croatia are the first team to make the semifinals and they are joined by argentina, who defeated the netherlands also in a dramatic penalty shootout. our sports correspondent olly foster has all the details from doha. what has all the details from doha. is simply extraordiné to what is simply extraordinary start to the quarterfinals we have had. both teams had to come through absolute nailbiter is. croatia, they were the penalty kings in russia four years ago. they came through to penalty shoot—out on the way to the final there. and they have come through two penalty shoot—out here to get to the semifinals. they knocked outjapan and now they have knocked out brazil as well. it was goalless at the stadium against the five—time world champions. neymar put brazil ahead in the first period of extra time. petkovic equalised and sold went to the shoot—out. croatia, perfect with their four spot kicks. the saved by

dominik livakovic, it was down to marquinhos and he hit the post. there were tears and prorations celebrated. they are an ageing team, but they march through to the semifinals, will they will face argentina. and again this was an astonishing match. argentina looks to be cruising towards the last four. they were 2—0 ahead. messi at the heart of everything. he laid a beautiful pass for melina to put them up at the break. messi then scored a penalty. within a master truck by louis van gaal, the netherlands head coach. he brought on wout weghorst, the burnley striker unknown in turkey. he scored a wonderful header in the last ten minutes into their was ingenious free kick. he picked it up inside the box and beat emiliano martinez in the hundred and tenth minutes.

2-2, that in the hundred and tenth minutes. 2—2, that went to penalties as well, and that is where argentina prevailed —— 110th minutes. martinez saving the first two and it all came not to look to your dash make it all came down to lord tyrell martinez. we now wait and see if the next two quarterfinals can live up to what we have seen today on friday —— it all came down to lautaro martinez. olly foster there. well, there were scenes ofjubiliation in croatia as the national team knocked brazil out in that penalty shoot—out. guy delauney has been soaking up the atmosphere in zagreb. they are toasting the name of dominik livakovic here in the centre of zagreb. all of these bars still pretty much packed out after the match, the quarterfinal of the world cup against brazil, which croatia won on penalties, as they tend to do.

and dominik livakovic did what he tends to do, which is save those crucial kicks. croatia on the other hand proving extremely resilient in their own spot kicks. and talking to the fans throughout the course of the day and even during the match, and even when it looked desperate for croatia in the second half of extra time, when they were 1—0 down, they kept saying to me, "look, we will score a goal, we will take it to penalties. "we believe." what is even more, they believe they can go all the way to the final. people are saying to me, "we went all the way to the final. this time, we are going to do it again, but we are going to win it." guy delauney there in croatia. for every winner, there is a loser. for brazil, this was a devastating defeat, crashing out of a tournament many believed they could win. here's katy watson in sao paolo. you can hear the band has started up, musicians presumably booked to celebrate a win for brazil, going through to the semifinals, but now they have been booked,

they may as well enjoy the party. you can see people sitting behind me. it's an unbelievable result for the brazilians. they were so convinced they were going to win this game and go through to the final. i've never seen such confidence from a nation. football means everything to brazilians, and especially after a difficult few years politically, with so much division. i was talking to one woman who said that brazil comes together with football. it doesn't matter about class, race, politics or religion, that brazil comes together when there is a world cup. and in fact, they take the day off. nobody worked because football matters so much, but instead they are going to have to find another team to support. i was talking to one couple who said they will now be supporting croatia. they beat brazil, they're a good team to support, they say, but the mood is definitely heavy. my partner has just walked up to a kids party. he says it feels like they have double booked it with a funeral. it'll take some hours, some days for that mood to lift. katy watson, just putting that into

context, the defeat for brazil. lots more on our website on the world cup. one of russia's leading opposition politicians has been jailed for speaking out about russian war crimes in ukraine. ilya yashin told his supporters not to worry about him as he was led away for his eight and a half year sentence. from moscow, steve rosenberg reports. handcuffed and locked inside a glass cage as if a dangerous criminal. but ilya yashin is a russian politician, a fierce critic of vladimir putin. he had been put on trialfor talking publicly about evidence of russian atrocities in the ukrainian town of bucha. thejudge convicted him of spreading fake news about the russian army and sent him to prison for eight—and—a—half years. "don't worry," he told his supporters, "it's ok." outside the courthouse, "freedom," they shout.

but just a tiny few. perhaps this is why. eight years of prison is a lot. some people that murder someone may get less. so it's understandable why not many voices you hear now like yashin�*s one. the trial that has now ended here reflects the growing wave of repression in russia since vladimir putin invaded ukraine. the message from the kremlin to its critics, to its opponents, is clear — "stay silent." later, vladimir putin was asked for his reaction to the eight—and—a—half—year prison sentence. "isn't that brutal?", asks the journalist. the president's reply... "casting doubt on the decision of a court is inappropriate." in a statement, ilya yashin said this — "strong leaders

are calm and confident. only weak ones try to silence people." steve rosenberg, bbc news, moscow. president putin has said further prisoner swaps with america could be possible, if the two countries can continue to reach a compromise. his comments came after the release of the american basketball player brittney griner, in exchange for the convicted russian arms dealer viktor bout. the athlete appears to be in good health after returning home from ten months detention in russia. she will now undergo medical checks in hospital in texas. the us political world has been shaken up for a second time this week, after democratic senator kyrsten sinema said she's switching her affiliation to independent. the news comes just days after the democrats secured a 51 to 49 seat majority in the upper chamber. sinema has ruffled feathers

within the party, not always going along with the policies of president biden. here's our washington correspondent anthony zurcher. —— and we do have much more on this on our website. let's get some of the day's other news. gunmen in northern nigeria have abducted the family of a local member of parliament in the state of zamfara. people in the town of jangebe say the kidnappers broke into the home of the politician, aminu yusuf ardo, during the night and seized his wife and four children. the iranian president has said his government will continue its operations against protesters, a day after the first execution over the nationwide anti—government unrest. ebrahim raisi said the identification, trial and punishment of the perpetrators would be pursued with determination. president xijinping said china is looking to cooperate with saudi arabia and other gulf

were taken away. are you saying they are not telling the truth? we would welcome them to come to us, tell their true story. bangladesh's prime minister sheikh hasina has dismissed accusations her government is responsible for human rights abuses. we have spoken to a number of people who have shared allegations of violence and intimidation by the security forces. many of them say they are too scared to go on camera for fear of reprisal. shafiul islam kajol�*s story is one reason why. he says he was tortured in an underground detention cell, handcuffed and blindfolded for more than 50 days before he was released. the journalist says it was after he published an investigation into government officials. bangladesh's home minister says it is all untrue. translation: they asked me why i wrote the story. - i was tortured and interrogated for hours at a time. it was horrible.

opposition figures, ilya yashin, has been jailed for eight—and—a—half years for spreading so—called "fake news" about the country's military. now a few minutes ago, we reported on the story of us democratic senator kyrsten sinema. she's said she's switching her affiliaton to independent. with more on that, here's out washington corresondent anthony zurcher. well, kyrsten sinema has always had a bit of an independent streak. she started her time in politics in 2000 supporting ralph nader's independent presidential bid. she was a member of the green party for a while, before becoming a democrat and running for office. but i still think that this decision, this announcement, caught a lot of democrats in washington off guard. they knew that she had broken ranks with democrats over the past two years to vote against some ofjoe biden�*s political imperatives, some of his legislative agenda, but they still viewed her as a member of the party.

the reality, though, is that even though she is now a registered independent, she still is going to work with democrats in the us senate, and that will effectively keep their majority secure, it will keep them in control of senate committees, which is something they gained with their recent 51st victory, with raphael warnock winning in the senate in georgia. where i think this really could come into play is in two years. if krysten sinema runs for re—election, her senate seat is up in 2024, and she was not popular among democrats there, it looked like she was going to be facing a primary challenge from a democrat before facing a general election republican opponent. this may set her up to run for an independent bid for that senate seat against possibly a democrat and a republican. of course, independent senate bids are uphill fights if you don't have support from one party or the other. and as i mentioned, kyrsten sinema, her popularity in arizona across the board is pretty low. but maybe she thinks now that she's

giving voice to independents in the united states. she says she's railing against the partisan broken system in washington, dc. there's a growing number of independents in arizona and across the country. and this is a position perhaps to give her a political future going forward. our thanks to anthony zurcher there. the british government has announced a major overhaul of the financial services industry, relaxing some of the safeguards imposed after the 2008 financial crisis. the chancellor, jeremy hunt, says the reforms will cut red tape and boost growth, but critics say his plan risk forgetting the lessons of the past. our business editor simonjack reports. october 1986, the so—called big bang, widespread financial deregulation in the uk, which ushered in an era of buccaneering, risk—taking freewheeling. but in 2008, the wheels spectacularly came off, banks around the world went bust, requiring tens of billions of taxpayer—funded rescues. tough rules to stop that

happening again are now being reviewed or binned. the banks have become much healthier financially since 2008, we've put in place a process so that financial issues can be resolved which we didn't have before, but on that basis, we also want to make sure that they can compete with other financial centres, whether it's the united states or asia. among 30 reforms announced today were plans to reconsider which banks really need to separate or ring—fence their retail operations from their riskier investment divisions, review rules on approving or punishing individual senior executives which have delayed or scared off hires from abroad, and these reforms come on top of measures already announced to scrap an eu—wide cap on bankers' bonuses and allow pension funds to invest more in long—term, harder to sell and therefore riskier assets to help fund the government's levelling—up projects. global banking chiefs said the uk needed to move with the times to compete

with other financial centres. london should not in any way take for granted its kind of preeminence and its dominance, so, any reform that is pro—growth, which looks at a vision for financial services overall and which makes the uk competitive is very timely and very important. financial services make up 10% of the entire uk economy, it generates enough tax to pay for two thirds of the nhs, it is an economic powerhouse. but as we found out 15 years ago, it can also be a financial wrecking ball. now, the banks here are much stronger than they were on the eve of that financial crisis, but there are many who think that rolling back regulation to boost growth is not without risk. in fact, some argue it's precisely because financial services are so important to the uk that it needs tough regulation. we cannot afford another gamble with financial deregulation

because what will happen is that if it goes wrong, the city will still walk away with its profits and its bonuses, but yet again, it will be ordinary people and ordinary taxpayers who will have to pay the price. both the city and the government are convinced that not changing is the biggest risk to future growth of all. simon jack, bbc news. international researchers have warned that dugongs, the aquatic mammals also known as sea cows, are on the brink of extinction. the international union for conversation of nature says the creatures are threatened by the loss of sea grass on which they graze, as well as the danger of being caught up in fishing nets or struck by boat propellers. scientists have also sounded alarm over the loss of other marine creatures, including exotic coral and shellfish. for more, let's speak to professor amanda vincent from the university of british columbia. professor, we know of course about the coming terms of our oceans, the pollution, the plastic pollution we see in them, but i mention these

seagrass that the specific animals feed on. what is it about that that puts them in such danger? i feed on. what is it about that that puts them in such danger?- feed on. what is it about that that puts them in such danger? i think we need to be very _ puts them in such danger? i think we need to be very aware _ puts them in such danger? i think we need to be very aware that _ puts them in such danger? i think we need to be very aware that while - need to be very aware that while plastics and pollution are definitely a concern of the ocean and something we must take seriously, the biggest single threat to marine biodiversity is nonselective, poorly regulated fishing, so we need to get our fishing, so we need to get our fishing practices under control if we are to have healthy oceans, and climate change of course is a major concern as well. and the story of dugongs really captures these two big threats. dugongs is a global species, found in the indo—pacific, are vulnerable to extinction and we have known that, but the new evidence shows that some of the fragmented populations around the new pacific are actually now in terrible state. so we have the population of east africa, critically endangered, and we have a population in new caledonia that is

endangered. those are specific populations that warn us that the species as a whole is very, very vulnerable, and so if we look for example in east africa, we find that it is primarily nonselective fishing gear that is putting the biggest pressure on the dugongs. so that would be nets that are catching the dugongs inadvertently, or if we look at the dugongs in new caledonia, we find the biggest pressure is poaching and extraction. so while we all talk about pollution and plastics, we need to be very mindful that it is poorly managed fishing that it is poorly managed fishing thatis that it is poorly managed fishing that is really causing the greatest concern. and i would also mention climate change. climate change, as you raised, is playing out with respect to the seagrass particularly. seagrass beds are the only flowering plants in the ocean and quite magnificent, and they are really suffering enormous lee under climate change, so you get a degradation of those habitats

through climate change and also of course through things like bottom troll fishing gear, which scrape the bottom, gouging everything and destroying these c beds as well. fix, destroying these c beds as well. a number of the factors there, how do you work in order to stop this from happening, raising awareness of course, but it is a big ask in terms of stopping that kind of fishing? there is tremendous concern about the fishing gear. by that, we mean fishing here that does not particularly catch anyone species but rather gathers everything that comes near it or that it chases down, indicates of bottom trolls. so we're going have to have better regulation of nonselective fishing gear, fishing gear that catches a great number of species inadvertently, and their moves towards making those changes. often we have reasonable policies, but the problem is implementation, the problem is implementation, the problem is implementation, the problem is actually having the public and political will to make

the difference. one thing that could help a lot is protected areas. so these are, if you will, marine parks. these are areas in the ocean where we restrict certain activities and particularly where we try to restrict fisheries that are causing tremendous troubles. would you have protected areas now in quite a number of parts of the world, but they're not necessarily well implemented and well enforced. right now, in montreal, there is a meeting for the convention on biological diversity, we are trying to set new targets, and included in there is a consideration of trying to protect 30% of the ocean by 2013. so that is something that would make a massive difference, both to restricting some fishing activities but also to giving an insurance policy against the crazy experiments we're running with the ocean right now.— with the ocean right now. professor vincent, thank _ with the ocean right now. professor vincent, thank you _ with the ocean right now. professor vincent, thank you so _ with the ocean right now. professor vincent, thank you so much - with the ocean right now. professor vincent, thank you so much for - vincent, thank you so much for bringing our attention to this, because when you think about the

dugongs, they are more commonly named the sea cows of these creatures, believed to be the thought behind mermaids, it would be a desperate shame to see them go. thank you so much forjoining us. thank you so much forjoining us. thank you so much forjoining us. thank you for watching bbc news. hello there. it does look like this cold spell is here to stay for the foreseeable future. we're likely to see further spells of rain, sleet and snow. some significant accumulations, i think, towards the second part of the weekend in one or two areas. and we'll start to see increasing amounts of freezing fog developing as the winds will turn light and particularly across england and wales. bitterly cold start to the weekend, then, as you can see from these temperatures. even lower in a few spots, maybe down to —9 celsius in places. and watch out for ice first thing around northern and western coastal areas. and it's here where we're likely to see the wintry showers continuing throughout the day today. elsewhere, there will be a lot

of wintry sunshine around, but we could see this area of snow becoming heavier, more persistent across the northeast and then the east of scotland through the day. some significant accumulations of snow here, certainly over the grampians. temperatures range from freezing to around 11—5 degrees, so another very cold day to come in. temperatures below par for the time of year. through saturday night, it stays icy. northern and western areas, where we've had the showers, this area of snow continues. it drift southwards a little bit into southern scotland, particularly in towards the borders, perhaps into the very far north, northeast of england, too. and again, a widespread sharp frost across the uk. perhaps temperatures down to around —7 or —8 degrees in a few places. now into sunday, we need to keep an eye on this weak area of low pressure, this weather front developing towards the southeast quadrant of england. that could develop thicker cloud and even some sleet and snow, particularly later in the day, which could affect parts of the southeast and east anglia. but elsewhere, it's another bright day, i think, on sunday. however, areas that start with some freezing fog could stay quite grey and very cold through the day, parts of east wales, the midlands and the east and england.

so no higher than freezing here. elsewhere, 1—4 degrees. for sunday evening and sunday night, we could see that area of sleet and snow affect the southeast. could see some significant accumulations, for example, in the south downs. so there could be some disruption in places for monday morning across the southeast. you need to stay tuned to the forecast, as this might change. elsewhere, it's largely clear, another very cold night to come with wintry showers around coastal areas. and you can see the upcoming week, it's remaining cold. all areas will stay very cold, with temperatures below the seasonal norm.
