this is al jazeera. hello there. this is the news hour live from london. coming up more desperate survivors, more deaths at sea as the eu promises action to help those risking their lives to cross the mediterranean dozens reported dead after a missile base is attacked in the capital of yemen south africa's zulu king

blames the tax on foreigners tight security as thousands take part in the boston marathon. two years after a bomb attack at. race. the european union's foreign policy chief says member states must act on the mediterranean migrant crisis as ships responded to distress calls from two more boats carrying about 400 people. they started bringing ashore victims killed in this week's capsize. only a handful of survivors have been found. as many as 950 people were on board. on monday a sailboat carrying

migrants ran aground off the islands of greece. greek coast guard says three people have drowned. at least 90 were rescued. european union foreign and defense ministers discussed a series of measures aimed at discussing migrants being exploited by traffickers. more on that in a moment. first, here's a report from sicily. >>reporter: being battered by waves, clinging to what's left of their boat a woman trying to protect a young child. recent attention has been focused on migrants leaving north africa for italian waters. this stricken vessel came from turkey and hit rocks on this island. this child was saved but three people are already confirmed dead including another youngster. it's not known how many are still missing. on malta, bodies are being

brought ashore. just 24 corpses have been recovered but as many as 900 drowns when they capsized off the coast of libya on saturday night. of the hundreds on board, just 28 were saved. those survivors survivors are on their way to sicily where aid workers are on stand by. this has been a deadly period for migrants trying to cross into europe. the compassion with which those in sicily regard them is vividly illustrated here with this memorial, a monument to those who don't make it. there are 15 graves of adults and two of children. the names of those in the graves will never be known but the words on it are from the poet lauriet from africa.

there will be a european summit meeting on thursday. how many more will have died by then. paul brennan, al jazeera. sicily. let's get more on those eu emergency talks. the crisis was discussed from germany where dominick caine reports. >>reporter: a moment of silence. after a day of meetings here the eu foreign policy chief said it was now imperative to act. >> i think that today we are developing a truly european sense of urgency and solidarity solidarity in fighting human trafficking. finally. >>reporter: the proposed new measures include strengthening its mission in niger, destroying boats used by traffickers which are often unseaworthy or

illegal. to strengthen and give more money to rescue operations and to get member states to share responsibility for the resettlement and relocation of refugees. because the country that has borne the brunt of the migrant wave says it can no longer cope on its own. >> it's a european emergency. it's not the problem to help italy. it's a problem to help europe. you can't have a european emergency and an italian answer. >>reporter: that's the answer to the operation which cost more than $100 million during the 12 months it ran for and which was closed down last year. many migrants crossing want eventually to reach germany. it receives more asylum seekers than any other eu country. and while many say the welfare of migrants is important, they also say solutions need to be found in the countries the migrants are leaving.

>> our very first priority has to be improving sea rescue operations so fewer people die. that is obvious. secondly we know that the migration will not let up as long as conditions in north africa remain unstable. >>reporter: if anything long term is to be achieved, both problems will need to be solved at the summit on thursday. dominick caine, al jazeera. al jazeera has the latest from sicily where the few survivors of sunday's capsize are expected to arrive in the next couple of hours. >>reporter: so another day of drama and tragedy in the seas south of sicily. the italian prime minister saying that there had been distress calls from ships carrying a combined total of some 450 migrants. we've been talking to the president of sicily and he was

saying that the burden of coping with this influx across the mediterranean has to be shared more eh quitablely amongst european countries but if there were easy solutions, they would have been adopted by now. the awkward truth is that european governments are operating in a situation in which they feel constrain bid their own electorates the sheer volume hostility. it's late april, that means temperatures are rising in the mediterranean, the seas are getting calmer and so the expectation is that there will be many more migrants arriving and unfortunately more disasters in the weeks ahead. >> it's also known that some of the christians killed in

ethiopia were headed to italy. isil posted videos of the deaths of about 30 men on social media. it shows some being beheaded while others were shown being shot. >> i have never seen such a bar baric act. how on earth can such a horrible act happen to human kind? how? why? >> our sorrows are great. we're very sad. these people you see are not only neighbors but from ethiopia that came to grieve with us. they all came here after they saw the post about this act against fellow citizens. when a human being is slaughtered like a sheep, it's horrific to the war in yemen now.

the capital has been rocked by one of the largest explosions since the air campaign began. air strikes targeted a missile base being used by houthi fighters. it triggered a huge blast which flattened nearby buildings. at least 46 people are believed to have died. a saudi border guard has killed from mortar mortar and gun fire from yemen. and yemen's foreign minister says the air strikes have so far culled thousands of houthis. the u.n. estimates 750 people have been killed over all. >>reporter: in more than three weeks of bombing, this was one of the largest attacks yet. the target was an scud missile

base. but the massive explosion killed dozens of people destroying nearby buildings and blowing out windows in homes and offices. it also damaged a television station owned by the former president al saleh knocking it off air. picking through the devastation, local residents voiced their anger. >> the munition hit our homes. this is what the cowards use to bombard civilians. >> when we arrived here to help our colleagues and other people there was a big explosion and we found shells over the whole area. >>reporter: it's an area beside the capital center where the presidential palace and many embassies are located. quick to criticize the saudi-led strikes was indonesia whose embassy is nearby. >> i want to strongly condemn the air strikes. several diplomatic staff were

injured and it also damaged the buildings and vehicles belonging to the embassy. >>reporter: for 26 days the saudis have led an alliance against the houthis. they have repeatedly targeted the base along with other military facilities and airports and throughout the country. >> the coalition forces succeeded relatively to destroy the military infrastructure of the deposed president saleh and those of the houthis including weaponry depot which are totally destroyed. [gun fire]. >>reporter: in the port city of aden fighting is fierce. here popular resistance fighters loyal to yemeni president hadi are keeping people out of the district. those caught in the cross fire

are left lying in the streets. houthi says his forces will never surrender. the u.s. navy has sent a war ship and an aircraft carrier to waters off yemen. the u.s.s. theodore roosevelt has been deployed. the u.s. says the ships are there to conduct maritime security operations and not to intercept iranian armed shipments. iran has been accused of supplying the houthis with weapons and backing them >> the lawyer for an american reporter detained in iran says he's facing charges including spying. he's been held by iran since july last year. his lawyer says the charges include conducting propaganda against the establishment and collaborating with hostile governments. the executive editor says the

charges are baseless and ludicrous. >> if reports are true these charges are absurd and should be immediately dismissed and he should be freed immediately and return home to his family. >> for more on the story we're bringing in the "washington post" executive editor. what more do you now know do you think about the case against your reporter? >> well we now know that there are charges against him. we know that one of the charges includes spying. and we now have some sense as to how ludicrous those charges are. he was only a reporter. he's been a reporter for us since 2012. he's been in iran for ten years. he's been an accredited journalist and he's done nothing wrong and the description of the charges against him makes clear just how absurd these charges are. >> i think his only has only

been able to meet with him once. do we know anything about the evidence likely to be produced by the prosecution? >> we have no idea about the evidence. he's been in prison now for nine months. it's the worst prison in iran. he's been in isolation for much of that time. he was denied access to a lawyer for most of that time. he was denied access to lawyers of his choosing. other lawyers were intimidated into not accepting his case. he finally was able to get an approved lawyer and it was only in the last day that he's been able to meet with his lawyer and then only for 90 minutes. so essentially nine months in prison no public disclosure of the charges until now via his lawyer. and a grand total so far of only 90 minutes with his lawyer. >> how much help are you and his family getting from the u.s. government on this case? >> we have the support of the

u.s. government in terms of seeking his release. the u.s. government through the state department and other channels has asked for his release, pressed for his release and we appreciate that support from the white house, the state department and from others. but there's a limit obviously to what they can do. this is within the control of the iranian government and it's not even clear which segments of the iranian government are in charge. but it appears that the revolutionary guard has tremendous influence on the outcome of his case. this is being handled in a revolutionary court and the judge is one of the most notorious judges in iran. >> i guess there has to be hope with improving relations between at the ran and washington might actually help his case. >> of course we always hope but the negotiations between the united states and iran over nuclear matters so far has had

no bearing on his case at all. we believe his conditions in prison have improved somewhat. we appreciate that. but the court and the iranian government appear to be going on their own independent course. it's gone from bad to worse over the last nine months and while we continue to hope for improvement and we continue to hope for his release what has happened so far is very concerning and now he's having charges, surcharges brought against him that could put him in -- keep him in prison for decades. >> thank you so much for coming on the program. thank you. >> thank you. still to come we're going to hear from one man who made that journey across the mediterranean. what his advice is to those planning a similar journey. .

the zulu kings supporters gathered to join him. here's this report. >>reporter: he's one of the most powerful men in south africa respected and adored by millions of zulus across the country. many people say he should have made this speech weeks ago. >> i have come to declare a new war. this war is to protect every foreigner here. every foreigner must be safe.

as your king i call for calm. >>reporter: he said the media should be investigated for misinterpreting another speech he made last month. many say that speech in which he blamed foreigners for the growing crime rate has led to these attacks. he says the violence has brought shame told south africa. >> we should hold hands with the police. those who have committed crimes must be brought to justice. because the law must stop those trying to destroy south africa's image. >>reporter: the king's supporters say the media has lied about him. >> it's good that the king came here because he set the record straight. >>reporter: the government is also being blamed for failing to address the high unemployment and poverty among huge sections of south africa's population. many of whom accuse migrant workers of taking their jobs.

there have been flairups in recent years. a mood of celebration here after the zulu king condemning all forms of violence against fortune foreigners in south africa. there are more than 1,000 people in this camp who came here to earn money for their families across africa. some fled from fighting in congo. she says her hair salon was attack attacked. >> why didn't it stop? it's better to go home. it's better to die home than die here. >>reporter: for her and thousands of people like her, the king's speech offers little

comfort in a place they have come to think of as home. more clashes between antigovernment protesters and riot police on the streets of the capital of guinea weeks since the last violence. demonstrators lobbed stones at police. the government says at least two people were hurt but denied its forces fired shots. the protesters are angry about the election timetable and the fragile security situation in the country. the u.n. has condemned an attack by the group al shabaab that killed at least seven people in northern somolia. four somalis and three foreign nationals were killed. most were employees of unicef. the somali president has called

it a direct attack on the future of the country an egyptian court has sentenced 22 people to death for storming a police station outside of cairo in 2013. one police officer was killed in the attack which happened a day after the military overthrew the government of morsi. they've cracked down on the muslim brother hood group. lebanon has received its first shipments of french made weapons as part of a deal worth $3 billion. it's a saudi-funded initiative to help lebanon battle armed groups in neighboring syria. we have a report on the significance of that delivery from beirut. >>reporter: it was simple but

significant. >> lebanon's victory is a victory to all nations threatened by terrorism. >>reporter: they've waited almost a year and a half for this. the first shipment of a three billion dollars saudi arabia funded arms deal with france meant to bolster the capabilities of their army. at air critical time. isil al-nusra and other groups have all been trying to infiltrate lebanon. >> it is a serious threat. those terrorists who are now in syria. >>reporter: monday's delivery was mostly light weapons. and while these green cases containing antitank missiles may not have looked all that impose imposing the government of lebanon insists this is a game changer. some are not assured.

>> you cannot wait to use -- >>reporter: as more soldiers get deployed to a shared border with syria, they say they still don't have the weapons they need most. and they won't have them for a while. details are sketchy but many expect it could be two to three years before any helicopters or war ships are delivered. saudi arabia hoping to curb hezbollah's military might, some say time may not be on their side. during his first state visit to pack stand, china's president has signed trade agreements promising $46 billion of investment. the center piece of the package is a corridor of roads,

railways, and pipelines stretching nearly 3,000 kilometers between the countries. he was elected the president of sri lanka in february. >>reporter: they voted for a new leader 100 days ago. a choice that's brought change. it's his promise to bring this change that brought him to victory on january 8th. he campaigned to end an increasingly corrupt rule. >> this is a temporary cabinet for the 100-day program. after this there will be a general election and we'll have a permanent cabinet that will implement our long term program. >>reporter: the promise to keep

his cabinet limited to 25 was stretched to accommodate a diverse coalition and defectors from the opposition. now it stands at 40 with more than 40 deputies and noncabinet ministers. some have found relief from food, fuel and electricity price reductions. >> united all the different sections has not been easy. there have been disputes. there are personality clashes. we have to do what the country wants. the main issue is to bring change. >>reporter: the new president has won over support of the minority. for the first time in the country's history, a government expressed regret for the violence experienced by all its

people. the president went a step further returning some of the land acquired by the military to the north. his first foreign visit to india was also part of his pledge to move away from the china-centered policy of his predecessors predecessors. but analysts say they're unhappy with measures taken against those accused of corruption. >> they feel it's unsufficient. i think the population at large expected that there would have been indictments, convictions. >>reporter: one notable feature in the past 100 days is a deferent feeling of being -- definite feeling of being free.

still ahead, accused of opening fire on civilians. a new report implicates mexican police. and as u.s. cuba ties improve, both countries stop to consider the investment opportunities. >> plus the world's best tennis players are in barcelona as the build up to the french open continues. continues.

>> weeknights on al jazeera america. >> join me as we bring you an in-depth look at the most important issues of the day. breaking it down. getting you the facts. it's the only place you'll find... the inside story. >> ray suarez hosts "inside story". weeknights, 11:30 eastern. on al jazeera america. the european union has proposed a new plan to tackle the migrant crisis which

includes destroying smuggler boats and more funding for rescue operations in the mediterranean. this is the scene in sicily where a boat carrying the few migrants who survived sunday's capsize and it will arrive shortly the capital of yemen has been hit with the largest explosion since the saudi-led air strikes began. at least 46 people are believed to have died in the explosion. south africa's zulu king has condemned a wave of anti-immigrant attacks in the country and denies he was to blame duringty rally in durbin. thousands of people from north africa risk their lives trying to reach europe by crossing the mediterranean. al jazeera has spoken to one man

who made the journey. joseph set out from ghana and made it to libya but he paid people smugglers for a place on the boat. the boat was intercepted and then he was flown to rome. we caught up with him to find out his story. >>reporter: for the migrants crossing the mediterranean sea, it is a journey that represents a new life. a new start. joseph got that new life five years ago. >> they said you have entered italian waters. >>reporter: he had to get out of ghana and made his way to libya where people smugglers put him on a boat for a price. >> the first time i was lucky. the first time they promised me i was moving that day.

i went in and they didn't take me. they said that the boat is oversold. it's full. so i have to go. about one or two days later, i heard the boat sank on the sea. all of the people died. >>reporter: so you had a narrow escape? >> yes. and the people were -- they were 125 passengers. all of them died. all of them sink including the boat. >>reporter: but the boat he did board also got into trouble and had to be rescued. joseph still remembers vividly the moment he arrived in europe. >> people were very kind to us. they were happy to receive us. they checked us for four days

medication and everything. they treat us. after that they took us inside and we came to rome. >>reporter: but life has not been as kind as he had hoped. joseph takes odd jobs where he can. he barely gets by. >> i struggle to get money to feed myself. >>reporter: you struggle to eat? >> yes, struggle to eat. in italy, here a special room here. the job has been limited. there's little jobs. people are working. if you're not lucky, you just pray someday somebody will call you to work for them. >>reporter: and he has a message for those driven to risk their lives to get to europe. >> it's better for them to stop coming. they should stay where they are. >>reporter: the words of a man

who's been there, is there now. but words that many will ignore so desperate are they for that new start. in the past it's been incredibly difficult to get european countries, the 28 members of the european union to agree on a policy to deal with the migrant crisis. but do you think the shock over the sheer number of people who died in the capsize over the weekend, do you think that's enough to push them to come together and find some sort of policy? >> at the moment what we know is that there's been a statement of intention coming out of the meetings today in which it seems like they found an agreement to

restate a rescue operation. that's certainly a welcome development. i guess we have to wait to see if these ten principles become something for concrete. for now, it seems like there are few of -- that are just optional and we need to see how many resources they put in the new operation. >> do you think the fact that they're considering reinstating more patrols, does that mean that the eu now accepts cutting back on the rescue operations hasn't deterred the desperate migrants because that's what they thought would happen. >> i think that they have come to realize especially britain who was very adamant not wanting

to support the rescue operations just a few months ago that cutting back the rescue operation caused more people to die and doesn't really stop the migrants from trying to reach europe. so i think now there is a need to restart the rescue operations as soon as possible especially with the summer months coming. the problem is not just the problem of humanitarian problems. it's also a political problem. i think very few leaders can handle daily news of people dying at sea. this is what's going to happen if they continue like that. >> other idea put forward include having eu processing centers in north african countries to deal with migrants before they actually leave. is that actually feasible and do you think those countries would degree to such process centers being on their land?

>> there are examples of good cooperation in north africa before the arab springs. for example, a cooperation with problematic countries like khaddafi's libya. there's clearly a possibility for improving the relation with tunisia in relation to the management of the migration flows in the area. i don't think that libya at the moment can really provide a stable government capable to manage the flow so there is a need to cooperate with the neighbors as much as possible. the idea of launching a processing center outside was looked at a few weeks ago and we don't know yet the details of what they plan to do. it could work if -- to some

extent. the problem is that the very large majority of the migrants that are on those boats trying illegally to reach europe have genuine cases for asylum. so if those cases could be assessed before they tried to travel on very dangerous boats, that would probably save some lives and would enable people to see their cases acknowledged and be able to possibly be relocated and resettled in one european country. >> it's great to get your thoughts on this subject. thank you for joining us on the program. >> you're welcome. mexican federal police gunned down 16 civilians in an incident in january according to a report published in a mexican magazine. it contradicts officials who said only nine people died and they were caught in cross fire. the investigation accuses the

police of directly opening fire on a crowd of civilians armed with nothing more than sticks. the mexican government is already under pressure from allegations of army and police killings. >> why are we going through this process? to bring peace and reconciliation to columbia or drive to insurgencies to the tribunals. we're discussing in the presence of active military members elements of that definitive

cease fire. we've advanced so much but we're not going to get there under the pressure of the attacks. we're not talking about agreeing to imperfect and fragile truces. that's not going to happen. >> where does all this leave the peace process right now? >>reporter: that's a big question. the good news is that both sides seem to be committed to continuing the talks and reaching a final agreement. there's no doubt though that a lot of damage has been done with this attack. there's a lot of rage really in the public opinion here and members of the military. it is directed towards the farc but also towards the president here who was booed and jeered yesterday at a public event by members of the military and family members of the military. and that's really unprecedented here. so what we're hearing today is

that they do want to continue but at the same time it will be very difficult to rebuild the kind of confidence that existed and that was slowly built in the last few months with a lot of positive announcements. >> clearly things are better than they were a couple of years ago but what do most columbians feel about the issue? do they believe that the peace process should continue? >>reporter: a majority of columbians are still hoping that this will go through. the issue here is that they don't believe the farc. they've been used to you know going through previous peace process that then failed under the pressure of military actions, farc attacking the infrastructure in the country or the military and this is exactly what seems to have happened last week. now, the farc are saying that they will continue and maintain their cease fire as long as they're not subject to a

permanent siege by the military and what they mean is that as long as military operations ground operations continue incidents like the ones that happened last week could occur again and that's really the tricky point here. how much patience do columbians have and what will happen if more violence comes in the next weeks and months. >> thank you. it is more than four months since president obama and his cuban counterpart raul castro announced they would normalize relations between the countries including taking cuba off the list of countries supporting terrorism. >>reporter: the americans are coming. but not in the way the cuban government had for so long anticipated. these visitors are here from a

washington organization to talk about mutual understanding and political cooperation. >> obama finally came to the realization if do you the same thing year after year for 50 years, it doesn't work maybe you should try something new, something else. and so we are now trying something else. at long last. >>reporter: many on both sides of the florida straits are anticipating and planning for substantial financial investment. >> the tourists are already here but this is just the beginning. plenty more visitors will be coming from the united states but they won't all be following the tourist trail. many are coming to invest and in a way that cuba has not seen for more than 50 years. but the u.s. economic embargo remains restricting growth of the cuban economy but not as

intended toppling the government. intense negotiations are underway in havana and washington to have it lifted. in the meantime preparations are being made. >> they come as tourists but when you talk to them you find they're lawyers, people working for american companies asking about the opportunities available in cuba. >>reporter: the cuban authorities have been paving the way with developments of this container port west of havana for instance. while many smaller cuban businesses are keenly anticipating the changes. >> we're not happy just having foreigners here. we want them to come and meet and mix with cubans from every social and cultural background and we as cubans cubans want to know people from different countries and cultures to talk share and exchange ideas. >>reporter: for most however, not much has changed. not yet. with all change comes

uncertainty about what will be lost as well as what will be gained. the americans are coming. while cubans wait with great expectations and some fears over what they may bring. >> the oil company chevron will not have to pay compensation after an u.s. court rejected an appeal by residents of a rain forest in ecuador. they are accused of dumping toxic waste in the remote northern region of ecuador. they were ordered to pay compensation in a court in ecuador a few years ago. they've now won two cases in the u.s. saying the court was bribed and it is unsound. a high school student is

accused of killing his teacher and four other students in a barcelona school. >> he didn't have problems but he was kind of a loner. others picked on him. he lost his mind. he's been talking about weapons in previous days. he had a list of people he intended to kill and then he did it. coming up we're going to travel to -- the boston marathon brings top athletes and spectators out on to the streets. that's coming up in a couple of minutes. minutes.

time now for sports. >> thank you very much. tens of thousands of people have taken part in the boston marathon. security was high after the bomb attacks on the race two years ago that killed three and injured 264. the races were dominated by kenyan and runners from ethiopia. in the women's race kenya held off ethiopia with the win. on tuesday the trial resumes of dzhokhar tsarnaev.

>> i am happy to win number one. we strong boston 2013. >> now a 20-year-old has died -- match between teams in calcutta. she suffered a head injury while colliding with a teammate. she was captain of the team and short listed for the world cup last year. earlier this year, ausaen phil hughes died after being struck in the neck by a ball during a state match in sidney. >> he had a severe traumatic brain injury which gives rise to swelling of the brain which can compromise his respiration and cardiac activity any time.

for that reason he was kept in the icu to see any immediate change and take appropriate measures. unfortunately, his cardiac arrest occurred and we took all appropriate measures including a pace maker but he unfortunately succomed to his injury. the european champions league now where the final lineup will be decided this week. munich must win on tuesday.

>> i'm optimistic but i'm realistic. it won't be easy getting a 3-1 score in the quarter finals but i'm still optimistic as i was so i really believe we can get through this situation. >> also on tuesday barcelona is expected to complete the job against paris thanks to lewis suarez. he appears to have settled in. >> they say you stay the same. you play liverpool. outside the pitch. i am so happy with that. a lot of joking and they are happy and i am so happy with

that. >> he had an impeccable year in 2011 as well as this one in 2015. the rest of the players have to accept that at the moment he's the world number one with all he's achieved this year. i have to get back to a very high level to face him on the courts.

it looks as though they'll have to do it without aaron kruden after a ligament injury in his knee. his replacement kicked the winning penalty. one of the nfl's most highly rated young quarterbacks before a dip almost ended his career but tim tebow has been signed by the philadelphia eagles. he made a name for himself playing with the denver broncos in 2010 but after joining the new york jets his career stalled and was cut from the patriots roster in 2013. finally it's not often i get

to segue into a sport with the name segue in its title. segue polo involving teams from finland, germany, and barbados. it involves motorize scooters. it's a relatively new sport. >> this is a lot easier than horse back i bet you because i've tried the horse back version and it's impossible. all right. now eastern china is largely considered to be the birth place of the kite and this year at around this time thousands flock the city for an international

kite festival. >>reporter: a swath of color against gray skies. a sign of better days ahead. nothing can stop them from ushering in the spring. it's where kites originated thousands of years ago as an instrument of war but it's a sport and a source of joy now for enthusists. he comes from a long line of kite makers who kept the tradition alive. in the 60s it was deemed impure as part of a cultural revolution. >> the difference is overseas they normally use big blocks of color and focus on flying while chinese flights focus on shape and paintings. >>reporter: it's a traditional art form that he has turned into a business using only the strongest bamboo and the finest paper and silk as acanvas.

when completed, each kite tells a story with shapes and colors symbolizing everything from harmony to prosperity to long life. they become flying works of art. tens of thousands come here every year for the festival. they're all vying for the honor of being recognized as a kite master. anyone can learn to fly a kite but it takes experience and special skills to master it to learn to dance with nature with grace, beauty and longevity. the dragon symbolizes china itself and there's nothing more exhilarating for many here to look into the sky and see a master piece. once a year it's a giant canvas celebrating their heritage. and that's about it for this particular news hour. thank you for watching. join me again in a couple of minutes. bye bye.
