a better future. turkey and the netherlands are locked in a furious diplomatic row after turkey's president erdogan described the dutch as nazi remnants and fascists. the dutch prime minister said mr erdogan‘s remarks were crazy. the row worsened after the dutch government prevented two turkish ministers from addressing a rally in rotterdam and turkey's foreign minister was stopped from travelling there. we have two reports, the first from our correspondent

mark lowen in istanbul. they love his nationalism, his bluntness, his standing up to the west, and today, recep tayyip erdogan doled it out. after his foreign minister was blocked from landing in the netherlands, president erdogan hit back at the dutch, his diplomacy typically undiplomatic. translation: they don't know anything about politics or international diplomacy. they are very nervous, and cowards. they are nazi remnants, they are fascists. the foreign minister had wanted to rally turkish voters in the netherlands before a referendum on boosting mr erdogan‘s powers. but, with the dutch election next week, the government there feared it could provoke tension, and feed the anti—immigrant geert wilders. on the campaign trail, the dutch prime minister said he wouldn't give in to turkish blackmail. this morning, on television,

he made clear that he threatened the netherlands with sanctions. and of course we cannot negotiate with the turks under such threats. so then we decided, the foreign minister, the french prime minister and myself, in a conference call this morning, that it was better for him not to come to the netherlands. his country having been occupied by the nazis, mr rutte reacted bluntly to the fascist comparison. it's a crazy remark, of course. i understand they're angry, but this is, of course, way out. germany, too, was branded nazis by mr erdogan, after it blocked turkish rallies, unprecedented language among nato allies. president erdogan has an advantage with europe, turkey the most active route for migrants, and its role crucial to stemming the flow. he has used it as a bargaining chip, but the eu is getting increasingly frustrated with the turkish strongman. this is a classic erdogan political

tactic, painting turkey as the victim of western oppression, and himself as the protector of national pride. he thrives when he and his country are seen as the underdogs, and this growing stand—off with europe will rally his nationalist support base, which he needs for a referendum victory. so vintage erdogan, pleasing his supporters, horrifying his opponents, and reiterating the sense that polarised turkey is drifting ever further from europe. mark lowen, bbc news, istanbul. as we reported... in the last hour dutch police have broken up a pro—erdogan demonstration at the turkish consulate in rotterdam. earlier dutch authorities detained a turkish minister to prevent her from addressing a rally there. family affairs minister fatma betul sayan kaya had travelled from germany to rotterdam. she is now being escorted back to the border. sarah corker reports. this diplomatic row is intensifying.

four hours hundreds of pro— turkish supporters have surrounded the turkish consulate in rotterdam chanting their president's named. this is a show of anger and frustration. police were seen stopping the turkish family minister and her convoy from driving to the consulate in the city. she had travelled from germany to rotterdam by car after the foreign minister was refused entry to the netherlands earlier in the data. she was seen negotiating with police and dutch broadcasters have reported she was detained to prevent her from addressing a rally in support of the president. her convoy is being escorted back to the german border by dutch authorities. she later tweeted: police circled the con shilat with

officers and barriers but protesters refused to go away —— consummate. translation: we are here to welcome oui’ translation: we are here to welcome our minister, we're not here to demonstrate. and the mayor of rotterdam issued an emergency order in an attempt to contain the demonstration and secure the city centre. sarah corker, bbc news. so why are turkish officials taking these referendum rallies in europe so seriously? well, the numbers say it all. over 6.5 million turks live in europe. around 3.5 million of them live in germany. and around 500,000 live in the netherlands. and the turkish election commission says that in the most recent election, over 2.8 million turkish citizens were eligible to vote at a turkish embassy abroad. that may prove crucial in winning president erdogan the powers he seeks. a little earlier i spoke to seref isler from the bbc‘s turkish service and asked him why he thought president erdogan

was being so outspoken. the referendum is coming up to give him more executive prowess as president, the presidential post in turkey is largely a ceremonial position. turkey is run in a parliamentary democracy system. this referendum would give him more executive powers and he is perhaps trying to ensure that he gets the full vote of turks living abroad. now, in terms of the rhetoric he's been using, these rallies have to ta ke been using, these rallies have to take place in these countries to get the attention and perhaps get the support of turks living there. once one has been blocked it is almost like a dent in their show of strength. so he prefers to up the rhetoric slightly in a way complaining to the turkish domestic voters about the way turkey's been treated internationally, and then

pushing the ball perhaps onto the other court and saying, you know, what are you going to do now? similar gatherings banned in austria, germany and switzerland. what's really at stake here for him? at sta ke what's really at stake here for him? at stake really is his political career, his reputation. this is as serious as it gets because we are talking about someone, not from just a politician's perspective, but perhaps as a human being as well, someone perhaps as a human being as well, someone who has been in powerfor incredibly long. his party was elected in 2002, end of 2002 and he became prime minister around 2003. he has been the leader of turkey for an incredibly long time, over a decade now. to lose a vote after such a long time in powered certainly be a dent in his reputation and perhaps for that reason he absolutely needs to get this vote if he seeks to continue

his role... for one thing, his position as the leader of turkey, but also his position as perhaps one of the strongest leaders of turkey in the modern era. just briefly if you would lastly, dutch media reporting turkish family affairs minister managed to get into the netherlands and has been stopped and now escorted back to germany. that is one of the latest twists in this bizarre saga that has been unfolding. the family affairs minister, she said she would be travelling to the netherlands by land after the plane of the foreign minister was not given permission to land in the netherlands. there have been lots of conflicting reports over the day about what was going on with the family affairs minister but what is crucial is that the diplomatic situation, that in itself causes, because what kind of passport would a minister have? it would probably be a diplomatic

passport and then of course you have all sorts of diplomatic immunity situations arising as a result. and for more analysis on this diplomatic spat and what's behind it, you can go to our website at bbc.com the world's facing its largest humanitarian crisis since 1945. that's the assessment of the united nations which says more than 20 million people face the threat of starvation and famine in four countries in africa and the middle east. £3.5 billion are said to be needed byjuly to avert disaster. this report from our world affairs correspondent richard galpin contains images you may find distressing. for months now, it has been known that millions of people, including young babies like juda jaba, in yemen, have been starving. she was just four months old when a bbc team met

her in december. across yemen, hundreds of thousands more children have so little to eat they are struggling to stay alive. and the threat of mass starvation is affecting three other countries. this is a refugee camp in south sudan, which, like yemen, has been torn apart by conflict, families forced to flee their homes, and left with little to eat. already a famine has been officially declared here, with almost half the population in urgent need of help. we stand at a critical point in our history. already, at the beginning of the year, we are facing the largest humanitarian crisis since the creation of the united nations. now more than 20 million people across four countries face starvation and famine. without collective and co—ordinated global efforts, people will simply starve to death. of the huge number of people the un says are now in danger, almost two million are in nigeria,

nearly five million in south sudan, nearly three million in somalia, and more than 14 million in yemen. the un is predicting that, without serious help, 1.4 million people could die before the end of the year unless more aid money is found. they're calling for £3.6 billion to tackle this crisis. aid agencies on the ground say at the moment they do not have enough money to deal with the rising demand for help. a child who suffers from severe, acute malnutrition, unless they are treated, there is a high likelihood that they will die. if they are treated, then they can recover completely, and the cost of that treatment can be as little as $80. apart from conflict, another major cause of the crisis is drought. this is somalia, which has been particularly hit hard. in this hospital in the capital, mogadishu, almost 50 children have died in two months, most from dehydration.

with the lives of so many children like these now at risk, the un believes the global response must be quick. richard galpin, bbc news. stay with us on bbc news, still to come: some flipping good news from florida. the sea turtle returning to the ocean after an unhappy accident. the number of dead and wounded defied belief. this the worst terrorist atrocity on european soil in modern times. in less than 2a hours the soviet union lost an elderly sick leader and replaced him

with that story now. with me is aylina kilic, a journalist following turkish issues here in london. thank you very much indeed for coming in. the situation seems to be developing all the time now. the dutch police are on horseback and riot police called out. what is president erdogan trying to achieve with what he is doing? is he toward aiding the ministers' visits? well, with the ministers' visits, what he wishes to do is he wants to make sure that the election campaign which is right now on sure that the election campaign which is - right now on the which is ongoing right now on the proposed referendum system to be yes vote by the majority of the turkish public. so what he wants to do now is he wants to gain the support of the turkish diaspora, which is why

he is also leading the election campaign into europe especially. what were the scenes like this, though? we have had these pictures coming in on the last few minutes. what will the scenes like this be doing domestically, do you think? well, domestically, these scenes will actually help the situation in erdogan‘s hands, because he has been campaigning from long time for the presidential system. and, as you may know, turkey has been faced with terror attacks in the last few months, and he has always use this, and especially the july 15 coup attempt, which was the reason why he is saying that the referendum system should be resolved with a yes vote. so these scenes will strengthen him, giving? yes, definitely strengthen him, but at the same time it is also

polarising and dividing the turkish society. because what they are doing is what turkish officials are saying is what turkish officials are saying is that those who are saying no art terrorists, and are siding with a terrorists, and are siding with a terrorist organisation. as you know, the people, the soldiers who carried out the july 15 coup attempt, the people, the soldiers who carried out thejuly 15 coup attempt, has been branded as a terrorist organisation by turkey. so they have been using this as a way to say that people should say yes in the campaign. ok, do you think we are now likely to see more protest? is the strength of feeling, do you think, with so many turks living in other eu countries, that there is a strength of feeling that some of these protests might now spread? definitely, yes, because it plays with the nation's voters. the nationalist leader of turkey, the party leader, he has called out to turks who are nationalists to go out on the streets in europe and protest

about what especially happened in rotterdam. so i think this will especially play out into their position, because what they want to do is cause the public to have the anger against this. because obviously what has happened in rotterdam is a situation where the turkish minister has been turned away. and although this is actually away. and although this is actually a breach of the turkish constitution itself, because the turkish constitution says that no political campaign can be carried out in a foreign country for propaganda purposes. now, there is going to be lots of people who look at the language that president erdogan has used. this idea of calling them remnant nazis, fascists, and using that particularly in the netherlands, is very, very controversial. yes, definitely. but it definitely really does help the us voters to have a huge reason to

campaign more for what they want to respond in the campaign. but do you think he has deliberately chosen those words and then use them, or do you think when he gets up and gives a speech he is not quite sure what he is going to say, and hejust happened to pluck those words out?|j think you definitely knew he was going to use those words, because obviously his base, his voters, ak party voters, they are obviously coming from this space, so this will affect them, so he knows what to say, definitely. thank you very much indeed for your expertise. more than 30 years ago, the brazilian city of cubatao became known as the valley of death because of its severe air pollution. photos emerged of the effect of that pollution on newborn babies. three decades on, the authorities are trying to clean up the air, as camilla costa reports from cubatao, in the south—east of brazil.

36 years ago, this place was known as the valley of death, a city where the levels of air pollution are so high that children were being born with malformations. cubatao, which might be the world's most polluted city... might be the world's most polluted city. . . these might be the world's most polluted city... these pictures from 1981 show just how bad city... these pictures from 1981 showjust how bad it was. this man remembers what it was like to live so close to a complex of over 20 industries. translation: once i saw a child here running and screaming. it is the rain that bites, he said. ididn't it is the rain that bites, he said. i didn't know what that meant, but later i realised it was the acid rain, which burned the skin. when brazil came down to set up its first industrial park in the 1950s, this seemed like the perfect place for it, as it is very close to the largest port in latin america. but

this mountain range behind me traps the air, the clouds and the polluta nts the air, the clouds and the pollutants inside, effectively turning the city into a greenhouse. change finally came with real—time monitoring of the air, and filters on the chimneys of factories. translation: brazil was one of the last to adopt simple solutions that other countries already used, like filters. once we had an agency to oversee the industries, the quality of the air improved. industrial activity are still responsible for high levels of pollution in cubatao. now an environmental engineer and a teacher, cleiton says the city has to do more. your students barely know about what happened in the 19805, know about what happened in the 1980s, he says, but he believes that keeping the past alive is the best way to prevent future mistakes. —— his students. the indian prime minister, narendra modi, and his bjp party are celebrating after a landslide victory in elections in uttar pradesh.

the state is the country's most populated and influential. it is a decisive victory for mr modi, especially after his blunder over withdrawing high—value banknotes. from delhi, sanjoy majumder reports. the man who is on everyone's lips. modi, modi, modi! ..and whose control over india is now absolute. prime minister narendra modi has just delivered a stunning victory for his party in the country's political heartland, uttar pradesh, and at the bjp headquarters, it is time to celebrate. the party now controls more than half of india's state governments, leaving the opposition trailing in the dust. translation: this is a historic win. the people of uttar pradesh have put their faith in prime minister narendra modi. translation: his hard work speaks for itself. he's always working for our country's development. how could you not trust him? these mightjust be local elections,

but there is a reason why the bjp and its supporters are so pleased with this victory. it means that narendra modi's grip over india has consolidated after this victory. it means that he has very few challengers looking ahead to the next general elections in 2019. and, most of all, it means that he can take risky political decisions and win. late last year, indians faced massive cash shortages after mr modi's shock decision to ban high—denomination banknotes. it effectively sucked out more than 80% of the total currency in circulation, creating hardship for many, especially in rural areas. but, as these election results have shown, it has had little impact on the fortunes of india's prime minister. sanjoy majumder, bbc news, delhi. a giant green sea turtle has been returned to the sea off

the florida keys, a month after becoming tangled in a crab trap. it is a triumph for workers at a turtle hospital who have worked hard to get the creature, who is at least 50 years old, back in the wild. janey mitchell has more. joy, as jolly the female turtle is released back to the wild off the city of marathon, florida. jolly was named after the wildlife officers who helped rescue her from multiple crab trap lines last month. weighing in at 150 kg, she made a quick recovery from the partial amputation of her right rear flipper. her release is timely. the nesting season in florida keys starts in april. so she, being a mature female, she can get out there in time to date and hopefully lay some eggs. breeding is all the more crucial in view of the green sea turtles'

listing as a threatened species in the atlantic ocean. it's really important to get a turtle this mature back out into the wild. they're sexually mature, which means they're reproductive, and sea turtles aren't reproductive until they're 20 or 25 years old. jolly is probably 50—plus years old, so that's when we want to make sure she gets out, so she keeps making baby turtles. jolly could live to 100 or more, so well worth shelling out for her treatment and care. janey mitchell, bbc news. a reminder of our top story. in the past hour, dutch riot police on horseback and using water cannon have broken up a demonstration by supporters of the turkish president outside the turkish consulate building in rotterdam. it comes after the dutch government prevented two turkish ministers from addressing a rally there. the president called the dutch cabinet

nazi remnants. hello there. saturday brought northern ireland its warmest day of the year so far. we will see some sunshine but the warmth will not be repeated today. this was the saturday evening sunset and 16 was the temperature that we reached, about 61 fahrenheit. there was 18 in the sunshine in the south and the east, and it was on the whole a fairly decent day for most. however we did have that weather front around. the rain has been pepping up with heavy bursts of rain in the south and the odd rumble of thunder off the south coast. so we do have notjust one but two weather fronts to contend with for sunday, an awful lot of cloud, misty low cloud, hill and coastalfog, so for most, sunday is going to get off to a mild start. this rain in the east obviously bringing a different day for eastern england, and damp weather in northern ireland

in the morning, moving soon into wales and the south—west of scotland. remember, all the time it is going to be a gray and misty start. so a lot of low cloud around the hills and coastal fog as well. behind this first weather front and ahead of the next one we may well have some brighter weather through the east of wales, midlands, into parts of northern england and central scotland. but still quite murky near the east coast of scotland compared with saturday, and that rain band getting into the west. now, all the time, the rain in the east will be fizzling out. it looks as if the rain further west as it heads its way in will tend to become more showery as well. there will therefore be a lot of cloud around and more limited brightness. it looks lovely for northern ireland in the afternoon, western fringes of the uk. and that means we will see some sunshine but it will not feel as warm as it did during the day on saturday. temperatures only 12—14 degrees. and then through the night, as the skies clear further, we are in for

a chillier night. we could have a frost, a light frost as we head into monday morning. perhaps the far south and east still quite cloudy, so still escaping, but with high pressure building in for the start of the week, it means that the weather is settling down. so monday looks like a decently dry day, with some springlike sunshine, just not the springlike temperatures we saw through the first half of the weekend. still, 1a or 15 with sunshine is pleasant enough. but that weak weather front is starting to invade from the north—west. the breeze is increasing, so tuesday brings more cloud and not much rain. it hangs around into wednesday before the pressure tries to build back in again, and the weather fronts mostly pester northern and western parts through the coming week. you can see risk of cloud in the south on tuesday. still a lot of cloud into wednesday. as ever, there is more detail on the website. bye bye. the latest headlines from bbc news. i'm gavin grey. riot police in the netherlands have fired water canon at turkish demonstrators in rotterdam after the dutch government stopped
