hello, my name is tom donkin. welcome to bbc news, broadcasting at home and around the globe. here's our top stories. with tensions high in the korean peninsula, the north tries, and fails, to launch a test missile a day after it paraded its newest military hardware. voters in turkey go to the polls in a referendum on whether the president should be given new powers. a suicide bomber targets a convoy of buses carrying syrian evacuees — more than 100 people are feared killed. and thousands of americans take to the streets, demanding that president trump release his tax returns. north korea has made a failed attempt to launch a missile a day after it issued a warning to the united states that it was ready to hit back

with nuclear attacks amid escalating tension in the region. the pentagon confirmed the test, saying the missile blew up almost immediately. south korea condemned the test, saying it threatens the whole world. the launch was carried out around dawn from sipho, a site on north korea's east coast where the country has a shipyard. steve evans has more from seoul. think of all the images that came from pyongyang 2a hours ago of these fows from pyongyang 2a hours ago of these rows of rows of the most fearsome looking missiles with pyongyang showing its strengths and then a day later, a damp squib. a dud. north korea often test missiles and they are getting better at it. but the failure rate is still very high. so it puts a bit of reality into this situation. there is no doubt the

tension here is rising. the american military president, naval military presence, is being bolstered with the carrier group headed this way of the carrier group headed this way of the vice president mike pence is on his way here at the moment to discuss what to do about north korea, but the failure indicates they haven't yet got a reliable means of delivering any kind of warhead, let alone a nuclear one, with absolute effectiveness and certainty. and the fact that this test failed, the fact that the vice president of america is due to land inafew president of america is due to land in a few hours from now and the fact that donald trump has taken a tough sta nce that donald trump has taken a tough stance on north korea, some comfort to the people in south korea? well, the thing about seoul is that people go about their business, there is no sense of panic buying or people wondering how to get out of the city. because they've lived with this situation, all south koreans

have lived with this situation since 1953. the situation of absolutely fierce rhetoric from the north about destroying the south. which never turned into out and out war. it sometimes turned into military action but not out and out war. this may be different. there are clearly much more advanced in the potency of their arsenal, they have tested nuclear warheads five times and north korea is ready for another test that people assume it's not going to happen. what we do not know is what president trump's policy yea rs. is what president trump's policy years. his words indicate that he will not allow, it will not happen, the north korea gets the ability to strike the us. but the briefings from the administration recently indicate that the policy may actually turn out to be pretty well

what the obama policy was, which is squeezed and maybe negotiate if there is an indication that north korea is leaving room for negotiation, would move on the nuclear is you. so we do not know what mr trumbull do but player as basically more of the same —— what mrtrump will basically more of the same —— what mr trump will do. life to turkey now wet holes have opened. not much action but the polls have indeed opened and as you can see local time is just after 7am where the first voters, some 55 million people, are eligible to vote in the referendum on whether to grant turkey's president over one more sweeping powers. —— over one in s double, the polls will open in about an hour

we re polls will open in about an hour were from now. you polls will open in about an hour were from now. you can see polls will open in about an hour were from now. you can see the vast scale of this vote has just begun. we will see much more people coming out onto the streets to vote as they progress. a bitter campaign has been fought in the country so far, is a correspond reports. a divisive campaign has ended, and turkey now faces the biggest political choice in its modern history. both sides made a frantic push to the end. voter turnout will be decisive in the outcome. the yes side believes a stronger presidency will make the government more efficient. if they win, the president will be given enhanced powers to appoint ministers, choose the newjudges, the prime minister role will be abolished, and he will gain the ability to dissolve parliament. a human chain stands here in defiance. they say the reforms would remove parliamentary checks and balances, and they have already destroyed turkish democracy.

it has been a dramatic 12 months in turkey, with an attempted coup and 500 dead in terror attacks. the government says a stronger leader could save them. critics say he has already failed to keep them safe. a geopolitical crossroads. turkey is deciding its future. the outcome will be felt far beyond its borders. mark lowen, bbc news. to syria, where a huge car bomb has hit a convoy of buses carrying evacuees from two government—held towns. the passengers had been waiting at a transit point travelling from foah and kafriya to the west of aleppo. the delay was caused by rebel groups raising concerns —— the syria white helmets say they have recovered more than 100 bodies. richard galpin reports. in the immediate aftermath, a man runs towards the site of the huge explosion, filming the horrifying scenes around him.

it is believed a suicide bomber carried out this attack, reportedly driving a van carrying aid supplies. translation: i can't describe it, i am speechless. there are dead people everywhere. you can see dozens of burnt—out cars, bodies everywhere. emergency staff and opposition factions are evacuating the wounded and the dead. the target was this convoy of buses carrying hundreds of men, women and children finally able to leave their villages which had been under siege for years in syria's continuing civil war. since last night, the convoy had been held up on the road near aleppo because of a hitch in the deal agreed between government forces and the rebels for the evacuation. that left everyone here very exposed to an attack. with so many killed and injured in this bombing, there are fears

of revenge attacks and an end to further agreements to get people out of other besieged towns and villages. for those who survived this attack, the aim now is to get them to safe areas as quickly as possible. some are already reported to be getting back on buses, leaving the horror of this day behind them. richard galpin, bbc news. tens of thousands of people across the united states have marched in more than 100 cities to demand that president trump releases his tax returns — something he has refused to do. some protesters carried huge inflatable chickens, suggesting the president was scared to release the data. president trump's predecessors over the last a0 years have all released their tax returns. greg dawson has more. fanfare. with little chance of the president himself discussing his taxes... alright, cut it out!

fanfare abruptly ends. ..protesters in the nation's capital opted for the next next thing. this was an example where imitation was not meant to flatter. what's the big deal about my taxes? 0k, since you guys are my supporters... releasing the taxes! piles of shredded mock tax returns were thrown into the crowd. 0rganisers claim the protests have been taking place in over 150 places in the us. chicken dance song plays. in chicago, crowds took part in a chicken dance, suggesting donald trump is too scared to release his returns. singing: # enjoy the resistance!# the president broke a long—held tradition by not releasing his paperwork during his campaign, and these protests were timed to coincide with the mid—april deadline for americans to file their tax returns. if taxation without representation is tyranny, then representation without taxation is authoritarianism. we deserve democracy. cheering. in manhattan, several

thousand lined sixth avenue, marching towards one of donald trump's hotels. these people say without his tax returns, it is difficult to know who the billionaire president has had dealings with as a businessman and if there are any conflicts of interest. donald trump says he cannot supply his returns because they're being audited — something the federal tax authorities say is no bar. we're living in a time where honesty has no currency. and i think because of that, it's kind of all we have. and the only way to really penetrate this administration is to take to the streets. the president's supporters point to a recently leaked 2005 return showing donald trump paying $38 million to the tax man, and many say the issue simply does not matter to them. in berkeley california, rival pro— and anti—trump rallies descended into a brawl with more than a dozen

arrested as fistfights broke out. another reminder of how donald trump continues to be a president that polarises his country. greg dawson, bbc news. stay with us on bbc world news. still to come — we'll find out how an ancient type of ball game is keeping mexico's modern footballers on their toes. pol pot, one of the century's greatest mass murderers is reported to have died of natural causes. he and the khmer rouge movement he led were responsible for the deaths of an estimated 1.7 million cambodians. there have been violent protests in indonesia where playboy has gone on sale for the first time. traditionalist muslim leaders have expressed disgust. the magazine's offices have been attacked and its editorial staff have gone into hiding. it was clear that paula's only contest was with the clock

and as for a sporting legacy, paula radcliffe's competitors will be chasing her new world best time for years to come. quite quietly, but quicker and quicker, she seemed just to slide away under the surface and disappear. this is bbc news. i'm tom donkin. the latest headlines: with tensions high in the korean peninsula, the zero has tried and failed to launch a test missile a day after it paraded its newest military hardware. turks are voting in the east of the country in a referendum that could scrap the post of prime minister and expand the powers of

president erdogan. that's stay with that story. i am here with berza simsek from the bbc‘s kertes service. but we go to these live pictures in 30, where the first polling stations have opened. —— in turkey. this is very much a —— cross rhodes for the country. berza simsek, i did so this was a pivotal time for the country. just gives an indication of what voters will see when they walk in to vote, on their cards. —— crossroads. what will the question be? the question is yes or no to the constitutional changes. the changes are composed of 18 articles. and basically, when they choose the option yes or no, which are in different colours, yes means yes, i

agree with the constitutional changes, and "no means no", i do not agree with those changes. and when we look at the constitutional changes, it limits the power of the parliament and gives more power to the president. —— no, that means no. soa simple the president. —— no, that means no. so a simple question, but a collocated answer for the country. —— complicated. collocated answer for the country. -- complicated. it is basically a complicated constitutional change. for example, as you said, it is really difficult, and people will not appeal to read it on the ballot papers. when we look at what is on the constitutional changes, in detail, for example, the president will be able to appoint top public officials, including ministers. he will be up to a sign vice presidents and the prime ministry office will

be abolished. and the president will be abolished. and the president will be able to abolish the parliament if he or she wants. and to ask for a new election. the process of this is going to be quite a logistical challenge, because there are a huge number of people voting. yes, 55 million people will be voting. and the voting, as you said, has started in the eastern part of turkey. later, it will start in the west. there are more than 167,000 ballot boxes all over the country. we expect it to go until 1a gmt. and then we will start seeing the results. thank you very much for joining us, berza simsek from the bbc turkish service. an international footballer from panama has been shot dead in the

port city of colon. two other people we re port city of colon. two other people were injured in the shooting. panama's president has promised to track down those responsible for the shooting. police in adelaide sa five—year—old boy has died after his head got lodged between a wall and a table fixed to a slow—moving floor ina table fixed to a slow—moving floor in a revolving restaurant. the child was critically injured in the incident at the sun dial restaurant at the top of the westin peachtree plaza hotel. he later died in hospital. his death has been ruled accidental. now, more on our top story, the failed launch of a north korean missile. earlier we spoke to michael duitsman, research associate at the james martin centre for non—proliferation studies. and i asked him more about what we know. pacific command said it

exploded almost at launch, so we are unlikely to find out what sort of missile it was any time soon. it was launched from near the sinpo area, which — so we don't really know — it could be any missile in their arsenal, but we do know that there is a large naval base in the town of sinpo, that is associated with their submarine launch ballistic missile programme. it might be one of the missiles associated with that programme. this port of sinpo is the site of a quite recent failed launch, as well, isn't it? yes. actually, less than two weeks ago, they tried to launch another missile, and it reached a high altitude, but did not go very far down range. it followed a very strange trajectory and appears to have spun out of control before destroying itself. are you seeing this as a more frequent occurrence, these tests? albeit they fail, but iss it a sign that they might be advancing their capabilities? well, actually, compared

to previous years, last year, they conducted six tests. but the year before that, they had already conducted 12. so the cadence is not actually that different from previous years. although they are probably testing new capabilities. right. and i'm sure you were watching the military parade in pyongyang. did we learn anything new from that? well, we learned quite a bit. they showed us more new technology than they had in any previous parade. in terms of what? so they shows us, especially at the end, the very large missiles, the canisters, which indicate that they intend to pursue long, probably intercontinental range solid fuel missiles. so, in your mind, that is a deliberate display of what they are capable of, in terms of other military parades, has that showed that their up—to—date, their newest hardware?

yes. definitely. just showing us what they are working on, what they intend to develop, even if it isn't currently ready. football is incredibly popular around the world. there are few places that fans are more fanatical about the so—called beautiful game than in latin america. but there is an earlier type of ballgame in that region that predates soccer by thousands of years. and in mexico, the national championship has been taking place. the bbc‘s tim allman has more. in the shadow of this ancient city, a match of the day that has been 3,500 years in the making. spectators came from far and wide to the teotihuacan pyramids for the mesoamerican ballgame. sometimes known as "ulama," the rules can very. but here, two teams face each other using their hips to keep the ball moving.

fail to do that and your opponent gets a point. both men and women can take part in something that is much more than just a sport. translation: what i want is for us mexicans to realise that we have a rich culture. we ought to be proud because we are the first country in the world to have a game like this. the motion of the ball is supposed to symbolise the rotation of the sun for the aztec, olmeca and mayan people. this isn't just a pastime, it's history. translation: it is something i was truly proud of, being able to be part of this, and ensure that mayan roots do not die off, and that we are the generation that revives this remnant from the mayans. this is a game that predates columbus and the birth of christ. ulama, a sport where hips don't lie. tim allman, bbc news.
