president trump has withdrawn the united states from the international deal that limits iran's nuclear ambitions, ignoring the wishes of his european allies. they have expressed regret and say they'll try to save it. israel and saudi arabia have praised mr trump's decision. the us is also reinstating the highest level of sanctions on iran. nick bryant reports from washington. with a flourish of his presidential pen, donald trump has inked into history one of the most muscular pledges from his "america first" campaign, one that delivers a potentially fatal blow to the signature foreign policy achievement of his predecessor, barack obama, one that could put the united states on a collision course with iran. the fact is, this was a horrible, one—sided deal, that should have never, ever been made.

it didn't bring calm, it didn't bring peace, and it never will. therefore, i am announcing today that the united states will withdraw from the iran nuclear deal. in one of his toughest speeches yet, he said he would reimpose the highest level of economic sanctions against tehran. america will not be held hostage to nuclear blackmail. we will not allow american cities to be threatened with destruction, and we will not allow a regime that chants "death to america" to gain access to the most deadly weapons on earth. today's action sends a critical message. the united states no longer makes empty threats. when i make promises, i keep them. the nuclear deal was struck in 2015 between iran and six world powers, including the us, uk and russia.

iran agreed to limit its controversial nuclear energy programme, which international powers feared could lead to the development of a nuclear weapon. in return, stringent economic sanctions were lifted, enabling iran to sell more oil to other countries and trade more efficiently. iran's president, hassan rouhani, deliberate an almost instantaneous response, saying his country was preparing to restart uranium enrichment, key for making both nuclear energy and weapons. translation: i have ordered the atomic energy organisation of iran to be ready to start the enrichment of uranium at industrial levels. we will wait a few weeks and speak with our allies. all depends on our national interests. european architects of the deal, present at its creation three years ago, tonight gave a very grim—faced response.

the european union is determined to act in accordance with its security interests, and to protect its economic investments. the nuclear deal with iran is the culmination of 12 years of diplomacy. it belongs to the entire international community. it has been working, and it is delivering on its goal, which is guaranteeing that iran doesn't develop nuclear weapons. but praise from america's closest middle east ally. israel thanks president trump for his courageous leadership, his commitment to confront the terrorist regime in tehran, and his commitment to ensure that iran never gets nuclear weapons, not today, not in a decade, not ever. from barack obama tonight, a rare public rebuke of his successor. he called mr trump's decision misguided, and a serious mistake. this will make america much safer.

but donald trump is unapologetic. for him it is promise made, promise kept. in tehran, there was an immediate and angry reaction from president hassan rouhani. he said iran would respect the deal for now, and consult with the other world powers who signed it. but he ordered officials to get ready to start enriching uranium again "at industrial levels." this from our chief international correspondent lyse doucet. tonight's news in tehran, state tv‘s most important headline in years. trump withdraws from the nuclear deal. moments later, president rouhani's turn. flanked by men who spent years negotiating this landmark accord. translation: from this moment on, the nuclear agreement is between iran and five other countries. in these circumstances, we have to wait and see out the five other countries will react.

iran's next step depends on europe. nearly three years ago iranians celebrated the end of sanctions, the start of a new relationship with the west. it did not last long. today the iranian real fell almost record lows against the dollar. "we expected this to happen," this man says on state tv. "in or out of the deal, what difference does it make?" even hard—liners who opposed the deal might rally around the president, for now. the united states does not understand he is bringing together political opponent in the iranian system and he is bringing them together on the wrong side of engagement and he's going to promote their ideas, hardline ideas of resistance, and that is going to be provocation will and also detrimental for iran's future domestic politics. the other impact will be in the region. there is one line in this deal

which speaks of hope that it will positively contribute to peace and security in the region. but, as the deal unravels, the fear is regional tensions will now escalate, especially with iran's growing influence everywhere from iraq through syria to lebanon along israel's border. and tonight that tension is mounting. israel is braced for possible iranian retaliation after recent air strikes in syria a conflict which intensifies just as a deal meant to prevent up war seems be falling apart. live now to washington dc and alireza nader, an expert on iran. welcome. thank you for your time. as you know, the stated reason from the trump administration for this is to stop iran acquiring nuclear weapons.

this instruction to start enriching uranium again suggests it could have the opposite effect. well, i think the opposite effect. well, i think the iranian regime is going to suffer severe —— suffer a severe blow. so even if they threaten to increase in richmond, i did is playing a relatively big hand, here. in what sense? —— to increase in richmond. the iranian economy is going into crisis. —— enrichment. the country has been going through months of unrest. the us withdrawal puts a lot of pressure on the regime. what impact it isn't likely to have on the rest of the country, do you think? i think it can cause

additional unrest. since december there has been demonstrations and strikes every day. i think the population in general is very angry with the regime, and that includes president hassan rouhani. i think a lot of people make this distinction between moderates and hardliners that no longer really applies to iran because iranians are tired of the islamic republic in one solutions. and so far only failure has been delivered by president hassan rouhani. what is the plan to start in reaching again tell you?” think it is the best leveraged they have. —— enriching. they can increase to 20%, and increased nuclear weapons capability, but that will only isolate the further and make the european union rethink its

financial and trade ties with iran. so it is a risky move for the regime to threaten to ramp up its nuclear programme. can the other world powers, the other signatories to the deal, keep it alive, do you think? yes, i think they can. but it will just be the european union and russia and china and iran. i think the us has majorfinancial average. if the us sanctions, at any company thatis if the us sanctions, at any company that is going to be very unwilling to continue trade ties with iran—so evenif to continue trade ties with iran—so even if iran stays in with other players, what really matters is us action, and the us has decided to withdraw and this will have a tremendously negative financial consequence for the uranium regime. what do you think the gameplan is here? there has been a loss to talk

about war with iran. you wonder at this is the long—term strategy, to crush them militarily, encourage israel to do so. crush them militarily, encourage israelto do so. i don't crush them militarily, encourage israel to do so. i don't think war is in the plan. i think that what the trump administration can do and will do is to put more pressure on the regime and start talking to the iranian opposition. there is no need for military action. i think the us has many other options to pressure the regime. alireza nader, thank you very much. and there is a lot of other news to cover. some of the other news to cover. some of the other stories making the news right now: malaysians are voting, following one of the most hotly contested general election campaigns in the country's history. an opposition coalition, now headed by the 92—year—old former prime minister mahathir mohamad, is hoping to win power for the first time since independence

61 years ago. critics are worried the election will not be free and fair. the democratic republic of congo has declared a new outbreak of ebola in the north—west of the country. tests have confirmed two deaths from the disease so far, but other cases are suspected. the world health organisation said a team of experts was on its way to the affected area. the man who led weeks of protests in armenia has addressed his supporters in the capital, yerevan, following his election as prime minister. nikol pashinyan promised that human rights would be protected, and that corruption and election—rigging would end. the film director, roman polanski, is threatening to sue the oscars academy following its decision to expel him for misconduct. polanski fled the us in 1978 after pleading guilty to unlawful sex with a teenager. his lawyer says the academy‘s actions are in breach of its own procedures and california law. it's emerged in the past few hours that america's top diplomat is making his second visit to north korea in less than six weeks. secretary of state mike pompeo has arrived in pyongyang for talks on the release of three american prisoners and to prepare for the proposed summit with president trump. north korea's leader has just been

in china for talks with president xi. china is keen to maintain its influence — as john sudworth reports from dandong, on the chinese border with north korea. as the two men took their amiable stroll by the sea, it was hard to believe that one was, just a few months ago, an international pariah with whom even china was said to be losing patience. now, he is the man of the moment. the chinese president signalled his approval. dialogue with america, he said, can bring peace. in the city of dandong, up the coast from where the leaders are meeting, investors clutching property portfolios are hoping that with peace comes something else — prosperity. translation: property prices rose a lot this year. they doubled. they've gone up because of kim jong—un. only a narrow stretch of water separates the city from north korea, and the contrast between the two

banks could not be more stark. this bridge ends in a field, because north korea has not yet built the connecting road. it is a pristine, gleaming highway, and it is proof of the huge economic potential if the impoverished country at the other end of it ever were to open up. but this unfinished bridge is proof of something else, too — that time and again, just as the world has sensed change, north korea has chosen isolation over reform. chinese homes along the border have quite literally been shaken by the nuclear tests. there are plenty here who doubt whether north korea, having tried so hard

to get its weapons, will ever give them up. but one chinese couple, in their new home overlooking the new bridge, insist that this time the difference might be kim jong—un himself. translation: he is a young leader. he has been been abroad. i think he wants to develop north korea, and improve its economy, so i think there is hope. but chinese reports suggest mr kim won't accept unilateral disarmament. beyond the goodwill, it is a potential stumbling block, and a reminder that it is only a few short steps back to the brink. john sudworth, bbc news, dandong. stay with us on bbc news. still to come: champions of conservation — we meet the women protecting zimba bwe's wildlife. i, nelson rolihlahla mandela,

the latest headlines: donald trump pulls the united states out of the iran nuclear deal, calling it defective to its core. the eu says it's determined to preserve the agreement but iran has insisted it could start enriching uranium without limitations. scientists in indonesia have launched the largest ever study into the impact of tiny plastic particles on human health. they're investigating the presence of microplastics in seafood — while also tracking the diets of two—thousand people. our science editor, david shukman has been to semarang on the north coast of java in indonesia, one of the countries worst hit by plastic pollution. a journey through the mangrove swamps on the coast of indonesia.

indonesia sends huge volumes of plastic into the ocean. only china releases more. there's so much, itjams our boat's propeller. the problem is that when plastic flows down the rivers and reaches the ocean, it doesn't just disappear. what happens is that the plastic breaks down into ever smaller fragments, what are called microplastics. so even though there is an effort to clear up, the legacy of plastic continues. so we head to the local fish farms, because research in britain shows that microplastics can get into seafood. ijoin scientist inneke hantoro as she investigates a key question — whether eating plastic is harmful. we eat the fish every day and we don't want to get plastic into our body due

to eating the fish. so we want to see whether it is safe enough to eat the fish. a microscope shows a plastic fragment found in seafood. it's a couple of millimetres long. scientists want to establish a safe level for microplastics. in case we later find out that they are harmful. it is not a problem that many here have heard of. in a local market, i ask this fish seller if she realises that her fish might contain microplastics. "it's impossible," she says, "because the seafood is fresh." "my fish are clean." but as she is talking, plastic waste is being stuffed into bins right behind her. up the road, this factory uses plastic in all its packaging. a lot of it is bound to end up in the rivers and the oceans. but the boss here says he wants to prevent that. so he is sponsoring classes in how to make what are called eco—bricks. people are taught to take old bottles and cram all kinds

of plastic waste inside them. when the bottles are glued together they can make furniture or even walls. i think first up the best we can do so far is build a better solution for the plastic. this is the thing so we can stop the plastic from going into our environment. at least to trap it so it doesn't cause pollution? exactly. ultimately, plastic is going to keep accumulating and entering the ocean unless two key things happen. setting up a proper system for handling waste but also seeing a complete change of attitude amongst people, businesses and the authorities. and even if the larger pieces are cleared up, the microplastics will drift around for decades. david shukman, bbc news, indonesia. another passenger bus caught fire and exploded in the heart of rome, sending a plume of black smoke over the city centre. the driver and passengers all managed to escape before the flames took hold — as the bus stopped near the trevi

fountain. it's the latest in a number of similar incidents, raising yet more questions about the state of public transport in the italian capital. lebo diseko has more. the number 63 bus in the centre of rome engulfed in a ball claims that there is no play suspected here. instead, the finger is being pointed at the local transport company. at least nine of its buses have caught by this year. last year, there were 22. drivers unions say its vehicles are properly maintained. they have warned of issues before. the company blames an ageing fleet, saying it has put safety measures in place which have cut the number of incidents. many in rome say the mayor is in fault for not fulfilling

a promise to tackle the city's transport problems. so far, there has been no one seriously hurt in any of these incidents but the theories of authorities don't get to theories of authorities don't get to the root of the problems, that may soon change lebo diseko, bbc news. facebook has banned foreign advertising linked to ireland's referendum on liberalising its abortion laws. critics had warned that campaigns by well—funded us groups could swing the vote. the company said it wanted to protect elections and referendums from undue influence. there's a new weapon in zimbabwe in the fight against poaching — a highly—trained group of women determined to take on the criminals. poaching is threatening zimba bwe's wildlife — as well as other countries in east and southern africa. so could these women be the answer? shingai nyoka travelled to the north of the country to find out what happens when women take the lead in conservation. for decades, this was a man's job. physically gruelling foot patrols, tracking groups of poachers armed

and ready to kill. it's dangerous work. this area was once used for trophy hunting. bad management and poaching saw game numbers plummet. the women are working to revive it at protecting the 100 square mile reserve is a big ask. the privately funded project is managed by a former special forces soldier. more aggression this time! long—term solutions involve winning the hearts and minds of the community and the most effective way to do that is through the women. are you scared? totally. tonight, their training is being tested. following a tipoff, they are sweeping the village in door—to—door raids. these women are at the forefront of policing their own

communities and they just forefront of policing their own communities and theyjust arrested the fourth suspect in what they believe to be a commercial poaching syndicate. a major coup. they have netted a wanted ivory poacher. he is later jailed for netted a wanted ivory poacher. he is laterjailed for nine years for poisoning elephants with cyanide. the unit ‘s success hasn't gone unnoticed. so inspired by these women, the president's daughter signed up to be a volunteer ranger. conservation is going to play a huge role that zimbabwe is open for business. i think this is going to be key to seeing tourism being reignited in our nation. the project plans to roll—out more women only reserves around the country. it's become powerful idea, putting women in charge of zimbabwe's wildlife. to a former sector blighted by scandal and corruption. perhaps just

heading in from the west. we saw a weather system move through on tuesday. this one here, the leading edge of cooler air so things cool down for many. not quite into east anglia and the south—east of england, but in the day ahead, that process is complete. low pressure to the north—west of us and that's feeding in cooler, fresher conditions across all parts, and a bit of rain, as i mentioned, coming into the west. although most will start fine and dry for the morning, single—figure temperatures under clear skies but some in east and south—east england still around 10 or possibly 11 degrees. your eyes will be drawn to this weather system that will soon in the morning turn things wetter into northern ireland, into western scotland, the wind picking up as well, quite gusty into the western isles but it's really coming in very slowly so a lot of cloud increases ahead of that. many will be staying dry even on into the afternoon, particularly across eastern parts of the uk, and still some sunny spells into east anglia and south—east england, but temperatures here down significantly compared with recent days. that's how we end the afternoon. going into the evening,

some of us will be getting a wet evening rush—hour. some heavy bursts affecting western parts of scotland beginning to pull away from the western isles, patchy in nature to the east of scotland, not much into north—east england and clearing from northern ireland some will get the sun coming back before the end of the day, but more of wales and western england starting to get outbreaks of rain pushing into parts of the midlands too. much of eastern england will be dry and once this weather system crosses all parts, wednesday night into thursday morning, there isn't a huge amount of rain left on it. after the heat of the recent days if you want something on the garden, i think you're going to be disappointed. dry weather on thursday. there'll be a few showers developing, though, particularly into scotland, maybe the odd heavy one with a rumble of thunder. northern ireland and northern england, the rest of england and for much of wales, it is looking dry,

variable cloud and sunny spells. on the breezy side, if anything it's a little bit cooler still and some of us for the rest of the week towards in the north—west of the uk in particular will find temperatures below average for the time of year. another fine start for much of the uk on friday, but then we see another weather system gathering out to the west. the winds picking up ahead of that. while many on friday will stay dry, some will start to the outbreaks of rain. some uncertainty about the timing of this and the progression north—eastwards, so we will keep you updated, and temperatures still none too special. this is bbc news. the headlines: president trump has withdrawn the united states from the nuclear deal with iran. ignoring the pleas of some his closest allies, he called the agreement a horrible deal that should never have been done and he said he would impose the highest possible level of sanctions against tehran.

in response, the iranian president, hassan rouhani, ordered his officials to be ready to restart the enrichment of uranium at industrial levels. but he added that he would reach out to the other signatories of the deal to keep it in place. efforts are underway to strike a different nuclear deal — this time with north korea. after meeting china's president xi, kim jong—un's set for more talks with us secretary of state, mike pompeo, who's just arrived in pyongyang. the meeting paves the way for a summit with president trump in the coming weeks. now on bbc news it's time for a look at the day in parliament.
