position themselves washington has pulled out and impose sanctions on russia and china have said they want to keep the deal and they don't really mind the sanctions but europe also wants to keep the deal but at the same time it doesn't want to anger its allies in washington and that's a balancing act that is really getting difficult now so they might to have to take sides and they try to do so with instax that's a mechanism that would allow iran and europe to still trade even under the sanctions they promised to do that but they actually failed it has never really come into effect so now they have that deadline of sixty days to make it work and that's not a lot of time so the pressure is on europe right now so europe is between a rock and a hard place as it were now there is also a military dimension to this confrontation here you mentioned the aircraft carrier the u.s. aircraft carrier on its way to the region tell us more about this you know with a warship on the way there it's going well all the iranian military already is to

the strait of hormuz to the persian gulf and iran has long threatened to close that strayed off from was that's the place where all the international oil shipments have to go through that's obviously a way to put pressure on the west to block all the old shipments so with the u.s. soldiers going there there's a potential that they actually might directly face off and with a lack of diplomatic channels between those two countries right now that's really dangerous because under the obama administration the foreign ministers used to talk so they could talk about any sort of confrontation right now that's not the case so . that could take of the conflict to a whole new level and that's not just in the persian gulf because those two countries also could face off in syria for example in iraq or even in israel three said thank you so much for your insight steve w. correspondent there is a trucker. well donald trump is also facing problems

at home a committee in the democrat led house of representatives has voted to hold attorney general william barr in contempt of congress for refusing to hand over an unredacted version of the report by robert mueller investigative russian support for trump's twenty sixteen election campaign the head of the committee jerrold nadler said the us was now in a constitutional crisis as a result of the president's actions this was a. this was a very grave and momentous step that we were forced to take today to move a contempt citation against the attorney general of the united states we did not relish doing this but we have no choice attorney general barr having proved himself to be the person with turney to president trump rather the attorney general of the united states by misleading. the public as to the contents of the mother reports twice by not being truthful with congress. has shown himself to be

the personal attorney the united states rather than the attorney general and now we've talked for a long time about approaching a constitutional crisis we are now in it's we are now in a constitutional crisis. as you might expect white house sees things differently it says democratic lawmakers are the ones breaking the law by demanding a report with secret information the justice department which william barr heads had this to say. it is deeply regrettable that elected representatives of the american people have chosen to engage in such inappropriate political theatrics no one including chairman and his committee will force the department of justice to break the law all the w.'s all over sol it is following this story for us in washington he sent us this is meant of the standoff. it's another escalation in the

fight between congress and the executive branch of the us government a clear vote to hold attorney general william barr in contempt as he refuses to hand the full and unredacted moller report both sides are fighting fiercely u.s. president donald trump announced he would use his executive privilege to protect the formal report from congress what's ahead is likely to be a long courtroom battle but it's also about love within the democratic party the question is how much more do they want to fight as the american public is increasingly tired and the president could emerge the moral victor. w's all over saw it there well let's look at some other stories making headlines around the world today venezuelan security forces have arrested the vice president of the country's opposition controlled national assembly and some seen here on the left is the deputy of self-proclaimed president on. zambrano is the first opposition figure

to be arrested since the opposition's failed attempts to spark a military uprising last week. but two suspects being held over tuesday's school shooting in denver colorado in the u.s. have made separate appearances in court the prosecutors say they expect to file formal charges on friday one student was killed in the stooge shooting after he reportedly charged one of the attackers pinning him to a wall and thereby likely preventing further bloodshed. you're watching the news still to come on meet the activists who say germany is backsliding dangerously on its climate committee. now to south africa and vote counting is underway after what's being called the most closely contested election since the end of apartheid the ruling african national congress is tipped to retain power but it could face

a real challenge from a breakaway opposition party after its failure to improve living conditions in its quarter century in charge it's. voting day in south africa twenty five years after the first free elections many citizens are now fed up with the way the country is being run and during that entire time the african national congress has been in power people say south africa is mired in crime corruption and economic stagnation even president cyril ramaphosa who's from the a.n.c. admits to the problems corruption walked into the way the turn age got into the way . not focusing on your record into the way that admission may not win over voters the way the a.n.c. did at the last election five years ago when they took sixty two percent of the vote we just want them to take care of us take care of the take care of a way to train make sure that our kids are having topes listen to what the people

want it's very easy to stand there make promises. it's another thing to actually implement and become the government that people vote for you don't switch up on us because now you and power. another possible winner could be center right democratic alliance leader musi my mana who cast his vote in so went to the cradle of the fight against apartheid but the biggest challenger to the a.n.c. could well be leftist leader julius malema of the economic freedom fighters he's pushed for a redistribution of prime agricultural land much of which is owned by the white minority and now president of the a.n.c. has jumped on that bandwagon himself wanting to accelerate that redistribution and the hope of luring votes away from a lame are. the results of the election are expected by saturday.

well the crease has been covering the selection force and joins us now from johannesburg good to see you in this election is being seen as a verdict on president cyril ramaphosa the a.n.c. party which has ruled the country for a quarter of a century do south africans still have confidence in the party that helped and apartheid. well about ten percent of the votes are already counted and currently the a.n.c. is ahead was fifty four percent of the vote is of course too early to say whether this is a trend or what the final results will be but to does clear that this elections are largely a referendum on president cyrus he took over one year ago promising reforms promising to fight the issue of corruption remember before him jacob zuma was in power and under his watch corruption was rampant and all all levels of governance promised to tackle that issue but of course he will be judged on his performance of very

very soon many observers are saying that he needs at least fifty five or sixty percent of the votes to have a clear mandate is to really clean up within its own party has made a lot of promises but he has to act so far he has established some commissions of inquiry but they haven't delivered results yet and still on the populist for example of the a.n.c. of doing this elections you could see some names that are clearly associated with corruption this is put an exciting election a grin that the a.n.c. will win is not a foregone foregone conclusion tell us how the main challengers in this election have performed. it is very likely that the democratic alliance will once again be the second strongest force and the party is trying to shape their image of a white middle class party but of course people are also keenly looking on what will happen with the economic freedom fighters the self declared

a radical leftist party that has made headlines with rather radical ideas expropriation without compensation for example i'm on nationalization of big companies and they've largely been trying to get the votes from those people who are frustrated we're frustrated of twenty five years of the a.n.c. but many are saying did not bring them to development that they were hoping for. when to expect first results here. for the preliminary results will keep on coming in today for tomorrow but only on saturday we will really have the final results and we will really know how many percent of the votes the a.n.c. and also the opposition parties will get. there in johannesburg thank you so much. now political tit for tat in turkey the main opposition party there the c.h.p. once past election results favoring the ruling party overturned that includes local

as well as national results from twenty eighteen opposition are hitting back after the electoral authorities scrapped istanbul's recent may oral election contest was won by the c.h.p. in a humiliating defeat for the ones a k p authorities ruled the election must be run though due to a technicality your position says the same technicality disqualifies other past results. istanbul's ousted mayor. who has vowed to win the real run of the mayoral election speaking he called the race a wider struggle for democracy in turkey. the elected mayor of istanbul i am a widow already. as mayor i represent the will of sixteen million people and i cannot give up this responsibility because seven members of the election

authority made a wrong decision because. yes there will be a rerun and we will find but if the votes count proves that we've lost the election then we need to accept that it's. this is not only about it and the mashup him this is the largest struggle for democracy so i was elected on the thirty first of march and i will be elected again on the twenty third of june. i'm absolutely sure about that. because the since the fall comes the sick now to our series of reports this week investigating what germans see as the big issues of their time our correspondent kate brady has been traveling across the country to find out what's on people's minds as in many other countries climate change is a major concern in germany and part of the problem is homegrown germany is one of

the world's biggest consumers of coal and four of europe's biggest five most polluting power stations are located right here well at the conclusion of our big issues series cape ready met the germans demanding politicians take action on climate change. to end my journey across germany i'm travelling back to the capitol. where the german government is feeling the heat of climate change. between its love of cars and uclear power phase out and the country's long goodbye to cofield energy japanese struggling to meet climate goals. in recent weeks that very issue has been quite literally knocking on the government's front door. inspired by the swedish climate activists claim to two meg for the past four months hundreds and thousands of german school kids have been skipping school every friday demanding action against climate change university student louise annoyed

power has become the face of the fridays for future movement in germany which is now backed by more than twenty six thousand scientists. we need our government to act now and i don't see that right now we keep burning fossil fuels knowing that they are destroying. and. disturbing our climate to an extent that. we are struggling we will be struggling to stay alive in the long term and species are dying every day. once deemed a world champion in environmental protection it seems germany is at least now realizing that there is more to the fight against climate change the meticulously separating rubbish lushes heat wave alone brought home the harsh realities of climate change cargo ships brought to a standstill dried crops forest fires and damage to infrastructure. having missed is twenty twenty climate goals the german government is now looking ahead to twenty

fifty with the aim of phasing out coal powered energy by twenty thirty eight students likely we want to see the end of that by twenty thirty at the latest and. demonstrators have found to continue striking until they see more action from the government. if in twenty years' time your children or your grandchildren or the children of the neighbors will ask you what did you do back then when will you know what was so could change things where we could make a difference what you do and i'm telling us the government here we were to judge this government. harshly. because we will look back at them and see that they were amongst the last ones who could actually change something and change their the path we are on. knowing the consequences for what's happening after.
