—— the wagner leader goes on to say that the war has been a disaster, needlessly sacrificing by seeding ukraine's resources. he says this is not a coup. they've been shooting at us. they've been shooting at us. they've been shooting at us. they've been shooting at them. it's been going on for eight long years on february 2a there was nothing extraordinary. now the russian defence ministry is trying to deceive the president and the public claiming there was insane aggression and that they were going to attack us along with the attire nato

block. so the so—called special military operation on february 24 military operation on february 2a was launched for a completely different reason. live now to vitaliy shevchenko from bbc monitoring. we are hearing reports of tightened security we are hearing reports of tightened security measures we are hearing reports of tightened security measures in moscow what are you hearing? what this means in practice is that troops seem to be deployed to moscow streets. i have seen footage, various video clips and still pictures of armoured personnel carriers, military trucks on the streets of moscow. there are also reports of russian troop movements which is in a russian region in the south right next to ukraine. apart from that the situation seems to be

relatively calm at the moment. in a sign that the authorities are taking his statements really seriously, the russian state tv�*s channel one which is one of the two most important tv stations in russia has interrupted its programming about half an hour ago to broadcast emergency news bulletins which is basically a recap of various official statements denying that russian military attacked wagner and claiming that you guinea pig ocean video which he stated was the alleged aftermath was fake. on social media importantly there is channels are circling, to video clips containing

addresses to wagner made by two russian generals. one, who until earlier this year was in charge of the russian military operation in ukraine. he addressed wagner and called on the most —— the mercenary group to stop it. he said stop the convoys and return them to bases which suggest that wagner may be on the move. the second general which is deputy head of the russian military intelligence, he spoke of a military coup and he said what is happening is a stab in the back for russia and its president.— back for russia and its president. back for russia and its resident. ~ , . president. we share the -- we should say _ president. we share the -- we should say that _ president. we share the -- we should say that prigozhin - president. we share the -- we should say that prigozhin has i should say that prigozhin has said this is not a cube how

a military coup in russia and prigozhin denies it. he is not a political activists or a political party leader, he is someone who has a huge potieria arsenal at his disposal with tanks and helicopters so he's definitely a force to be reckoned with. fix, definitely a force to be reckoned with.- definitely a force to be reckoned with. �* . , ., ~' reckoned with. a what you think this means _ reckoned with. a what you think this means vladimir _ reckoned with. a what you think this means vladimir putin - reckoned with. a what you think this means vladimir putin and i this means vladimir putin and his grip on power? it’s this means vladimir putin and his grip on power?— his grip on power? it's clear to me that _ his grip on power? it's clear to me that none _ his grip on power? it's clear to me that none of- his grip on power? it's clear to me that none of this - his grip on power? it's clear to me that none of this was| his grip on power? it's clear. to me that none of this was in his plans. it's true that throughout his reign in russia, he maintained this finely balanced system where different centres of power and influence were played against each other so it was argued that the russian defence minister was

played against yevgeny prigozhin so neither could become too powerful challenge vladimir putin but it's reasonable to assume that now the system has gotjust balanced and the fact that russian state tv has started to broadcast statements critical of yevgeny prigozhin, this is unlikely to happen without sanction from the kremlin. so this suggests a degree of unhappiness on vladimir putin is par with... unhappiness on vladimir putin is par with. . ._ is par with... the kremlin say they are _ is par with... the kremlin say they are monitoring _ is par with... the kremlin say they are monitoring the - they are monitoring the situation and will be

"i have given everyone the same honest advice which is that

until a sub is classed, tested and proven it should not be used for commercial deep dive operations." he went on, "as much as i appreciate entrepreneurship and innovation, you are potentially putting an entire industry at risk." "so i implore you to take every care in your testing and sea trials and to be very, very conservative." stockton rush replied... "i have grown tired of industry players who try to use a safety argument to stop innovation and new entrants from entering their small existing market." the bbc�*s north america correspondent nomia iqbal is in newfoundland where canada's set to lauynch an investigation. is in newfoundland where canada's set to launch an investigation. the transportation safety board of canada is going to investigate what happened involving the polar prince and the submersible. both are privately owned vessels, but the polar prince, vessels, but the polar prince, the mothership which launched the submersible over the weekend, is canadian flagged. so the transportation safety board is compelled to to conduct a safety investigation. there will be teams travelling here to saint

john's in newfoundland. they will be gathering information and carrying out interviews and assessing exactly what happened. the coastguard has, as we know, confirmed that the submersible was destroyed in a catastrophic implosion. the navy, the us navy has since come out to say that on the sunday they heard a noise that was consistent with an implosion and they passed it on to the us coastguard. the coastguard says that it still carried out that large search and rescue operation we saw because the data wasn't definitive. and just to add, we understand there's also going to be an investigation involving the national transportation safety board and the us coast guard. also, vessels are going to start returning from the atlantic here into saintjohn's, and that includes the polar prince. some vessels will, however, remain because they're involved in the recovery operation. the us coast guard has already said that they... the chances of retrieving the bodies of the five men is pretty impossible in the ocean. but they do want to keep investigating and finding out what happened in order to bring

some closure to the families. around the world and across the uk. this is bbc news. nara is showing me a laminated photo of her then two—year—old son from a set she had when she was on an isolation ward in bristol during her treatment 30 years ago. i was consciously aware that, if i died, he wouldn't remember me and i didn't want that. despite chemotherapy, nara's cancer came back aggressively and she says she was the first patient with hodgkin's lymphoma to be offered a stem cell transplant in bristol. i knew that it was very serious at that point. i'd been told that my cancer was very aggressive and aggressive treatment was needed. it has led to other health problems for nara throughout her life, but she says she's grateful to have survived longer than expected as a result of the doctor's pioneering

work in the early �*90s. and i increase the numbers every year, every year that i live, and without the unstinting support of the nhs, i certainly wouldn't be here today. for more stories from across the uk, head to the bbc website. you're live with bbc news. the us supreme court on friday handed the biden administration a major victory on a key immigration case — ruling that republican—led states do not have the legal right to challenge a policy concerning federal immigration enforcement. the justices in a rare 8 to one ruling cleared the way for the biden administraiton to re—instate rules prioritising the deportation of immigrants based on serious criminal records, national security threats, and migrants who recently entered the us. the policy generally shielded unauthorised immigrants who have been living in the us for years from being arrested by ice if they did not commit serious crimes. in their lawsuit, texas and louisiana claimed the biden administration policy caused direct harm because of increased costs for social services, including health care and education.

joining us now to discuss this is greg stohr, bloomberg's legal correspondent. what does the railing on this case telus? it tells us that the president has a fair amount of discretion and immigration enforcement and the court aren't going to second—guess that. the wait was cast by the justice kavanagh, this is the president making a prosecutorial decision and the homeland department making a decision on who they are going to arrest and deport. it's not something that anyone outside the state can sue or challenge. does this ruling make it harder for states to challenge federal laws moving forward, or is this case unique? the justice said thejustice said it's an unusual lawsuit. trying to get the administration to arrest

more people. so whether it applies in a different context we will have to see but building on a year ago, it does suggest that the supreme court is taking a hands— off approach to immigration enforcement. this would appear to be a win for the biden administration. it certainly is, legally. there is no question about it. at the top, they want to prioritise, we're going to go after people who are especially dangerous, people entering the country recently and now they will be able to do that.— recently and now they will be able to do that. how rare is it seen as one _ able to do that. how rare is it seen as one verdict _ able to do that. how rare is it seen as one verdict in - able to do that. how rare is it seen as one verdict in a - able to do that. how rare is it. seen as one verdict in a court? it happens. what seems unusual to me about this is that about a year ago, the supreme court kept the policy on hold and that was a 5—4 decision and there was a shift on the court. once they looked at the merits of the case they decided, no,

we're going to side with the administration. irate we're going to side with the administration.— we're going to side with the administration. we are awaiting two ma'or administration. we are awaiting two major rulings _ administration. we are awaiting two major rulings from - administration. we are awaiting two major rulings from the - two major rulings from the supreme court, one is affirmative action and the other is on student debt. what do you expect to see their? well, we will have to see. they are very big cases. the court certainly suggested in early arguments that they are going to stop universities from using race as a factor in admissions. they have been able to do that for about 50 years. there is a lot of scepticism in this court either that because this is more conservative than in the past. there's issues around for giving loans for 4 million people. there is a standing issue there. it's possible the court will say that the states challenging the policy don't have the right to challenge that either. if the administration is gonna win the case then that's probably how it will go. case then that's probably how it will to. ~ ., ., i. case then that's probably how it will to. ~ ., ., ,, it will go. what do you think this will mean _

it will go. what do you think this will mean that - it will go. what do you think this will mean that the - this will mean that the president politically? they are certainly very _ president politically? they are certainly very important - president politically? they are certainly very important in - certainly very important in terms of a policy standpoint. the student loans more than affirmative action because it's his initiative. student loans is something that he made a priority. we will see how it plays politically. if the court strikes it down then they will say at least they tried and it was the court that stopped us. thank you forjoining us on our programme tonight. we are getting some development on the story that is coming in as we've said, there some developments happening in russia. we've got a statement from yevgeny prigozhin which hasjust been coming in. this is the head of the wagner mercenary group. he said" we've

crossed russian state border in various locations. we are entering washed off. those who intend to stop us, step aside." we've been hearing this statement from yevgeny prigozhin head of the wagner group. we haven't been able to verify this. we are working on that and we should have that for you. that and we should have that foryou. significant for you. significant developments taking foryou. significant developments taking place in russia. it's saying that tension is rising. russian state media has said that security has been stepped up on the streets of moscow. we spoke to correspond that there earlier and he said that on social media in russia there are reports, not only moscow also in rostov that there are some troops on the streets who have been protecting and securing the streets there. we've also seen russian state

media interrupted regular programming to talk about yevgeny prigozhin statements. according to the kremlin, vladimir putin is aware of the statements that yevgeny prigozhin has made and we expect to see russian authorities condemn that. they've ordered the arrest of yevgeny prigozhin accusing him of inciting civil conflict. they have urged their fighters not to comply with his what they've called criminal attempts. more on that for you attempts. more on that for you at the top of the hour. thank you for watching bbc news.

as we head into sunday we will see some thundery downpours swinging in from the west. courtesy of the frontal system which is way ahead of the west of us. short term high pressure is in charge and around this area of high pressure, particularly as these weather fronts squeezing we've got a feed of humid air wafting its way across our shores. a humid start to saturday morning. some murky, misty conditions around the hills. a bit of rain moving across the far north—west of scotland. there is a small chance of a shower in northern england down into the midlands but in the south of england there will be the lion's share of the sunshine. a warm day, 2a degrees for belfast, 25 for aberdeen, 29 for london. that doesn't head as we go into the

evening. 23 celsius in london and sheffield at 10pm in the evening. a little bit uncomfortable for sleeping. those temperatures falling in the early hours of sunday but with the humid air in place, sunday is going to turn into a very warm day. however this frontal system in the west will bring heavy, thundery rain across northern ireland. that will push its way eastwards and some showers will pop up across northern england, eastern scotland and these could be heavy and thundery in nature. in the south—east, largely dry with sunshine and that warmth being squashed into the south—east corner. temperatures in london likely to reach 31 celsius. pressure in the west and that fresher air will move across the country into the start of the new weight. further frontal systems lying in wait so further outbreaks of rain at times and potentially

strong winds towards the north and west of the uk. not as much rain and not as warm as it has been.

this is bbc news.

we'll have the headlines and main news stories for you at the top of the hour after this programme.
