've spoken to diplomats from a number of different countries who say they are surprised that she held this meeting. one added there is only supposed to be one mediator in this process. earlier ambassador told reporters he would soon be returning to damascus after almost two weeks in geneva, the opposition say he has not even

started to discuss the key issue of political transition. they're angry that a man who they say has been stalling and delaying has now been granted a high-level meeting time for a short break. when we come back. these argentinians say obama is not welcome. why are people of south sudan seeking safety in spite of a peace deal reached last august. d last august. eventually i started leaving the gangs in the street alone. >> we're pushing the envelope with out science every day, we can save species. >> i'm walking you guys! >> all i wanted to see was her walk. it was amazing. >> these were emotions that i

had been dreaming about for so long. >> getting to the heart of the matter. proud to tell your stories. al jazeera america.

welcome back. a quick recap. turkey says it arrested and deported one of the brussels bomber last year. they say he was apprehended near the syrian border in june. an agreement to ceasefire. this man says this is probably one of the last chances for peace. e.u. foreign policy chief has joined talks to try and end the war in syria. indirect talks between the government and main opposition has all but wrapped up without a deal. the u.n. human rights council is investigating crimes against humanity by north korea. they're looking at how to make them accountable. the isolated state has been involved in what it calls

unspeakable atrocities. north korea has responded to the u.n. saying it totally rejects the resolution. joining us via skype in seoul the director of strategy. what do you think has prompted the u.n. panel now to announce its investigating north korea for human rights abuses? why now do you think? >> this is the latest. over the last couple of years of increased pressure from the international community on north korean human rights issues, they started in 2014 with the commission report that really set the baseline of the international community's understanding of how bad and how serious the issues of north korean human rights is. it has been for accountability through the united nations community council because they will block the avenue to the criminal court. this is another angle that countries can try and take to

pursue accountability for the north korean leaders on human rights issues they talk about unspeakable atrocities. are these reports credible? >> yes. there are a lot of reports, as you said. the biggest report i mentioned, the inquiry report, was based on interviews with around 300 people, most of these were anonymous. the picture of the human rights violations that came out of that was very consistent, very credible. the issue of political prison camps in north korea, for instance, has been crated, not just by factor but by several witness testimonies from people that were former prisoners, as well as former prison guards and corroborated by imagery. the standard of proof on these issues is quite high ask there any connection, do you think, between this u.n. panel report and the american

college student being held by the north koreans? >> i don't think that that is in the calculation, really, of the government and it's not really a linked concern for the international community either. it just happens to be playing alongside at the same time a final thought from you. even if this north korean panel says that north korea and its leader have a case to answer, there's very little the international community can do to bring him to justice, isn't there? >> yes. it is a very difficult issue. even if you have an indictment by the international criminal court, you only have to look at somebody like bashir in sudan, they have been unable to get their things on him. however, nonetheless, it is still important to show that the international community is paying attention to the issues

facing the north korean people in human rights and humanitarian issues and not just the focus on north korea and nuclear weapons and missile development programs thank you very much for talking to al jazeera. u.s. president obama is in argentina hoping to build better diplomatic and economic ties, but u.s. involvement in a dark period of argentina history has cast a shadow over the visit. >> reporter: an historic visit. he came all the way to argentina to mend ties with the country. >> the president is a man in a hurry. i'm impressed because he has moved rapidly on so many of the reforms that he promised to create more sustainable and inclusive economic growth and to reconnect argentina with the global economy and the world community. >> reporter: for more than a

decade argentina and the u.s. were at odds. former president kirchner and her husband moved closer to venezuela and china than the u.s. now things have changed with marri who is promise policies that will bring argentina closer in line to the u.s. >> translation: we take this visit as a sign of friendship when argentina is looking to a new horizontal glon, a new change. our countries have similar values. this marked the beginning of what people say is a brutal dictator ship that would last for seven years. that's why left wing groups

tested. >> translation: it is disrespectful that the president of a country that trained and prepared the dictators is coming to argentina at this time. >> reporter: people see u.s. as a country that supported the dictatorship 40 years ago but also as a nation that continues to violate human rights around the world. that's why these people say that obama is not welcome here. it is said that the u.s. won't bring any benefit to argentina. >> translation: the only thing we see from this is that the rich are going to be richer and the poor poorer. it's what multinational companies do in countries like this one >> reporter: they see things differently and their message is that it will bring more benefit than pain a u.n. court at the hague is expected to hand down a verdict in the trial of the war time leader of the bosnian serbs.

>> reporter: it is not so long ago that a european capital city echoed to the sounds of war. in the countryside people were herded into camps and in one town thousands of men and boys were massacred. they're still digging up bones today. president of the bosnian serbs is accused, the seize of sarajevo, ethnic cleansing. a psychiatrist, poet, ee kolgsist, the role of war time leader didn't always seem a natural fit. after the war he disappeared. nato forces looked for him all over bosnia, but he was in

neighboring serbia, not hiding in secret but designed in public as an mystic healer. his trial lasted five years. defiant he defended himself. >> translation: my conscience is clear. i trust that you will study carefully all the evidence. if that happens, i have no doubt the judgment of acquittal of follow. >> reporter: many serbs still believe they were the victims. this week they gathered to name a building in honor of him. today's leader called the trial a humiliation. he said he was subject to selective justice. what about z; rajevo? the city that was his home for three decades but on which his forces turn their guns.

this man was shot by a sniper 25 years ago. what will a verdict in his trial mean to him? >> i'm looking forward to it. not because it will be any big satisfaction, but a step towards restoring the fate in our society today. >> reporter: for those who lost loved ones, the verdict is important, but if his trial was meant to reconcile bosnia to its past, well, it hasn't worked out that way. the guns have fallen silent but in country is as divided as ever. barnaby phillips in a move likely to raise tensions in the south china sea, fortunately journalists have been taken to an island administered by taiwan. the island is close to where china is building other islands. >> reporter: above the south china sea heading for one of the

specks of land. taiwan's government waited more than 50 years for this moment. to finally allow foreign journalists to see for themselves how taiwan is protecting and enforcing its sovereignty. this is very small. it is half a kilometer long and is dominated by the runway. to but tremendouses its case, tie wran is intending more than 100 million dollars upgrading the run way and also the port. >> this is actually the natural formed island sustainable and good for the living of the people according to the international practice in international law. so the island enjoys the rights of an island. it's not a rock. >> reporter: the tour was to try to prove that life here is

becoming sustainable. the population is now almost 200. coast guard personnel, mostly, as well as a few scientists and medical staff. this doctor will spend eight weeks here. >> lonely sometimes. that's okay. i think two months is a great period, not too long, not too short. >> reporter: taiwan's government says its seventy claim grants its rights over the surrounding waters for around 370 kilometers. that's important because these waters may contain rich reserves of oil and gas. china claims almost all of the south china sea. it also claims taiwan. china's leaders normally sensitive on issues concerning sovereign ultimately have not objected to what taiwan is doing here. in these disputed waters the two chinas appear to be on the same side.

taiwan's isolated status means that it can't be represented at the united nations or other international bodies that have been trying to resolve the south china sea dispute. this trip was about trying to ensure taiwan's voice is also heard. adrian brown the u.n. is setting up a commission to investigate human rights conditions in south sudan. thousands of people have died in a civil war that began in 2013. more than two million people have been displaced. many of those forced out have fled to neighboring countries. sudan has taken the biggest share. our correspondent reports from white nile state. >> reporter: the south sudanese voted to split from sudan in 2011 hoping to end generations of conflict and persecution.

a few years later thousands have returned to sudan desperate to escape the violence in their young country. >> translation: we voted for independence to end the oppression, but we came here to sudan to get safety. here we are not a refugee. we become citizens of sudan. >> reporter: the government policy is to treat south sudanese as citizens with the same rights as sudanese. the war was ignited over a rift between the president and his former vice president. both sides have been accused of massacring and displacing people along tribal lines. l although a peace deal was signed last august, i the violence continues. aid groups estimate that since 2013 more than 130,000 people have fled to sudan's white nile state along the border, hungry, homeless and sick. the number of displaced keeps

increasing. >> translation: in spite of the bad economic situation here, we received people with open hearts because they're other brothers and sisters. we're put in the spotlight on our other partners to assist us in sharing the responsibility for this crisis. >> reporter: sudanese citizens are also streaming over the border. many owned businesses and property in south sudan. the government says they're returning home facing dire circumstances, forced to leave everying behind. this woman and her six family members are crammeded into what was supposed to be a temporary shelter. when they speak of home, they speak of the milk they used to drink from their cows, the fish they used to eat from the river and having sugar on hand. they long to return to south sudan, but they say they can't until there is a genuine lasting peace. >> translation: i didn't expect to stay here for two years, but we're in a war and we should expect this.

here we are safe. >> reporter: here she also found an unexpected gift. she has adopted this boy, one of the many orphaned children in the displacement camps more news on our website. there it is, aljazeera.com aren't even citizens. no doubt this week's attacks in belgium will heat up the rhetoric on immigration in the united states. donald trump spopped almost immediately saying, quote, we have to have strong borders, we have to be very vigilant and careful who we allow into our country. some immigration analysts are already harping on the visa waiver program that lets immigrants into the united states with little scrutiny they say. thousands or millions of
