tuesday's back-to-back bombings in brussels. the state broadcaster has named two suspected suicide bombers as brothe brothers. they have police records. the third suspect named remains on the run. in the immediate aftermath of the attack on tuesday morning, an haze of confusion and chaos. travellers and airport staff ran. >> translation: people were dying one after the other. we were trying to keep them alive, but the worst was people with throat injuries >> i'm so scared. i feel like it's the end of the world. i heard an explosion and the ceilings were going down and i

just go under the sink and then a second explosion went and then everything is black. >> reporter: around 40 minutes later another rush hour blast ripped through a subway carriage in central brussels. passengers escaped as quickly as they could. the metro station is close into the european parliament complex, the heart of the european union. emergency crews treated victims on the pavement as the army kept guard. triggered by concerns of further attacks, the public transport system was shut down. parts of which remain closed. the belgium government has raised its terror alert to the highest level. >> it's difficult to take a train, but you must have the courage to take it because if you don't take it, the normal life, you give the terrorists a

chance to win, to win the game and we can't do that. >> reporter: three days after national mourning have begun. i.s.i.l. has admitted carrying out the attacks. security service commanders had warned of a possible follow-up strike to the paris killings four months ago. the bombings in brussels now confirm those fears live now to al jazeera's dominic kane who is outside brussels international airport. the suspect have been identified, two brothers who were known to police and had a record. tell us the latest about this investigation. >> reporter: certainly the police authorities have been actively trying to get hold of this third suspect who is seen on the cctv footage wearing the

hat and who fled the airport. he had not used the suitcase that was on the trolley. we understand that the three had [technical difficulties - multiple speakers]

there is some interference there, but tell us about the mood in brussels today. the transport system is slowly starting to reopen, but i imagine this is having a huge impact on people's lives there. >> reporter: yes. very much so. the one thing to say is the sense that it appears to come from public sentiment is the shock in the first instance and then the realisation that many people seem to be coming , that this is something that happens more often in their society. for example, the magazine here, which says brussels 22 march, the horror.

there's an image of some of - a victim of the explosion a burns victim with burns wrapped around the person. you may recall the attacks in london in 2005 of a particular individual who was a burned image and that image is recommend his tent to that. that is picked up by the dutch language newspaper which makes a connection with what happened yesterday with what happened in new york in 9/11 with the madrid bombings, lon, done-- london and paris. people are making can connections with what is happening in brussels now and the other major incidents that have happened in europe and the western world. that's clearly something that has come from the media. then insofar as what's happening in brussels today, as we've said, the transport infrastructure has been locked down. some major rail stations have

reopened, but with access being monitored by the security agencies and the roads are still very grid locked. coming here this morning it was very difficult for us to get as close as we are. this is as close as the authorities will allow us to get to the airport which, of course, remains closed to automatic flights thank you very much for that update. al jazeera's dominic kane reporting there live from brussels. as belgium comes to terms with the events of the past 24 hours, many people are now asking why the bombers to chose to target brussels. jacky rowland reports. >> reporter: it's the end of a traumatic day. people take a moment to honor those who died and to think of those who even now are fighting for their lives. there are so many questions. how could this happen and why did the attackers choose brussels? >> being a city that is close to me that i love, i'm not from here, but i've been living here

for quite a while, it came as a shock and it was hard and honestly today has been emotionally exhausting. >> the station, it's really a place where you go every day to go to work. it's really a thing that you don't even think that something could happen there. >> reporter: to begin answering those questions you have to go back to last november. police quickly established a brussels connection to the paris attacks and raided homes in the melombeek district. they were looking for cells that coordinated the attacks in paris. that search culminated dramatically in the capture last week of the primary suspect salah abdeslam. it had taken police more than four months to find him. he had slipped through their fingers on several previous occasions. >> reporter: it was in the building behind me that belgium police finally arrested salah

abdeslam on friday night. security officials warned at the time that in these networks, when one cell is closed down, others are often activated and that seems to be exactly what has happened. >> reporter: in percentage terms belgium has seen more of its citizens travelling to syria than any other country in europe. molembeek and other deprived areas have proved fertile ground fo people without jobs, prospects or hope, the i.s.i.l. message is simple and seductive >> i.s.i.l. was interested here was in groups of small criminals, drugs dealers and so on. they are approached by hate preachers, as we call them, who turn tear mind and this can happen in a very short time >> reporter: the timing of these attacks just days after the arrest of salah abdeslam cannot

be a coincidence. the bombings appear to be more than an act of revenge. after all brussels host the e.u. and nato headquarters. this seems to be an attack on the heart of europe and all it is meant to stand for. jacky rowland artists and cartoonists have been showing solidarity with the people of belgium in their own way. this was published and shows a weeping french flag comforting his belgium friend. far paris was attacked last year. this one has been used in a shared image, and the tears are in the colors of the belgium flan. here is a peace symbol. a location of the two bombs.

finally, this one, the statute, one of brussels's most famous landmark. a statement of contempt towards those who use violence. let's turn our attention to other world news. u.s. republican donald trump and democratic hopeful hillary clinton have won big victories in the primaries in arizona. bernie sanders will be celebrating after he took utah and idaho. they've all been speaking about the attacks in brussels >> this is a contest between fundamentally different views of our country, our values and our future. now, what we saw happen today in brussels, the horrible terrorist attack, reminds us of how high the stakes are. we live in a complex and dangerous world and we need a commander in chief who can

provide leadership that is strong, smart and above all steady in taking on these threats in yemen at least 40 people have been killed in a u.s. air strike on an al-qaeda training camp. the strike close to the west of the coastal city of al mukal larks was led with the saudi coalition. a u.s. described the operation as a blow to al-qaeda and its able to launch attacks. the united nations refugee agency has called out its staff from lesbos and other islands. they say the camps have become detention centers and no longer prepare to work there. >> reporter: for refugees arriving here the u.n. staff have been a welcome sight. whether they meet the beats or travelling on foot, they have been guiding people to the camps

which have become known as hot spots. not any more. >> under the new provisions these so-called hot spots have now become detention facilities, so accordingly and in line with u.n.h.c.r.'s policy on opposing mandatory detention, we have suspended some of our activities at all the closed centers on the island >> reporter: they say the deal between the e.u. and turkey, which is meant to stop the refugee flee through europe, is being prematurely implemented and without safeguards. new arrivals are to be able to apply for asylum but stayed in camps. they say people are being held against their will on several greek islands. no longer will it transport people to the camps. it will continue some services, kwlug counselling. >> they have a mandate to protect refugees. it doesn't have a mandate to

detain them. it's not going to be involved in processing and facilitating mass deportations. it is there to protect them and to see that they get proper information and they will continue to do those things. >> reporter: greece has begun sending thousands of refugees back to turkey, but more still come. only now when they land the blue tab staff won't be there to greet them there's plenty more ahead on al jazeera. >> reporter: i'm in hong kong at the largest contemporary art fair in asia, but what impact does the economic downturn have on the market in this region. region.

welcome back. you're watching al jazeera. a recap of our main stories this hour. two brothers have been named by belgium tv as the suicide bombers. a massive man hurt to catch the third man seen by security cameras. 34 people were killed in the coordinated attacks at the airport and a metro station in brussels. in yemen at least 40 people have been killed in a u.s. air strike on an al-qaeda training camp. the strike was coordinated with the saudi-led coalition which has been conducting a campaign against houthi rebels in yemen. u.s. republican front runner donald trump and democratic hopeful hillary clinton have won big victories in primary elections in arizona. hillary clinton's rival bernie

sanders took ewe tan and idaho. the u.n. special envoy for syria says the attacks in brussels highlights the urgency in resolving lgt syrian conflict. staffan de mistura has just met with government officials to continue the talks and the u.s. secretary of state john kerry will later meet with the rush president vladimir putin in moscow. to james bays who is in geneva for this. lots of meetings happening today. tell us about how things are progressing there. >> reporter: i think the worry is that these talks are getting bogged down and thursday is supposed to be the last day of this round of talks. the opposition are talking about the key issue of political transition and presenting their plans for an interim government, but when the government have their meetings with staffan de mistura, and they're having one now, they're mainly talking about procedure of these talks and want to talk about the counter terrorism issue. it suggests that, perhaps, these talks need a jolt and the

intervention from the u.s. secretary of state and the russian foreign minister and that was a point i put to the u.n. mediator, staffan de mistura. >> we always need some help from mr kerry and mr lavrov because they've been proving in the past, and i hope in the future they prove it, that when they have a common understanding it helps enormously the process. >> reporter: it's clear from what we're hearing from officials and diplomats that the opposition certainly do have plans unlike the government that they're putting forward on the future of syria. staffan de mistura put to both sides a questionnaire, 29 questions, about political transition in syria. my understanding is so far the government have not given in their questionnaire. the opposition, though, have, but i've managed to read that document. what's clear to he is that they

don't want to fall into the mistakes that were made when sudam hussein was forced from power by the u.s. they want to keep a lot of syrian government in place, removing just key individuals and keeping much of the existing government in damascus in place. the only exception is the security sector and it's clear there that they want their new governing body to have a chairman who will take the role instead of president bashar al-assad as commander in chief and they say that they want to make sure that anyone responsible for any sort of abuses is not allowed to have power in the security and intelligence sectors in a new syria. quite sophisticated plans coming from the opposition on the way forward in syria, the government it seems for now is stalling thank you. the u.s. based rating have

issued a low score for lebanon. it is tied between the government and other middle eastern countries angry at people under huz. >> reporter: banking is big business in beirut. for decades the sector has positioned itself as an hub for middle east finance. the international monetary fund recently praised the issue for overture ability and flexibility. that seems to be changing. the u.s. based standard of the credit rating agency has revised its long and short-term outlook for the lebanese banking industry from stable to negative >> we have aborigine absence of a president and where-- an absence of a president. where the parliament is not functioning, it is also due to security risks that are the consequence of the war in syria. >> reporter: regional analysts say the down grade is tied to a

series of measures against the lebanese government by saudi arabia and gulf allies. last month the saudi government cut billions of dollars in aid to lebanese security forces. gulf countries also warn their citizens to leave the country and the g.c.c. and arab league declared hezbollah a terrorist organization. it is the political group which is aligned with iran. the sharp downturn in ties has rattled the financial sector. so now if you're the 300,000 lebanese working in gulf countries could be sent home. >> they do represent between 7 and 8 billion dollars a year. we don't feel that the saudi position is hostile to the lebanese people, but it is also one of the consequence that lebanon had to absorb because of the syrian war.

>> reporter: as part of efforts to diffuse tensions, the lebanese prime minister has said lebanon has wronged arab gulf countries and has promised to make amends. >> reporter: the g.c.c. is sfleeg frustrated with the rising influence of hezbollah. for years the gulf states have provided lebanon with military, diplomatic and economic support and although there are concerns that ties could worsen even further, many here are hoping that it's history of durability and flexibility will help steer it through whatever happens next the former mayor of toronto rob ford has died at the age of 46. he had been battling an aggressive form of cancer. he gained publicity after being in a video consuming crack

each one is trying to create edgy pieces that stand out from the crowd. >> translation: my work is the creative variety of pieces and possibilities using sound. >> reporter: but it is not the only show in it town this week. there is an array of art fairs and exhibitions around hong kong. this artist was born if beijing but moved to spain. he has returned to the region to grow the modern art seen >> translation: i wanted the collectors market to grow so these could be produced to more people >> reporter: this is the fourth year in hong kong. last year around 60,000 people visited and organisers are hoping with more events planned, this the translate to greater interest from local and regional collectors. in particular, the big buyers from mainland china. the contemporary art market is still young in china and this

art fair ask about sales as much as educating the local audience. >> the art collecting and buying in this part of the region is still traditional conservative aclassical chinese art, but the thing about asia, like so many other things, is that people learn very quickly >> reporter: the economic downturn appears to have put a dampener on the sales. even so, the organisers are optimistic about business this week. >> we do have a lot of chinese coming as well. we've got australians, japanese, koreans, collectors from south-east asia. it will be a great show >> reporter: one they hope will bring a fresh perspective on asian contemporary art afghanistan's cricketers are all but out of this year's
