is in washington in an attempt to stop president donald trump abandoning the iran nuclear deal. boris johnson has appeared on a number of us tv networks, including the president's favourite channel fox news, urging him to keep faith with the agreement. the foreign secretary told reporters that the deal had its weaknesses but these could be fixed. the president set the world a legitimate challenge for the world. to stop them getting nuclear missiles and to stop them interfering in other countries, and also fixed the core problem of the deal which it inspires in 2025. and there's no way to stop the iranians getting nuclear weapons very rapidly, but we think we can all fix that,

working with our european friends. we can be tougher on iran but not throw away the heart of the deal which is about stopping them getting a nuclear weapon. our correspondent, barbara plett usher said boris johnson's visit was part of a concerted effort by european countries to keep the iran deal going. the french and german leaders were speaking with the president here recently. basically with the message that the iran deal is not perfect but it is working in that it is preventing iran from getting a nuclear weapon. so, don't throw it away — "we can address the issues of the president in a different way". it seems they are trying to get an agreement or arrangement that will allow the president to say to his base —

which he has promised to scrap the deal — to say what he planned to do, but at the same time keep the deal itself intact. that involves getting the right wording and they are not sure if the president will go for that and we understand that he is leaning towards withdrawing from the deal. mrjohnson is coming here in a last—ditch effort as part of the push by europe to get mr trump to not scrap the deal entirely. with all of this pressure coming to this iran nuclear deal, he will have a lot of attention from the middle east, hoping that mr trump holds firm. yes and no. he will have attention from iran and other countries in the middle east that want the deal to stay in place because they are worried like europe, that if it goes there is a greater security risk in a region that has is already affected by conflict, but two of mr trump's closest allies, israel and saudi arabia,

they don't like the deal, and they have been sending that message to president trump, reinforcing his own instincts on the deal. it's a mixed bag in the region. the message from europe is that this arrangement and this agreement is crucial for the security of the region and also europe because europe is much closer to the middle east than america and that is something that mrjohnson in his own way brought up in his interviews. earlier i spoke to mansour farhang — who's a professor of international relations at bennington college, vermont, and he was also revolutionary iran's first ambassador to the un. he told me that borisjohnson might not be able to sway president trump. the reality is his position which is identical

with those of the majority of experts in the us has not influenced president trump simply because he is not open to fact—based and realistic arguments concerning this issue and he wants to be responsive to his base in the republican party and also a sense of vengeance towards iran. and then there is the government of israel and saudi arabia, and the concerns of the region have to do with iran's political and military influence in the middle east which is a different issue than the nuclear programme which has been very effectively contained. i hope mrjohnson is going to be more influential than many other people who have made the same arguments. we have heard a slightly conflicted message from mr rouhani in iran. he has said getting rid of america's mischievous presence will be fine for iran but he has also said iran has a plan to counter any decision made by trump, so which are

you more concerned with? there was a division within the iranian political elite with respect to the nuclear agreement from the very beginning. the hardliners did not want to submit. but others thought it was in the best interests of the regime and it opens the way for the normalisation of iran's economic and trade relations with western europe. today the hardliners are now saying their prediction about unreliability of the us seems to be the case today. and rouhani in order to demonstrate his commitment to the regime is taking a difficult and hard position towards the us. so his position has got to be understood in the context of factional competition within iran, so it is this with both

sides depending on their audiences and also on the position of president trump in about a week. talking about unreliability and you have said the hardliners have said this about the us‘s unreliability, but what but what about what the president has said, about not living up to the spirit of the deal? i don't know what he means by the spirit of the deal, there was a general wish that this will contain the activities of iran militarily in the region but the reality is since 2003 in iraq and syria, iran and the united states have had a convergence of interests even though there is no written agreement between them but they have been co—operating together.

so as a result of assad's survival iran's influence in the region is becoming a source of concern for the us and israel. it is a perfectly legitimate concern, but that is a different issue to containing iran's nuclear programme. if iran have the capacity to develop a nuclear programme, that will be a threat to europe and the rest of the world. the metropolitan police are appealing for witnesses after two boys were injured by shotgun pellets yesterday in north west london, in broad daylight. police say one of those injured — a 13 year old boy — was hit by accident, while the other victim, who is 15, appeared to have been targeted. our correspondent danny shaw sent us this from the scene of the incident in wealdstone. police have described the latest incident as callous. what appears to have happened, yesterday afternoon, yesterday at lunch a 15—year—old boy was approached by two people

on a motorcycle or mopeds. the 15 year is receiving treatment in hospital after a shotgun incident. a 13—year—old was caught in the crossfire, he is said to be an innocent bystander, walking along with his parents. he is being treated in hospital and has since been discharged. police have been giving more details about what happened today. it was shortly after 115. where two young people on a motorcycle or moped approached, discharged a shot gun towards their intended targets. accidentally injuring a 13—year—old boy who was passing by. it is an appalling cowardly act with no regard to the safety of members of the public who were enjoying a lovely bank holiday weekend. and certainly as a father myself, i can understand how people are extremely concerned for their safety and that of their children.

how badly injured was the 13—year—old? it appears it's a shot gun pellet. he was treated in hospital and he has been discharged and he is now with his family. what can you tell us about the 15—year—old, was he the intended target? it would appear that is the case, but that is part of the investigation. we need to leave that for the detectives to establish. he is still in hospital? he is being treated, yes. what is his condition? it is not life—threatening. he is stable and being cared for by the hospital. he got hit in the head? yes. there was another victim, can you tell us about this other victim? at this stage, we believe there was a third victim, a youth, who received minor injuries to his arm and left the scene prior to police or the ambulance service arriving. we are still yet to speak to him. the incident is the latest in a series of violent incidents across london this weekend in which a 17—year—old

boy has lost his life, fuelling concerns about gangs and guns and knives on our streets. vladimir putin has been sworn in as the president of russia — for the fourth time. during an ornate ceremony at the kremlin, he described it as his life's aim — to do all he could for russia — today's inauguration extends his almost two—decade rule — by another six years. 0ur moscow correspondent, sarah rainsford was watching. from his work desk to his re—inauguration, vladimir putin chose to send a message that today's ceremony is simply the continuation of his long rule. this time, there was a patriotic touch — a brand—new limousine made in russia to carry him across the cobble stones of the kremlin. and then came the pomp and the ceremony. it is the fourth time mr putin has

strode this path through the gilded hall where russian tzars were once crowned. he is now the longest ruler of modern russia sincejosef stalin. once again, vladimir putin pledged to be a loyal servant of his people — after an election that delivered him his biggest mandate yet. translation: thank you for the sincere support i received from the citizens of russia at the presidential election. i view this support as a huge political asset and reliable moral backing. this support gives us faith and hope that russia will continue to boost its power while its people live better lives. but these were the scenes leading up to the grand ceremony. anti—putin protests this weekend across russia. not huge crowds, but young and determined. and demanding change. they were met by riot police as they chanted, "russia will be free."

despite the protests, vladimir putin still commands strong support here. he's achieved that by presenting himself as the saviour of this country — the man who's raised russia from its knees and made it strong again. and that message is very popular here. but a resurgent russia is a major challenge for the west — whether in syria, where russia's military support has kept president assad in power, or in the us, where it's accused of interfering with the elections. there's also the case of the skripals — an ex—russian spy and his daughter poisoned in salisbury with a nerve agent developed by soviet russia. moscow insists it knows nothing. and, as president putin takes office again, there are no signs yet that confrontation with the west will end. and no real pressure from the russian people either for mr putin to alter his political course. the headlines on bbc news:
