turkey's president, rejep tayyip erdogan, has declared victory, in a controversial referendum granting him sweeping new powers. he said the country had turned a "new page," in its democracy. but opponents say the result amounts to a one—man rule, with the president now able to abolish the role of prime minister, and if necessary, dissolve parliament. it was a close vote, with widespread support for the constitutional changes in rural areas, but with many rejecting the proposals in the bigger cities. the opposition are alleging voting fraud and say they'll challenge the result. our world affairs editor, john simpson, reports from istanbul. tonight, the victors were out in force, celebrating as though they had won by a big majority, instead of by a whisker. in fact, here in istanbul, and in turkey's two other largest cities, izmirand in ankara, the capital, the no campaign seems actually to have won.

the worry is that the result has been too narrow to settle anything for good. the bangs are notjust fireworks. those are guns being fired. the fact is that there is a big underlying level of nervousness and anger here, which really the result of this referendum, being so close, hasn't done anything to calm down. "tayyip erdogan will be a world leader," says this man. no, no, no, no. this is history, this is history! however slight his majority in the referendum, president erdogan has taken the decision to push through his far—reaching constitutional changes, and deal with any consequences. translation: today, the decision taken by the turkish public

is a historic moment. this is not an ordinary day. these very serious changes are underway, for turkey's future. then he went out to speak to some of his supporters face—to—face. they chanted, bring back the death penalty, and he seemed favourable to that. his argument all along has been that only a really strong presidency can galvanise turkey into being successful and wealthy, so he is getting rid of the old constitution‘s checks and balances. he is giving himself the power to hire and fire the country's judges, and he has made it possible for himself to stay as president until 2029. there have been one or two small opposition demonstrations, but he has stamped down so hard on his opponents in recent years that they are reluctant to come out

on the streets in any great numbers. the yes campaign might not have won the popular vote in the capital, ankara, but there tonight, it had its celebrations all carefully choreographed in advance. this has indeed been a day on which history was made, but it is likely to cut turkey off further from its old allies in western europe and america. what we have seen today looks like a major change of course. we will take a look at what the referendum result means for turkey's relationship with europe. remember, for a long time, turkey wanted to join the eu. president erdogan‘s victory has brought caution and warning. the european commission said this. the council for europe,

of which turkey is a member, said this. remember, turkey's new proposed constitution means the president could intervene in the justice system. the danish prime minister said this on twitter. the majority has the right to decide, but i am quite concerned about the new turkish constitution. the austrian foreign minister said this. collaboration with the eu will be more complex. a number of residents of istanbul have been protesting. this is a video from ankara. the

opposition and ak party were both there. police were called to deal with that. what next for turkey? you have one side of the country tonight that is jubilant, that feels it has clinched victory, and it has given president erdogan — given him sweeping new powers. the other side of the country that is not accepting this result, claiming massive voting irregularity, saying that 1.5 million votes which should have been declared invalid, because they lack the official stamp of the electoral supreme board, were actually given to the yes side, and that electoral observers were blocked from south—eastern polling stations, in the south—east of the country. they have vowed, the opposition, to challenge this at the high court, at the electoral supreme court. so really, in a sense, in terms of the stability of turkey in the short term, going forward, this is possibly the worst possible result, going forward. and really, when you look at the breakdown of the votes, the more rural, higher side of the country voting in favour of president erdogan, the more cosmopolitan,

western—looking cities voting against him. turkey is split down the middle, more polarised than ever. and more on the turkey referendum result later in the programme. mike pence has visited the demilitarised zone in korea. america says it's working on a "range of options" with china, as tensions continue to grow over north korea's nuclear and missile programmes. pyongyang attempted to test fire what's thought to be a medium—range missile this weekend, but it blew up shortly after take off. our correspondent, john sudworth, is in the north korean capital, where his movements are being closely monitored. this flower show, like almost everything else in north korea,

is dedicated to its ruling family. this is the stand of national defence industry... and this display is in honour of their abiding obsession, missiles. is it a little strange to have rockets and missiles in a flower show? no, not strange at all. there are reports that there was a missile test... yeah. ..and some suggestions that it failed. have you heard these reports? this is not a failure. we will win, and we will have greater successes in the future. there has so far been no mention of the missile on north korean tv. but it is true, every launch, failure or not, takes the military one step closer to its goal. the timing of the latest missile test is significant, coming just a few hours before the us vice president, mike pence, arrived in the south korean capital, seoul. it is a message of defiance from here in pyongyang. its quest to become a fully—fledged nuclear power continues. at its big military parade, it put some of its newest missiles on display. the decades of threats and sanctions

against north korea have clearly done little to stop it. mr pence's talks will focus on trying to find something that will work. senior administration officials say military options are still on the table. the president has made clear that he will not accept the united states and its allies and partners in the region being under threat from this hostile regime, with nuclear weapons, and so we're working together with our allies and partners, and with the chinese leadership, to develop a range of options. at pyongyang's zoo, there was a relaxed, holiday atmosphere. the looming crisis seems far from anyone's mind. north korea appears confident that president trump's threats will turn out to be hollow, and that he will conclude, like others before him,

that war carries far too many risks. john sudworth, bbc news, pyongyang. the number of people thought to have died in saturday's bomb attack in syria has risen to 126, including 68 children, that's according to local activists. they were among bus loads of civilians being brought out of two pro—government towns in the northwest, that had been under siege. the blast happened on the outskirts of aleppo. a warning that this report from our diplomatic correspondent, james landale, contains some distressing scenes. they were heading for what they thought was safety. thousands of civilians from government—held villages had been under siege by rebel forces for two years, just a short bus ride from aleppo, and a better life.

but then this. a massive suicide bomb attack, a vehicle supposedly carrying food, packed instead with explosives, devastating the convoy of buses and cars. a potato truck, as they were very hungry, comes and offers for the kids potato chips, potato bags. so the kids, who were very hungry, they left, some of them left the buses, went to the truck, and as soon as they approached the truck, it exploded. among the 126 dead were 68 children, according to british—based activists who monitor the conflict. hundreds of others injured in the attack were rushed to hospital in aleppo. it is still not clear who was responsible for the attack, although local islamist rebel groups

have denied any involvement. the people travelling in these buses were part of a deal between government and opposition forces to evacuate civilians from towns besieged by both sides. they were attacked as they waited for another convoy to get going in the south, evacuating civilians from rebel—held areas. but an attack like this, that left so many dead, will raise doubts about whether there will be more evacuation deals in the future. the remaining survivors in the convoy continued theirjourney on to aleppo in relative safety. the united nations condemned the attack, and urged all sides to ensure the security of evacuees. but there are already fears that civilians in rebel—held areas may now face revenge attacks. stay with us on bbc news. still to come: paying tribute to one of the greatest comic actors of the 20th century. why hundreds of charlie chaplins got together in switzerland. 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: ‘yes' campaigners in turkey celebrate as they claim victory in the referendum. president erdogan says changes to the constitution will now go ahead. for more on turkey's referendum, i spoke withjonathan schanzer — senior vice president at foundation for defence of democracies — and i asked him if president erdogan‘s victory may distance turkey from its traditional allies in the west. well, i think that horse has already left the barn, so to speak. we have already seen that nato has not been terribly pleased with turkey, in the way that turkey, for example, refused to allow the anti—isis coalition to access their base for many months. they of course also allowed for the 550—mile border with syria to remain very porous, so the jihadis could infiltrate. it really did look like turkey had turned a blind eye

to these problems. so you have a lot of european countries that are unhappy about that, unhappy about turkey's releasing of refugees into europe, and using that as, really, a threat. i think we have already seen a distancing there, and we have seen a flirtation on behalf of erdogan with putin, and of course with iran, and other countries in the middle east. so it really does appear that we are looking at a changing of turkey, that we are losing it, in some respect, and it is becoming more and more like a middle east country, and less like a european one, unfortunately. with me is oyku altuntas from the bbc‘s turkish service. thanks forjoining us. this was not the resounding victory that president erdogan thought he would have. the expectation was that the yes voters would gain much higher

voters but when we look at the poll results we have received before the it was never more than 60%, despite one poll result but it was around 52. it wasn't such a big surprise but akp officials today said they expected higher yes votes and it seems to be a surprise for them as well. maybe surprisingly to some, istanbul, ankara and other big cities went for a no vote. what of that talk about the democratic ' 7 that talk about the democratic split? when we look at the numbers, for instance istanbul, 51% said no active uncorru pt a for instance istanbul, 51% said no active uncorrupt a similar percentage but in its mayor, it is higher than 60%. ——

percentage but in its mayor, it is higherthan 60%. —— is percentage but in its mayor, it is higher than 60%. —— is hard to predict how it is connected to the alleged polarisation —— izmir. and what it would lead to in terms of these dividing political discourse. whether this leaves the opposition? what can they do to contest the results ? what can they do to contest the results? the main controversy here is that the supreme all editorial board said today that they will accept the votes without the official stamp and the main opposition said, as they announced quite late as well, it is not acceptable. they want 60% of these votes to be recounted. just quickly, how long will it take for this to be implemented? it's very hard to predict now but sources with indie

akp said it could take around six months to implement some laws. we'll have continuing coverage on turkey here on bbc world news. until then do go to our website for more background including why turkey has been having this referendum, as well as written analysis from our correspondents. that's all at bbc.com/news or download the bbc news app. a rescue operation is under way in north—western iran following heavy flooding. according to state media at least 30 people are reported to have died. others are said to be missing following torrential rains. areas of east azerbaijan are reportedly, the worst hit. but several other provinces are effected as kasra naji reports. northwestern iran has been badly hit. many rivers have burst their banks, taking roads, bridges and houses with them. about a dozen or so people

at least an hour before departure. sunday would have been the 128th birthday of hollywood legend — charlie chaplin. to mark the day hundreds of people gathered at the chaplin museum in switzerland — the country where he spent his final years. while there, they celebrated his work and his ideals. the bbc‘s tim allman reports. ragtime jazz plays charlie chaplin spent the last 25 years of his life at this estate. so here seemed an appropriate place to celebrate him and his work. the little tramp. lots of them. his most famous creation.

a character, a performer that seems timeless and strangely up to date. translation: if you look at all the tensions that are shattering the world right now and if you look at a movie like the dictator or even modern times, the issues — they can be still very relevant. at one point in the early part of the 20th century, charlie chaplin was just about the most famous man in the world. his films, loved by millions. his politics, a lot more controversial. eventually he was barred from returning to the united states. in some ways he had become a citizen of the world. i think it is his character, you know? the little tramp. it is universal. everyone has a little tramp inside themselves so they recognise themselves. this was a gathering to help mark his work and his values. appropriate that they formed a star, because that is exactly what he was. the bodies of five former

the forecast is one that benefits those on break. not much rain around, but some dry and quite sunny weather to enjoy at times. turning warmer, after a chilly start overnight. will still stay frosty, especially in the south, and quite cold out there at the moment. as we start the day, we have high pressure to the west of us, low pressure to the north—east, the northerly pressure bringing cold air notjust to us but to a good part of northern and eastern europe as well. now, most will start dry and bright across the northern half of the uk. so let's start the forecast for easter monday here. there may be one or two showers across parts of scotland, but a brighter day to begin with across northern england, and indeed northern ireland. northern ireland should stay dry throughout. but showers and rain, sleet to lower levels. sleet and snow in eastern scotland will drift away southwards through the day, followed by much, much sunnier conditions. whereas further south we start off with the cloud, and maybe the odd spot of light rain and drizzle for parts of wales, the midlands, into the

south, in particular. there will be very few showers through the day. most will avoid them. if they do come your way, they will be fairly fleeting. and notice how the clouds break up, more sunshine developing through the afternoon. so again, just about across—the—board, more of you will see the sunshine on easter monday than you did through sunday. these are the temperatures to finish through the afternoon. lighter winds further south. in the sunshine, should feel reasonably pleasant. we finish the day with lots of showers in northern england, and they will drift down the eastern areas to take us through the night and into tuesday. as they ease off, the skies clear, the wind falls that little bit lighter, temperatures will plummet. for those of you in the northern half of uk, it will be the coldest night of the week. away from the towns and cities, temperatures —5 to —7 in some parts of scotland, most just about avoiding frost across the south. probably a bit too much breeze into tuesday, could bring the odd shower, and we could see the odd spot of rain in the hebrides a bit later. but for the commuters, a cold start to tuesday,

but for those on holiday it is looking like a good day. most places dry, with lots of sunshine. a bit of a fresh spring day, but that sun is strong enough to make it still feel reasonably pleasant. then, as we go through wednesday, a high establishes itself across the southern half of the uk. we will see westerly winds pushing into the south of scotland. that will bring the cloud, the odd spot of rain, that will push into parts of northern ireland, as well, keeping the temperatures up here on wednesday morning. but further south, this will be a colder start to the week. one or two of you could get down to —6 or —7. couldn't rule out the odd shower to the south and east, but most places will be dry and fairly sunny. goodbye for now. the latest headlines from bbc news. officials in turkey have announced that president recep tayyip erdogan has narrowly won sunday's referendum on his plans to substantially increase the powers of the presidency. with more than 99% of the votes counted, the "yes" campaign won just over 51% of the votes. a senior member of the trump
