welcome to bbc news, i'm reged ahmad. our top stories: president trump announces major new sanctions on iran in a bid to stop it obtaining nuclear weapons. the fact is we are not going to have a run have a nuclear weapon. and when they'd agree to that they are going to have a wealthy country, they are going to be so happy and i am going to be their best friend. targeting europe's biggest polluters — climate change protesters storm a german coal mine to campaign against fossilfuels. and, 30 years after the velvet revolution, the czech repulic braces for another mass demonstration to demand the prime minister's resignation.

president trump says he plans to impose even more sanctions on iran, as tensions escalate between the two countries. just days ago, mr trump called off an airstrike on iran at the last minute — in response to the shooting down of an american drone. last week, the us blamed iran for attacking two oil tankers in the gulf of oman, which tehran has strenuously denied. from washington, chris buckler reports. for the moment, donald trump is choosing sanctions as his weapon, not force. but the us military remains primed and ready in the gulf, and while the president abandoned strikes on iranian targets on thursday, the countries still appear to be on a collision course, unless something changes. if the leadership of iran behaves badly, then it's going to be a very,

very bad day for them. but hopefully, they are smart and hopefully they really care for their people, not themselves. and hopefully, we can get iran back onto an economic track that's fantastic. washington is putting further sanctions in place in an attempt to prevent iran developing nuclear weapons. tehran has already warned it is about to breach limits on the amount of enriched uranium it can stockpile, putting the future of the iran nuclear deal in doubt. by threatening the accord, they are trying to get america's allies to put pressure on president trump to relax the sanctions that are causing real pain for people in iran. translation: the economic situation is changing every day. sanctions and welfare are getting worse. this is because the two governments, iran and the us, are escalating tensions.

after attacks on tankers and the downing of an american drone, the strait of hormuz is not only one of the world's most important trading routes, it is the centre of international tensions. chris buckler, bbc news, washington. hundreds of climate change protesters have stormed an open cast coal mine in western germany, during a weekend of campaigning against fossilfuels. they ran through a police cordon after gathering at the garzweiler mine early on saturday. local residents worried about plans to expand the site were joined by teenage activists. gareth barlow has more. activist pour in where coal pours out. activists stormed the mind that produces 50 million tons of coal a year, others campout on train tracks, which they first occupied on friday, to prevent cole from leaving the site. translation: we want to

block the infrastructure because we wa nt block the infrastructure because we want germany to phase out of the brown coal conversion, which is the most harmful for the environment. police clashed with the protesters, and the mine owners defended the operation. translation: these are violations of the law. that is unacceptable. these demonstrations are unnecessary, because we do not block the phasing out of coal. something we are being accused of. since 2012 we have decreased our co2 emissions by 50 million tons, that is 3.4%. recent opinion emissions by 50 million tons, that is 3.496. recent opinion polls show that climate change tops a number of concerns in germany. angela merkel and her party have vowed to make it carbon neutral by 2050, but activists say that is not enough. the czech capital, prague,

is bracing for the biggest demonstration since the 1989 overthrow of communism, as people gather to protest against the prime minister, andrej babis. the billionaire businessman is facing a criminal investigation over alleged fraud, and is also the subject of an eu conflict of interest investigation. mr babis has dismissed all the allegations as baseless and politically motivated. rob cameron sent this report from prague. 30 years ago, people power brought down an entire system as mass demonstrations proved too much for the communist regime. three decades on, these streets will soon be full once again as people protest against prime minister andre babis. organisers are holding their rally at the same location, this time not against a dictatorship but a

democratically elected government. against a dictatorship but a democratically elected governmentlj think democratically elected government.” think the most important part of democracy ‘s elections, and we support that. it doesn't mean that once you elect somebody you must just stay silent and let politicians do anything. politicians cannot break some important rules, which is 110w break some important rules, which is now happening in the czech republic. many people share that view. andrej babis might have one successive elections and still tops opinion polls, but there is something greater at stake here — the sense that the hard—won freedoms of the velvet revolution are being undermined. i think that he is very focused on profit, and i think he is also very focused on himself, and i think he proves it in the last few yea rs. think he proves it in the last few years. i think it is dangerous if things stay how they are now. this

prime minister, babis, he isjust trying to take over control of the whole country, and it is going to be dangerous in the future. mr babis says he will never resign over the fraud allegations, and for now he has the support of cabinet colleagues. right now of course i am sorry that these protesters are going against the government, because i think that the government works pretty well, that we are doing a good job in general. of course, i know that there are some protesters, ican know that there are some protesters, i can see them and feel that right 110w i can see them and feel that right now the situation is a bit nervous, but i take it as part of democracy. andrej babis and the czech government have tried to put a brave face on these protests, but with separate investigations by both the czech police and the eu, how much

more pressure can one man take? let's get some of the day's other news. three suspected al—sha bab militants have been killed after they attacked a police camp in kenya, close to the border with somalia. the al-qaeda—linked group has vowed retribution for the country's involvement with amisom, a 20,000—strong african union force helping to support the government in somalia. kim jong—un says he's received a personal letter from president trump. state media in north korea reported that mr kim saluted the extraordinary courage of the american president, although it was not disclosed when or how the letter was delivered. earlier this month, the us president said a beautiful letter had been sent to him by north korea's leader. polling stations have officially closed in mauritania, a country marking its first democratic transfer of power since independence from france in 1960. president mohamed walid abdel aziz seized power in a coup in 2008, but he's agreed to step down and abide by a two—term limit of office. six candidates are

running to replace him. anti—russian protesters in georgia have held a third day of demonstrations. thousands of people gathered in front of the parliament building in tbilisi, calling russia an occupier state. in response to the protests, russia has announced a ban on flights to and from georgia citing security concerns. the two remaining contenders in the race to become the next prime minister, boris johnson and jeremy hunt, have been making their pitches in front of conservative party members. boris johnson was the first to speak but he avoided answering questions about why the police were called to the flat he shares with his partner in the early hours of friday morning. here's our political correspondent, vicky young. have you ruined your chances of becoming prime minister, mrjohnson? mrjohnson, why were police outside your house last night? he's been accused of hiding

from scrutiny, avoiding detailed answers about his policies on brexit and tax. we meet in dark days for our party... today, the questions were more personal. as borisjohnson faced hundreds of conservative party members and was asked why police had been called to his flat in the early hours of friday morning. i don't think they want to hear about that kind of thing, unless i... applause. police were called to the flat borisjohnson shares with his girlfriend, carrie symonds, after neighbours reported hearing an angry row and were concerned about her welfare. a neighbour passed on a recording to the guardian newspaper. it is reported a woman could be heard screaming and saying, "get off", and "get out of my flat". the metropolitan police told the bbc there was no cause for police action. so what about questions of character? would mrjohnson answer that? does a person's private life... booing.

don't boo, no, no, don't boo the great man. don't boo him. when he answers this question, i will move on. no, no, no. does a person's private life have any bearing on their ability to discharge the office of prime minister? well, no... i, look, i've tried to give my answer pretty exhaustively. on brexit, he said he was determined to take the uk out of the eu by october 31st. what i said was that leaving on october 31st was, my words were "eminently feasible", which was taken to mean that i wasn't100% determined to do it. "eminently feasible" means it is not only that we are going to do it but it's possible. borisjohnson is the favourite in this race. some think he already has a foot on the steps of number 10. but leadership contests are unpredictable. he could face more uncomfortable questions, as he has today. some in this room do think he's a risky choice, but given the dire state of the conservative party, they might just think

he is a risk worth taking. up next, the foreign secretary, jeremy hunt. he campaigned to remain during the referendum. now he wants to lead a pro—brexit party. so could he be trusted to deliver? if we got to the 31st of october and the eu have not shown any willingness to negotiate a better deal that can get through the house of commons, that's not going to trap us in the customs union, then myjudgment is that, weighing those difficult options up, the political risk of no brexit is far worse than the economic risk of no deal. and what about his character? did he have the charisma and steel to be a prime minister? some people would say, "he's too nice". i think it's possible to be very polite and very tough. and i think my track record shows, you know, some very difficult industrial disputes that i had at the department of health. the advantage of the politeness is that people will talk to you.

but by golly, i hope they don't underestimate you, because i'm going to get that deal. what did you make of it? i thought boris was absolutely fantastic. he was electric. the room came alive as soon as boris entered the room and he spoke, it was absolutely brilliant. jeremy surprised me, i have to say. he came over much better than i thought he would. and it's food for thought. what did you think about questions about borisjohnson's personal life? i mean, it was inevitable, given the timing, that they would be asked, and probably, probably inevitable that he would choose not to answer. there will be 15 more of these hustings before conservative members choose our next prime minister. plenty of time for more questions. vicki young, bbc news, birmingham. there are a lot more details on our website about the leadership contest. you can get a comparison of

the two men, and also their brexit policies and some details of the timeline of the vote. more details on our website. two typhoon fighter aircraft were scrambled tonight to escort a plane back to a london airport after reports of a disruptive passenger on board. thejet2 flight had been travelling to dalaman in turkey when it was redirected back to stansted. a 25—year—old woman has been arrested. manchester airport has said an it failure prevented many passengers from checking in at all three of its terminals for several hours yesterday. long queues built up, with some passengers describing chaotic scenes. the airport says the problems have now been fixed. this is bbc news, the headlines: president trump has announced

"major" new sanctions on iran. he says it's to stop the country obtaining nuclear weapons. climate change protesters have stormed a german coal mine as part a week—long campaign against fossilfuels. a foreign office minister is going to iran later today to call for an "urgent de—escalation" of tensions in the region. the situation also has a bearing on the case of nazanin zaghari—ratcliffe, a british—iranian woman imprisoned in iran on charges of alleged spying. both she and her husband are on hunger strike in protest over her treatment. richard ratcliffe is camped outside the iranian embassy here in london. certainly increased engines make it difficult for us, certainly watching the news closely we owe worried if things get too far. so i'm worried the minister has died is a worry for the minister has died is a worry for the deescalation of tensions —— minister has started to lobby, so

she still is in the general ward with women with the other women looking after her and checking she is ok. the prison clinic is beginning to worry and keeps checking on her. they keep waiting to see what response there is from iran in authorities, there wasn't one today. day eight has been tough, i'm getting tired and slower of thinking. not hungry, oddly, buti thinking. not hungry, oddly, buti think it's a gradual deterioration of being able to operate. so for i'm able to give strong —— so far. there's growing evidence that an increasing number of businesses and organisations are paying out millions to hackers in secret against the advice of law enforcement agencies. so—called ‘ra nsomware' attacks, although in decline overall, appear to be becoming more targeted, with the computer systems

of governments, institutions and multi—national corporations being hijacked until a fee is paid. cybersecurity reporterjoe tidy has been to visit one norwegian company still recovering after thousands of their computers were taken offline by hackers. nestled away in the norwegian forest, this aluminium plant had no idea it was being targeted by hackers. but when it was hit, it was just one of 170 sites brought to a standstill by a catastrophic cyberattack. computer systems went down everywhere. 35,000 employees forced use pen and paper. five weeks on, they are still recovering. this is another one of the computers that went down. so that was all gone? all gone. for days, olaf managed to keep his plant going manually. he relied on the skills of long—since retired workers and long—since forgotten paperwork. at the company's global headquarters in oslo,

they are still rebuilding their systems. as we were being attacked, we had to shut down the entire network. 40 countries, 22,000 pcs. we are still very much recovering. we don't trust anything. the hackers' ransom note that appeared on computer screens was typical. for a large fee, probably hundreds of thousands, they would restore the compa ny‘s files. but hydro never tried to negotiate and refused to cave in to the cybercriminals. i think in general, it is a very bad idea to pay. it fuels an industry. it is probably financing other sorts of crime. but there are plenty of companies who are paying and keeping it secret. to understand the scale, we need to go to the us, where ra nsomwa re payments are an open secret. this group will divvy up 80% of the bitcoin. codeware is one of a handful of companies that have started helping victims navigate the murky

world of cyber extortion. we always have at least half a dozen to a dozen cases. are these big companies? some of them are, yeah, public companies and name brands. industry analysis suggests that overall, ransomware attack numbers are in decline. hackers are increasingly going after bigger targets and demanding more money. we recognise that when a company needs to pay, and it's a large number, then that's what needs to happen and that could be seven figures. how do you feel when you pay seven figures? not good. it is not a good outcome. everybody recognises it's not a good outcome, but you are dealing with the life and death of the company. there's no doubt it is a major dilemma and it's something authorities are trying to take control of without legislation. continuing to pay ransom perpetuates the crime. it actually makes the criminals — encourages them to commit further crimes and again, the whole idea, if you pay, you're actually fuelling organised crime on a global basis. but looking at the damage caused

at hydro, it is obvious why the easy way out is attractive. full recovery is still months away. the repair bill currently stands at well over £40 million. joe tidy, bbc news. events have been held across the uk to mark the first national windrush day — named after a ship that brought hundreds of caribbean migrants to help rebuild postwar britain. the government made the announcement last year after it emerged that some of the windrush generation and theirfamilies had been wrongly accused of living in britain illegally. adina campbell went to meet some of those taking part. five, six, seven, eight. one last practice for these schoolchildren in north london. for weeks they've been preparing performances for a special audience. some of the residents in this care home belong to the windrush generation and have been sharing their stories with their younger guests. hi, my name is kayla. where do you come from?

i'm fromjamaica. do you remember the year when you came? yeah, 1959. what was your first day like in the uk? it was all right. when i came, i settled down. newsreader: the empire windrush brings 500 jamaicans. the empire windrush docked at tilbury port in essex back in 1948. hundreds of passengers from the caribbean who were invited over after the second world war left their families are to start a new life in the uk. taking upjobs in the nhs, armed forces and other public services. some of these experiences are reflected in the group performances at the care home. half a million pounds of government funding has been made available for community events all over the uk, to celebrate members of the windrush generation theirfamilies. # i don't need nobody #.

it is hoped these extraordinary stories will help us remember their valuable contribution. # all i need is you #. adina campbell, bbc news. 0h, oh, ilike oh, i like it. you like it? it's hoped that blood from patients with mental health problems like schizophrenia could help develop new drugs to combat their illnesses. the medicines used currently don't help everyone with the condition, so cambridge university hope the method they've developed could lead to a new drugs breakthrough. here's our science correspondent, richard westcott. there's a growing realisation that mental health problems aren'tjust in our brain. that they can affect many different parts of our body, including our blood. so, effectively, you have taken the blood from people with schizophrenia and people without schizophrenia,

and you can see the differences in their blood? yeah, absolutely. so it actually turns out the cells from patients with schizophrenia utilise calcium in a slightly different way. the calcium is used to communicate within the cell, and the cells from patients with schizophrenia are communicating in a different way. the cambridge team is now using that difference to try out new medicines. if a drug fixes the problem in the blood, it could also help make the patient feel better. until now, people with schizophrenia have used trial and error to find a drug that works for them. the whole process can take years, if it works at all. but by testing different drug treatments on something as readily available as their blood, this team hopes to speed up the process and find new medicines. the main intention is really to identify drugs which are currently already exist and are already used in patients for other diseases,

like heart disease like inflammation, et cetera. and also help patients with schizophrenia. it's extremely hard to take brain cells from living patients, but it's simple and safe to take and test their blood. and all you need to see what is going on inside the cells is some bright lights. the best way to analyse the blood is to put fluorescent dye on it and shine a laser on it, and that shows you exactly what is going on inside. this technique could potentially work for a number of mental illnesses. we ourselves have looked at bipolar and autism spectrum disorder, and we found abnormalities in the blood for all of those. one in five of us will have mental illness in our lives. testing new medicines on our blood should fast—track the process to find new treatments.
