hello and welcome to bbc news. state media in russia is reporting that president putin has visited mariupol — the ukrainian city which was captured by invading russian forces last year. the tass news agency says he travelled there by helicopter, and visited local residents. if confirmed, it would be mr putin's first trip to the ukrainian territory which has been occupied by russia since the invasion was launched just over a year ago. we've received these pictures, which we understand to be mr putin in mariupol on saturday evening. he's shown driving around in a car,

and also visiting what appears to be a child ren�*s playground. possibly one that has been renovated, there appears to be work still going on. it looks like some kind of tractor is one of the children's rides that is perhaps being opened. the visit came at the end of a week when the russian president was charged by the international criminal court with forcible abductions of ukrainian children. and on saturday, mr putin also visited crimea — the region which russia first invaded and then annexed nine years ago. live now to our diplomatic correspondentjames landale in kyiv. he has looked at these pictures. what do you make of this visit? the timin: is what do you make of this visit? tue: timing is important, what do you make of this visit? tte: timing is important, a couple of days after president putin was accused by the international criminal court of being a war criminal court of being a war criminalfor the alleged

criminal court of being a war criminal for the alleged deportation of thousands of children from occupied ukraine russia. throughout this conflict whenever there is some kind of setback or something that has been done to russia, vladimir putin tends to respond, sometimes militarily, sometimes diplomatically, sometimes with public images and that is what we see here, public images that he wishes to show after the international court made the accusation against him on friday. yesterday he was in crimea, today he was overnight in mariupol. essentially producing pictures that all these pictures, from cyprus on state television but images that show today at town but is apparently being reconstructed after the devastation of last year at the hands of russian artillery and air strikes. he is shown talking to residents who seemingly seem to be happy with the new buildings that

have been made, shown in the pictures, the playground. i think this is a sense of mr putin saying the international community can say at do with it once but in russian occupied crimea it is business unusual as life is getting back to normal, that is the imagery he wishes to portray so it is a bit of business as usual, a bit of defiance but we should know these pictures are taken amidst hugely tight security, they take place most of them into darkness. he has been driven around and there are residents seemingly standing in a group on the side of the street in the middle of that darkness, so as ever these are carefully controlled images we are getting. presumably if ou do it at images we are getting. presumably if you do it at night _ images we are getting. presumably if you do it at night it _ images we are getting. presumably if you do it at night it reduces _ images we are getting. presumably if you do it at night it reduces the - you do it at night it reduces the risk of unexpected encounter with a civilian who happens to be out doing their shopping because it does look very quiet. what about this

announcement on friday, the icc, partly the defiance to say i don't go about this court, i am able to move freely in ukraine, i wonder if even the existence of that warrant might complicate any prospects of any future negotiated settlement because the icc is independent of government so presumably even if there was a deal that ended the war that icc warrant would remain live. the icc warrant remains live, until such time that either vladimir putin is arrested and subsequently potentially faces trial for when vladimir putin dies. there is no time limit. one would assume that warrant can constrain his travel to the 123 member states and countries around the world that sign up to the authority and jurisdiction of the

international criminal court because if he steps foot in any of their territory those member state governments are obliged to try and arrest him and then make sure he is sent to the hague for trial. that at the moment seems unlikely, until such time potentially who knows what will happen in the future, it would require a lot of political change i imagine in moscow. in the meantime i think mr putin is showing that in some areas, crimea, mariupol, you can still travel as freely as he wishes and he can visit and show those parts of mariupol that he wants to show our being reconstructed because this, when i say this is defiance, this matters because the city for ukraine is a symbol of its resistance from last year, that might be one of the reasons why he has visited. thank ou. a deal brokered by the un and turkey

allowing the export of ukrainian grain from the black sea has been renewed — hours before it was due to expire. kyiv says the agreement will continue for four months — while moscow claims it agreed to just 60 days. the grain initiative was first brokered lastjuly, during fears of a global food crisis — after moscow blockaded ukrainian ports. russia and ukrainejointly account for nearly a third of global wheat supplies — with ukraine's contribution nearing 10%. some financial news — and talks are taking place in switzerland about a possible takeover of the troubled bank credit suisse. it's understood that the country's biggest bank, ubs, is in negotiations to buy all, or part, of the organisation. credit suisse had been caught up in the market uncertainty triggered by the collapse, nine days ago, of america's silicon valley bank. analysts say a takeover deal by ubs could be finalised before the markets re—open on monday.

lananh nguyen is us finance editor for reuters in new york — she says there are some hurdles to cross before any takeover could take place. there are actually many provisos, so the first is what we just recently and exclusively reported, which is that ubs is seeking 6 billion in government guarantees for credit suisse in order to do a deal. there is a lot of risk around this deal in terms of credit suisse's troubles and what we understand from the government and parties in both countries are really trying to hammer out some of the terms here and the us is i think driving quite a hard bargain because there are lots of risks to the company, there are many employees that might need to be laid off, top of which there is litigation risk against credit suisse, so there is a lot still happening, it is a fluid situation and there is no guarantee of a deal at all right now, so the situation

could change entirely, so we are following this very, very closely. our transactions in backing a very complex and very thorny and they require a lot of rocketry oversight and on top of which they require a lot of deal—making between the two companies so it is not duty this quick but at the same time we are facing unusual and extraordinary times in the banking industry where two national champions in suits and are looking for a potential deal to merge so this is what authorities and companies will get creative as we have seen in the us financial crisis during thousand eight what the normal rules do not apply here. the former us president, donald trump, says he expects to be arrested on tuesday — and has called on his supporters to protest. in a post on his own social media platform, he claimed to have seen leaks from the manhattan district attorney's office — which is yet to comment. mr trump is accused of paying hush

money to an alleged mistress. here's our north america correspondent david willis. four months after he announced a third run for president, donald trump could make history for a rather different reason. responding to speculation in the american media, he took to his own platform, truth social, to level a capslock chorus of accusation against the manhattan district attorney, whose office, mr trump believes, has been leaking news of his imminent arrest. central to a long—running investigation undertaken by the da's office is the porn star known as stormy daniels. prosecutors have been looking into whether mr trump made illegal payments in order to buy her silence before the 2017 presidential election, following a brief affair. that, he denies, but it is the final five words of that social media posting that have proved particularly disconcerting to some. "protest," he writes. "take our nation back." a message chillingly similar to one he delivered shortly before

the uprising at the us capitol building on six january, 2021, which saw a violent mob of trump supporters lay siege to the seat of government. senior republicans have rallied to mr trump's defence. on twitter, the house speaker kevin mccarthy said arresting the former president would amount to what he called an outrageous abuse of power. but his democratic opponent nancy pelosi branded mr trump's social media message reckless, saying its aim was to keep himself in the news and ferment unrest amongst his supporters. for voters in mr trump's home state of florida, mr trump's legal team say they have received no indication of their client's impending arrest, but he is facing legal battles on a number of other fronts as well. america 45th president could become the first one ever to be charged with a crime.

it has been a busy week with the jeremy hunt and the controversy of trying to avert the departure of senior doctors, and looking ahead questions as to what will happen when borisjohnson appears for privileges committee to defend himself against allegations he misled parliament, perhaps the most serious charge that can be made against perimeter. our political correspondent, tony bonsignore, joins me now. it wasn't the chancellor or the prime minister this week for laura kuenssberg's programme, it was all dowden, one of the cabinet ministers with a title that nobody really understands but he is a bit of a backroom fixer, has he been involved in trying to fix it series of public sector space? in trying to fix it series of public sector space?— in trying to fix it series of public sector space? whose official title is chancellor _ sector space? whose official title is chancellor of _ sector space? whose official title is chancellor of the _ sector space? whose official title is chancellor of the duchy - sector space? whose official title is chancellor of the duchy of - is chancellor of the duchy of lancaster and we just call him cabinet minister. he was asked about

this on laura kuenssberg's programme, he is a senior cabinet minister, close to the prime minister rishi sunak, there were a couple of questions, what happens in terms of other disputes given that we had agreement, yet to be ratified but that agreement on thursday. he said the government is always keen to talk to different groups in terms of pay, but given a number of months the government wasn't prepared to engage on paper towel with public sector unions, but also about where the money is coming from. that i think, there are still questions to be asked. what oliver dowden said was the money would be found for these greater than anticipated increases, it wouldn't come out of front line services, it might have to come out of efficiencies but that would come in due course. {jut

to come out of efficiencies but that would come in due course.- would come in due course. out of their own departmental— would come in due course. out of their own departmental budgets, | would come in due course. out of. their own departmental budgets, not out of the treasury? hat their own departmental budgets, not out of the treasury?— out of the treasury? not entirely clear. out of the treasury? not entirely clear- the _ out of the treasury? not entirely clear. the only _ out of the treasury? not entirely clear. the only guarantee - out of the treasury? not entirely clear. the only guarantee beingl out of the treasury? not entirely - clear. the only guarantee being made as it won't affect front line services. but i think that is not only important looking further down the line but other unions come to perhaps negotiate with the government and they might want some guarantees that there will be extra money on the line because it isn't just about pay, it is the state of public services as well. this feels like a lifetime _ public services as well. this feels like a lifetime ago, _ public services as well. this feels like a lifetime ago, we _ public services as well. this feels like a lifetime ago, we used - public services as well. this feels like a lifetime ago, we used to i public services as well. this feels i like a lifetime ago, we used to talk about pay relativities, once you go from one settlement, people say our job is an allergist to the job and we should get the same. exactly at the government, _ we should get the same. exactly at the government, when _ we should get the same. exactly at the government, when the - we should get the same. exactly at - the government, when the government was holding out, that was part of the co—creation because once you give it to one, once you make a settlement with the union others will look for the same, so there are these intensive negotiations going on now between the government and teachers and junior doctors but they

are not the only strikes, across the economy, university lecturers, passport office workers, they will be looking closely. in passport office workers, they will be looking closely.— be looking closely. in terms of lookin: be looking closely. in terms of looking ahead _ be looking closely. in terms of looking ahead this _ be looking closely. in terms of looking ahead this week, - be looking closely. in terms of looking ahead this week, i - be looking closely. in terms of. looking ahead this week, i don't think anyone doubts that boris johnson's appears for the is going to be the big story is going to be the big story of the week and arguably a slightly awkward one for the government because he is a conservative mp, a former prime minister, many of the ministers in the cabinet now served happily in his cabinet for many years, and yet he is a bit of a liability potentially for the image of the party now. potentially for the image of the party nova— potentially for the image of the -a now. , . ., , , party now. yes and i am sure rishi sunak would _ party now. yes and i am sure rishi sunak would rather _ party now. yes and i am sure rishi sunak would rather not _ party now. yes and i am sure rishi sunak would rather not this - party now. yes and i am sure rishi sunak would rather not this week i sunak would rather not this week that we were talking about parties held or not held during covid lockdown spot that is what we will be talking about, this mammoth session we expect on wednesday afternoon, a key moment for boris johnsonfuture westminster, oliver dowden a cabinet minister was asked about this and he was very close to borisjohnson, one of his chief

lieutenants, asked about what to expect and this is what he said. i've known borisjohnson reasonably well over the years. i'm quite sure that he will put forward a robust defence of his conduct. it will then be for the committee to make that determination and if necessary, the house of commons to make that determination. i think that's the the proper process to go through. boris johnson's team borisjohnson�*s team has been out in the papers today, talking about the dossier they will produce which they say will clear the prime minister, might not be that simple. i suspect the seven mps on the privileges committee might have other ideas. thank you. that will be one to look forward to and we will bring it to you here on bbc news on wednesday. the uk's agreement with rwanda about sending illegal migrants there has been updated, so that it covers more people. on a visit to the country's capital — kigali — the home secretary said the deal has been strengthened. yesterday, suella braverman was given a tour of potential migrant housing.

at least 1a people have been killed, after an earthquake in ecuador. 13 of the casualties were in and around the southern province of el oro — and one young girl also died in northern peru, when her family home collapsed. the us geological survey says the tremor had a magnitude of 6.8. the effects were widepsread — including the collapse of this building, a museum, which was mounted on a pier at the seaside. it had stood on the same spot for more than 60 years. the european union's top diplomat has announced agreement between serbia and kosovo on how to normalise relations between the two countries. belgrade has not recognised kosovo's independence since it was declared 15 years ago. speaking after 12 hours of talks,

the eu's foreign policy chief, josep borrell, told a news conference in north macedonia that the deal would bring significant benefits for both sides. i want to stress that to open the path towards reaching the strategic objective ofjoining the european union, serbia and kosovo need to normalise their relations. there is no way around it. and this agreement and this annex, which is integral part of the agreement, it's an important step forward in order to make it a reality. and we will continue working tireless until we reach a comprehensive agreement on the normalisation of their relations. our balkans correspondent guy delauney explains the significance of these agreements.

they're still going to have to carry on talking until kosovo and serbia reach this normalisation agreement. so it's not the end of the road. i mean, somebody was saying to me last night, this is a map to a road map to a direction towards an agreement. and it feels a little bit like that at the moment. what we have got agreed, according to the european union, is an annex on the implementation of an agreement for kosovo and serbia to normalise their relations. and when you look at both this annex and the agreement, they're extremely light on detail. and straightaway, mr borrell was saying that, for example, kosovo is going to enter into negotiations on arranging some sort of limited autonomy for the ethnic serb minority in kosovo. but it's got to negotiate that, it hasn't actually been agreed. so i think what we're going to take away from this is things are still moving forward, but a lot is still in play and a lot still has to be explained to the people of kosovo and serbia by their respective leaders. in israel, protests

against the government's plans to curb the supreme court's powers have entered their 11th week. tens of thousands of israelis have taken part in more nationwide demonstrations. opponents of the planned reforms have accused prime minister benjamin netanyahu — who is on trial on corruption charges — of trying to use the reforms to quash possible judgments against him. he has rejected the accusation. a doctor working in ukraine says bandages made at a factory in the uk are helping to save hundreds of lives. the dressings, which are coated with an extract that comes from shrimp, can stop intense bleeding. matthew hill reports. dr irnya rybinkina puts her life in danger every day in ukraine, helping the victims of the war. at times she has to treat very traumatic injuries. the first thing you do is put a tourniquet on, and then you try and stop the bleed

by packing the wound. this production line in bridgwater has been playing a vital role in helping medics like dr rybinkina save lives. the bandages, made by the firm nonwovenn, are then incorporated into first—aid kits by another british company. we manufacture millions of these, our customer—made trade have sent tens of thousands, that we know of, out to the ukraine already. the secret of their success is down to this tiny shellfish, the shrimp. mariners have known for hundreds of years that shrimp shells are good at stopping bleeding, and the extract from them, known as chitosan, is woven into the company's bandages. i can demonstrate. if ijust dip it into water, it's infused with shrimp extract from shells, and that gradually becomes very sticky to the touch. ultimately, that forms an artificial clot. the ukrainian military rang

nonwovenn shortly after the invasion and began asking for as many bandages as they could make, and the demand continues. so it has been saving lives, you think? it has been saving a lot of lives, thousands of them. we get a lot of feedback from the people who are using them. they send a message saying, "you know what? "yourfirst—aid kit, it did save lives. "someone got there and we used the tourniquet and the celox and the gauze and everything, and the person actually arrived alive at the evacuation point. since i interviewed dr rybinkina, she was involved in a serious road traffic accident on her way back from duties, and is now being treated for a broken arm. but she remains undaunted, and hopes to be back on the front line treating more casualties with these bandages as soon as possible. a lot of friends have been lost in this war, and the human toll is horrendous.

matthew hill, bbc news. the popularity of wild swimming has really taken off in recent years — with both the physical and mental benefits being widely publicised. researchers in the uk say they now know why the pastime can significantly improve your mood — after studying brain function, following cold water immersion. edward sault has been to meet one group of swimmers on the isle of wight. it is 3 degrees air temperature, 7 degrees in the water, and it's time for me to get in the sea with these swimmers from swim the wight. i have a chronic kidney and bladder issue, back pain also — i take a lot of painkillers — and this really helps.

i get a real calmness when i come here, and it's where my head, actually, it's probably the only real place it switches off. i feels really amazing, | really awake and alert. ijust love it. clears the brain of any sort of thoughts you don't need. just, like, had a mental, physical reset. swimming is something i've done all of my- life, i absolutely love it. and when i get out of the water — especially this time of year — i really feel buzzing. and now researchers from bournemouth university, the university of portsmouth and university hospitals dorset says there is scientific proof. we had participants come down to the lab who are completely naive to cold water swimming, so they weren't exactly pro athletes, they were your average people. we got them in the scanner next to us here, then they hopped out of the scanner, very quickly got into a cold water bath that we had prepared, they were in there for about five

minutes and then we got them back out, towel—dried them, back into the scanner. it potentially opens new avenues for us, for potential treatments for some of the mental health disorders that are plaguing us at the moment. back in the water, and the chilly temperatures are not putting anybody off. i think it's a little bit like having a computer, switching it off and on again. nothing matters when you're in the water. it gives you some sort of buzz, and the colder the water, the bigger the buzz. these swimmers will be back here tomorrow for another dose of vitamin �*sea'. edward sault, bbc news, on the isle of wight. a reminder of our top story — vladimir putin's first visit to territory in ukraine which russia seized after its invasion. these images have emerged of him driving into mariupol — he flew there by helicopter, after visiting crimea, a ukrainian territory which russia

seized nine years ago. mr putin's visit was unannounced, and details of it only became public on russian state media once he had returned to russia.

this is bbc news, the headlines: president vladimir putin visits mariupol — the ukrainian city which was captured by invading russian forces last year. it is his first trip to the russian—occupied territories of eastern ukraine's donbas region since the start of the war. switzerland's biggest bank, ubs, is in advanced talks to buy all or part of its troubled

rival, credit suisse. credit suisse is the second largest bank. regulators are trying to facilitate a deal before markets reopen on monday. former us president donald trump says he suspects there are plans to arrest him on tuesday — he's called on his supporters to protest. prosecutors have been looking at a possible indictment of mr trump. kosovo and serbia have tentatively agreed on how to implement a european union—sponsored plan to normalise their ties. the deal on saturday came after 12—hour talks between kosovo's prime minister, serbia's president and eu officials. the eu's high representative for foreign affairs, joseph burrell. more from me at the top of the hour. now it's time for the media show: writing a first draft of history. my guest today has covered some of the most defining stories of our time. gary younge briefly became part of nelson mandela's entourage, joined revellers as president obama was elected, and has covered much else too —

gay marriage, brexit, the windrush scandal, and the black lives matter movement.
