the united nations calls for peace talks in yemen as a 5-day ceasefire comes in effect. you're watching al jazeera, also coming up on the programme. more than 40 are killed by gunmen in a bus attack in the pakistani city of karachi north korea's defence minister is executed apparently for showing disrespect to leader kim jong un. plus... >> i'm on the navaho nation in

arizona, where obesity and diabetes is rampant and the governor things a new tax on junk food may be the solution. a 5-day truce in yemen seems to be holding for now, despite reports of houthi shellings in some areas. the ceasefire was proposed by saudi arabia to allow in humanitarian aid. it begin a day after air strikes and shelling by the houthis. in the southern city of tiaz 10 were killed in houthi attacks. in iran, they said they will not allow saudi arabia forces to inspect a cargo ship bound for yemen. iranian warships are escorting the vessel packed with aid workers and journalists.

the u.n. special envoy in yemen has arrived. he says the only way to end the war is through political dialogue. the ship is on the way and in the gulf of add ep the special envoy asked and says the only way to end the war is through political dialogue. >> we welcome the truce and want it to happen, we have two main points we would like to address with regard to the humanitarian crisis. first, the ceasefire must be unconditional. second, we must be able to give aid from south to the northers east to the west. we came knowing there was no solution but a political one yemen has no choice but have all sides sit at the table. hashem ahelbarra is there, he says the ceasefire is holding, but it is fragile. >> the from the international community faces is to convince

all the parties to observe the ceasefire, this is why there are sporadic clashes in different parts of the country. the general sentiment is in the coming hours we might see the ceasefire implemented across the country. >> the point of the ceasefire is to allow humanitarian aid in. we have reports that iran will not allow a cargo ship to be inspected. we believe there are humanitarian aid workers, journalists. what sort of impact if any could it have on the ceasefire? >> it will further the mounting tensions. the saudi-led coalition maintains that it has a no-time blockade, and at the same time controls the air space, under the united nations 2016 resolution, and a mandate by the government. they will not allow any ship into yemen unless it is inspected. once it is inspected. it will be directed to the

united nations coordination centre that will look after the distribution of the aid. the concern - saudi concern is the following. the concern that iran has been in the past providing the houthis with significant financial and military assistance. they would like to ensure no cargo has weapons for the houthis. there's also a push to move fighters out of an up to. opposition groups took over the town, and rebels tried to take over a fortified hospital where troops are holed up, but failed. the government launched air strikes targetting rebel forces around the hospital. this is where government shelling in aleppo province. it killed 50 people in the town

and left are dozens injured. >> fights has intensified. hezbollah fighters are pushing onto three frouned. they are all north-western, the capital damascus inside syrian territory. hezbollah is talking about making gapes making coins on hill fops and inflicting casualties among the opposition. the coalition of groups including the al nusra front say they have repelled attacks and inflicted casualties on hezbollah. they are following a hit and run. they know the terrain, it's rugged and hard for hezbollah. further north in idlib, and others, we have rebels managing

to infiltrate a hospital. that hospital has between 200 and up to 250 soldiers hold up there. that's when the town fell. the entire town and the wider province is considered a gateway to the city. that's the strong hold for the president >> reporter: a group linked to the taliban claimed responsibility for an attack on a bus in karachi. gunmen and motorcycles killed many people. it belonged to a branch of shia islam. >> reporter: this was bus was packed with commuters when gunmen stopped it and opened fire. dozens were killed. mostly a minority. investigators believe it was a planned attack.

>> 9mm handguns, smzs and other weapons. they fired at them inside the bus, and not from outside the bus. >> a splinter group of the pakistani taliban, jundila. it is known for targetting shia communities. it was said to be behind several attacks, inclugd the pakistan indian border suicide, and targetting an intelligence agency compound in 2013, it pledged allegiance with i.s.i.l. leaflets were left on the site of the attack linking it to i.s.i.l. witnesses say the attackers were on motorbikes, some were wearing uniforms. this bus is run by the israeli community to take and bring back people from work. it's not the first time they've been under attack, but a rare attack on these people. for several armed groups operating in the area, it's likely to take longer to bring an end to the violence.

let me tell you what is going on in burundi, there are reports that the president has been removed from his position. by the military. we have reports disputed by his office. as soon as we get clarity on that we'll let you know. there has been a lot of protests in the streets after he said he would run for a third term which is said to be unconstitutional. >> thousands of migrants from myanmar and bangladesh are held in malaysian detention centers after arriving on crowded boats. the united nations urged malaysia's government to find a more permanent solution. we have a report from the north-western island of lan cowy. >> reporter: frightened and exhausted hundreds of bangladeshy migrants and rohingya muslims fled, many facing violence, only to be trapped at sea by ruthless traffickers, who beat them and

provided little food or water. >> people are on the boat three months, two months, and they were collecting more and more people. >> authorities are moving them to detention centers. the government needs to find a permanent solution. >> the government should think of a way to stop human trafficking. and take more series action -- serious action. if they don't, trafficking will go on and get out of control. al jazeera has been told crowded boats will not be a allowed to enter malaysian orders unless they are sinking. >> we expect a few more to come in the united nations is warning that a humanitarian crisis is unfolding, with possibly thousands of desperate people drifting in the ocean.

human rights groups are urging the government not to turn back migrants at sea, saying it's equivalent to signing their death warrant the european union is accepting a new lot of proposals. some of them were described in brussels. >> increasing our engagement on conflict prevention crisis management starting were the areas of conflict from where the majority are fleeing in these times. middle east, syria and libya. increasing our work with the african union, african and arab countries, countries of origin. i mentioned libya. this is i guess, going to be an element for questions. but as you might have noticed we

have increased more our level of engagement with all different libyan parties in the state, to make sure that we can work with each of them to fight the trafficking and the smuggling of human being on the territories. >> there are complications within the e.u. to process migrants as stephanie dekker reports. >> they fear for their families at moment. they don't want to be identified. they know the implications of being fingerprinted. >> most of us do not have intentions to stay here like i want to go to u.k. some other friends want to go to germany, holland norway. if they stay here, they are not going to be able to go outside. >> if they take the fingerprints. >> yes. that's why they don't want to do it.

>> there's cases where refugees arrived in a country of choice and have been sent back to italy because they've been fingerprinted here. eritreans and others have refused to give their prints, all to do with the european migration law, which is randomly enforced. it's called double regulation, and deals with who responsible. who is responsible for processing the migrant's application. under the regulation, it should be the migrant's first port of landing. italy is struggling to process claims of tens of thousands. there has been more than 160 thousand claims since 2011, and more than 64,000 last year. it means that those that arrive and want to stay, can wait around a year for their application to be processed. >> it can double in regulation, it is completely outdated. the three e.u. border countries can implement it due to enormous amounts arriving.

many refuse to take fingerprints, sometimes authorities don't ask for it. it affect public security as many travel on unregistered. >> the european union is discussing how to deal with the influx and considering human interaction. it's a risk people will take in search of a better life will not be solved by military force. >> we know if we take the risk we could die or live. basically, our life is in our hand. so if you ask why did you take that risk, it is obviously because we were not safe in eritrea migrants say they'll continue to make the dangerous journeys. any decision europe makes will need to take that into consideration. stay with us there's a lot more coming up after the

say they think should happen or will in recent days as the protest and violence escalates. the army scene has been neutral. they are out from the treat during the protest, and while police will shoot at the protests, the army will step in between and urge police to use less force. it's neutral to some protesters and some are on their side and are there to protect them pro testing without being shot at or killed. for many it's not the case. the presidential provider said that this is not serious. we are yet to find out if or if not the military has subpoena

control. >> the protesters on the street because they were angry at him running for a third term. thank you for that. >> a train accident in philadelphia killed at least five and injured nor han 50 others. the passenger plane derailed on its journey from washington d.c. to new york city. gabriel elizonda joins us live from philadelphia. what is the status as far as victims and getting people out of the train is concerned? >> well there's over 2 huned passengers on the train. the major city walked away unscathed. more than 50 were sent to the hospital. 50 injured. at least six or sex seriously. the death toll is at six. the crash scene is behind me about a black behind me.

we are being kept away from it. fire officials and crash investigators are combing through the rubble to get a sense of what caused the crash, as we arrived in the early hours of the morning in philadelphia, trying to get to the scene, there were a lot of police and fire officials blocking the streets, directing people and showed the urge say that everyone was trying to get people rescued and get them to safety and the hospitals, there'll be a long investigation trying to figure out what caused the train to derail. >> police have been questioning a lack of vestment in the infrastructure in the u.s. this could be a problem. >> absolutely, that's a question that comes up often in the yate about infrastructure and roads and bridges and the train

system. this train was going from washington d.c. to new york it's a heavily travelled route. there are dozens of trains that do that route. over 11 million on that route. there's talk by amtrak, the train company and law-makers pushing for funding for the rail system in the united states and for this line. it's heavily travelled. safety security it comes up. this is an accident that will raise those questions. >> gabriel elizonda with that update south korea's intel fence services say north korea's defence minister has been executed, and is believed to be the latest in a series of senior officials executed. harry fawcett reports from

seoul. >> reporter: is this the moment he sealed his fate. he is said to show that he dozed off during april. sol picture with the supreme leader was supposed to have been killed for trees jp, failing to carry out his actions. south koreans are calling it it as consolidation, rather than crisis. our government sees executions as a way to create a fearful atmosphere to promote consolidation of the one and only regime. >> reporter: with the suddenness of the fall, he was envoy to a security meeting in moscow, led some to question stability of the leadership in pyongyang. 15 other officials have been executed since the start of the year. >> there has to be better systematic ways to ensure the order of the system, rather than this quick removal. the quick removal, the way it

was carried out indicates the weakness of the system, not the strength unlike the case, kim jong un's uncle, publicly humiliated before his execution, there has been no official announcement. >> seoul's national intelligence service says the death was public and violent. shot by anti-aircraft machine-guns. it's not the first time he has been accused of killing people. last week, human rights released sattelite image showing what it believes was a killing. anti-aircraft guns with a range of 8,000 metres aimed 30 meter away. north korea worried the south. shooting a missile undetectably from the submarine. it is monitoring effects from what it calls a rein of terror.

french leader is a painful reminder of a harsh colonial clash. there was a revolt in 1804. it demanded conscious to slave owners that many believed crippled it since. if haiti is in misery today, that's because of france, why we are organising france to comment us. >> if francis hollande wants to visit haiti, he has to come with restitution. we fought them for independence, and they forced us to pay them to recognise it. >> like generations of french leaders, they spoke of a moral debt. they talked about investment in the future. >> reporter: france today wants to help in the development of haiti, we believe in haiti, because you have considerable opportunity.

mr president, you mentioned you have a young generation, because you have an impatient generation demanding and wanting to work for the future. >> reporter: civil rights lawyer who worked for the haitian president says france's obligation is clear. >> france does owe something to haiti given the circumstances that the haitian people see themselves in. they should have clean water, they should have infrastructure. these are the kinds of things that the french can help right away haiti was still paying off its so-called independence debt to france in 1947. francis hollande's visit opened up old wounds. repatriations are unlikely leaving them to ask whether they can rebuild with a former power without compensation. in the u.s. in the native american community, it is in the midst of a public health crisis obesity rates are rising because

a lot to learn from what navaho did. >> not everywhere thinks that shotgun food tax is a good idea. >> they know that we can't afford, us know, all this. >> reporter: the owner of the store who declined to speak on camera said sales have gone down since the tax went in effect in april. a longer term solution says navaho president is to return to traditional foods, and eating habits. >> we have subsisted on desert economy. and we have gotten away interest that. the desert economy. sustained good health for the people. they lived off the land - roots berries, and things that they grew themselves. we need to get back into living off the desert. an ancient land and its people struggling to get back on the path to a healthy life.
