this is bbc news. our top stories: two presidents, two versions of history. the leaders of america and russia clash over the conflict in ukraine. translation: to defend our historical lands and liquidate | the threat of the neo—nazi regime, we launched a special operation. we are seeing again today what the people of poland and across europe saw for decades, appetites of the autocrat cannot be appeased. born in the rubble — the baby who lost her entire family in the deadly turkish earthquake, who now has new hope. the us supreme court is to hear arguments from people claiming that internet providers

could be enabling terrorists. and nearly 60 years after his death, the family of malcolm x say they're going to sue the cia and fbi. welcome to our viewers on pbs in america and around the globe. presidents putin and biden have given their competing views of the war in ukraine. president biden, who was in ukraine's capital kyiv on monday, has made a major speech in poland where he said the west's support for ukraine "will not waiver". in his state of the nation address vladimir putin defended his full—scale invasion, blaming the west for provoking the war, and he announced he's suspending russian participation in the major nuclear arms control

agreement with the us. here's our russia editor, steve rosenberg. the world according to vladimir putin feels like a parallel universe. who started the war in ukraine? "not russia," he says. translation: responsibility for fuelling the ukrainian - conflict, for its escalation, and for the growing number of victims lies fully with the west and, of course, with the regime in kyiv. i wish to repeat, they started the war, we are using force to stop it. but it was russia that invaded ukraine. western military aid has helped kyiv resist. it hasn't forced the kremlin, though, to de—escalate. today, president putin suspended russia's participation in the last—remaining nuclear arms control treaty with america —

an agreement that limits nuclear arsenals and provides for missile inspections. no longer topical, says the kremlin. translation: we know that the west _ has directly helped kyiv to launch strikes on airbases where our strategic nuclear bombers are located. now they want to carry out inspections of our military sites. in light of today's confrontation, that is absurd. applause support here, but unpicking that treaty risks a nuclear arms race. in order to avoid nuclear war, it's better to have a framework, but losing this framework, we are witnessing the real threat of a nuclear war. washington says the kremlin�*s decision to halt participation in the nuclear treaty is deeply unfortunate and irresponsible. the bbc wasn't allowed to attend the kremlin leader's big speech.

journalists from what russia calls "unfriendly countries" were not sent an invitation. but after watching president putin on tv, this is what struck me most about him. his "special military operation" has not gone at all according to plan, but regret, there was no hint of that, and no sign at all that putin is looking foran off ramp. instead of compromise, he favours confrontation. applause and this audience loved it. mind you, the president here was preaching to the converted. all main russian tv channels carried the speech live. from these images alone, you'd never know things had gone badly wrong for russia on the battlefield. translation: russia will respond _ to any challenge we face, because we are one country, one people. we believe in ourselves, in our strength. truth is on our side.

after one year of war, the kremlin is still managing to persuade most russians to believe that. steve rosenberg, bbc news, moscow. the us has rejected president putin's claims as absurd. president biden delivered his own speech in poland, where he described the war as a battle for democracy. our north america editor, sarah smith, has been travelling with the president and reports now from warsaw. in front of the blue and yellow ukrainian colours, president biden came here to project american might and to pledge to use it to protect ukraine, democracy and freedom. when russia invaded, it wasn't just ukraine being tested, the whole world faced a test for the ages.

europe was being tested, america was being tested, nato was being tested, all democracies are being tested and the questions we faced were as simple as they were profound. would we respond or would we look the other way? we know the answer, we did respond, we would be strong, we would be united, and the world would not look the other way. and ukraine — ukraine will never be a victory for russia. never. cheering this is a direct appeal to nato allies, as well as to the america people, to keep up their commitment to ukraine, even if this conflict could last for years to come. refuting vladimir putin's assertion that the us provoked this war, he spoke directly to the russian people. the united states and the nations of europe do not seek to control or destroy russia.

the west was not plotting to attack russia, as putin said today. and millions of russian citizens, who only want to live in peace with their neighbours, are not the enemy. band plays star spangled banner earlier today, mr biden met polish president andrzej duda. this display of solidarity is to demonstrate america's guarantee of poland's security and its promise to defend every inch of nato territory. but they want more than that. poland backs ukraine's demands for f—16fighterjets. the us is not ready to send planes yet, but that could change. and we will keep standing up for these same things, no matter what. with public support for the war slipping in america, the president made a direct appeal to americans' fundamental values and the need to fight for them. freedom. stand with us. we will stand with you.

let us move forward with faith and conviction and an abiding commitment to be allies, not of darkness, but of light. not of oppression, but of liberation. not of captivity but, yes, of freedom. may god bless you all, may god protect our troops, and may god bless the heroes of ukraine. proud that mr putin's expectations of a weak and divided west have been met with a firm, united front against his war, president biden�*s biggest task now is trying to keep his allies as committed as he is, for as long as it takes. sarah smith, bbc news, warsaw. well, earlier i spoke to michael o'hanlon who's a senior fellow and director of research in foreign policy at the brookings institution. i began by asking what he made of president biden�*s speech in warsaw. the most important thing of all is that president biden

took the trip and that he thinks this conflict in ukraine, this terrible tragedy, is at the top of his agenda as he enters his third year of presidency. that may or may not be enough to impress vladimir putin. it may or may not be enough to impress all the republicans in congress but it is a firm statement of resolve and resoluteness of the commander—in—chief of the united states and i think vladimir putin has to again be surprised and chastened that the western world has held together so well, for so long. it doesn't tell us when the war will end or a strategy, but an impressive statement that the white house is not losing faith. president biden spoke about american commitment to ukraine as well as offering half a billion us dollars more in military aid. do you think nato and the us will budge and provide the necessary weaponry that president zelensky is asking for? two things on that.

first of all, we have now provided ukraine, collectively, europe, united states and elsewhere, $100 billion and more in assistance, striking and unprecedented and almost approaching marshall plan—like levels, all in one year to one country, that's impressive and important. on the one hand, it does not necessarily guarantee that ukraine will win back the i7% of territory that russia still holds and even if we were, like britain, to intensify and increase the transfer of tanks to provide longer range missiles, it does not really tell you how the battlefield dynamics may go as there are just too many uncertainties. i think we are in for a long, tough 2023 of additional fighting with no possibility of any peace process until summer because both sides have their theories on victory that they want to try out. president zelensky hopes that the support of the west,

visits by presidents like president biden and increase weaponry and tanks and fighterjets from britain, all of that, all of that will ultimately result in war—winning capability. president putin will hope that we will lose faith and resolve. unless each side tries out that theory, i'm afraid this war will continue. president putin has accused the west of provoking and starting the war and says he will suspend the nuclear arms agreement. how significant will that be? it is not trivial. he is reminding us there are big stakes in the broader relationship between russia and the west and avoiding nuclear war are at the top of the list. in that sense, he's always playing the nuclear option when he brings this up. on the other hand, it is not as if the west is losing faith. it is not as if we are giving into his bluster, we've heard it before and stood up to it before. his whole theory that we started this war,

you know, what i'm trying to figure out, is does he know he is lying when he says it or half believe it? he does believe the western world has encroached on the former russian and soviet space and now we're trying to steal away ukraine into western orbit when it has been historically inherent who and what russia is. that part he probably believes. however he is not foolish enough to believe that we started the war or that president zelensky is a nazi, he is not that dumb. that is the rhetoric part and he is not fooling his own people. ijust hope that some russians will start figuring that out. let's get some of the day's other news. a new york court has found mexico's former security chief guilty of taking bribes in return for allowing safe passage for drugs. prosecutors said genaro garcia luna was secretly taking millions from the country's biggest crime group, the sinaloa drug cartel, the same one he was supposed to be pursuing. luna faces ten years to life in prison. a train operator has been

ordered to fund the entire cost of cleaning up contamination after one of its freight trains derailed earlier this month. the accident caused hundreds of tonnes of chemicals to be spilt in east palestine, ohio. now the head of the environmental protection agency says norfolk southern would bear the cost for the trauma it inflicted on the town. rescuers in southeastern brazil are scrambling to find dozens of people still missing, after record rainfalls caused flooding and mudslides. 46 people have been killed. almost 70 centimetres of rain fell in 2a hours around the popular beach city of sao sebastiao, more than double what would be expected in a whole month. emergency teams in southern turkey have been carrying out more searches of the rubble after another earthquake on monday, just two weeks after two massive quakes devastated the region. buildings weakened by those first tremors finally collapsed. the 6.3 magnitude quake struck near the turkish city

of anta kya, close to the border with syria. our correspondent, anna foster, sent this report. there seems no end to the agony. today, fresh images of loss and grief. millions of people, desperately trying to heal, have been traumatised again. for many, the first thought was protecting their families. they gathered up everything that was precious to them and ran. this volleyball court was set up as a relief centre after the first earthquake, and by yesterday, it was almost deserted. but when people felt the ground shake under their feet again last night, they fled back here, looking for a place of safety. felice and her sister are homeless now. holding her nephews tight, she doesn't know what's next. translation: i'm - concerned for our future. i'm afraid for our children. i don't want them to be orphans.

mentally, i'm upside down. i hope good things will happen. we're in a miserable situation, running here and there, with so little belongings with us. in north—west syria, afraa has already lost her parents and sisters. she was born in the rubble, as her mother died, rescuers cutting the umbilical cord. thousands of people offered to give her a new home. now her aunt and uncle have adopted her, to raise alongside their own baby daughter. translation: she will lack for nothings. . . .. l i'll never spare a penny raising her. she's as dear to me as my children are. even more. cousins, now sisters. a final memory of the lost mother whose name she now bears. anna foster, bbc news, adana. stay with us on bbc world news, still to come:

sonia gipson—rankin is an associate professor of law at the university of new mexico school of law. she nowjoins us live. sonia, thank you forjoining us. now, how significance is this case? , , . , case? this is a very significant - case? this is a very significant case. - case? this is a very - significant case. section 230 has a statute that is under discussion here, known as the 26 words that created the internet. every platform we have to day, every conversation that happens online, every purchase that happens online, every dialogue and discussion and sharing of information is based off of the statute, so this is the first time the united states supreme court has brought forward any kind of or listen to any cases referring to the statute.— to the statute. you have mentioned _ to the statute. you have mentioned this - to the statute. you have mentioned this section, | to the statute. you have - mentioned this section, 230, thatis

mentioned this section, 230, that is almost around 27 years old, what is the significance of the time and what is the difference now with what is going on with these cases? section 230 was established in response to content moderation concerns. there was a platform and message board — it is almost funny to remember the beginning of message boards on the internet but there was this idea that platform should be held responsible for any defamation that occurred by any persons sharing information that was false about another online. in response, congress grew very concerned that this could stifle this burgeoning idea of what the internet is and came up with the idea of section 230. section 230 at that time or has two major provisions, one will shield content providers from liability, but it also has a sword provision which allows

providers to model and determine what is permitted on their platforms. this happened decades from where we are today with what technology was dogmatic now, briefly, what has the response ben white with efforts trying to reform this section 230? i think there is a reason we are 27 years in and no change has happened. i think because this is a statute that has to go through congress it often gets stopped for a number of different reasons but i think we are at a different point in the united states right now. there are members from progressive spaces that are concerned that it is shielding too many providers from very harmful behaviour online, but at the same time there are those of conservative names that say it is purposefully locking dialogue and conversation online. this is a pretty weighted conversation in court right now. sonia gipson—rankin, thank you very much for your time.

thank you. it is 58 years since the civil—rights campaigner malcolm x was shot dead in the city of new york. now his daughter is suing the police, the fbi and the cia, saying they covered up evidence regarding his death. the family are seeking $100 million in damages. the bbc�*s tim allman reports. he was an iconic figure, in black america's struggle for civil rights. his death, a shocking moment in a decade marked by political violence. there have long been questions about the murder of malcolm x. now at the very place where he was killed his daughter says she wants answers. for years, ourfamily has fought for the truth to come to light concerning his murder, and we would like our father to receive the justice that he deserves. this man, thomas hagan, was convicted of killing malcolm x, along with two other men who were later acquitted. black people should realise

that freedom is something that they have when they are born. the family of malcolm x accuses various government bodies, including the fbi and cia, of failing to prevent his wrongful death. it's also claimed they concealed evidence that would have cleared the two men that were wrongly convicted of his murder. and so for this great injustice, we will be filing a wrongful death lawsuit against these governmental entities for $100 million. the new york police department says it won't comment on pending legal action, and there has been no word from the fbi or cia. for nearly 60 years, the death of malcolm x has been shrouded in mystery. his family hope this lawsuit may finally reveal the truth. tim allman, bbc news. mountain biking is helping to revive communities in australia beset by years of bushfires,

i'm @lmmisztak. hello there. we're seeing a change to cooler weather on wednesday, even with some rain around as well. now, it has been really dry for many central and eastern parts of england this month. we started the week with temperatures as high as 17 celsius. but things are changing because we've got this cloud that's moving up from northern france to bring some showers, and that's ahead of this thicker band of cloud that's bringing the rain on that weather front there. that's going to continue to push its way steadily eastwards, and then following on from that, this is where we get the cooler air coming in from the atlantic. and we start the day with temperatures around about 5—6 celsius with a lot of cloud around. we've got the rain across eastern scotland that will move away, sunshine and showers will follow wintry over the hills, perhaps, and a cool wind for northern ireland, sunshine and showers here.

more cloud for england and wales, could keep some rain across some northern and eastern parts of england, may well turn a bit brighter with some sunshine, but again, some showers for wales, the south west and later the midlands. and for all of us, it's a bit cooler, the temperatures typically around nine celsius or so. now we've got cooler weather because we're changing the wind direction. instead of that very mild south—westerly that we started the week with, it's more of a north westerly wind turning northerly across england and wales as we head into thursday. around the top of that area of high pressure, some weather fronts will bring some wetter, windy weather across the north, but we've still got some rain to clearfrom overnight across southern parts of england. that cloud could be very slow to break up, other parts of england, of wales seeing some sunshine, more cloud coming into scotland and northern ireland, wet and windy weather coming into the far north of scotland. temperatures could make double figures in scotland and northern ireland, but it's chilly 8—9 celsius for england and wales. that high pressure is not really dominating just yet. instead, we've got this weather front, an area of low pressure sliding down through

the north sea. now, there's not going to be much rain left on that weather front. it's a band of cloud, most of the rain dying out, we'll get a northerly wind following on behind, maybe a bit of sunshine coming back into scotland and some sunshine perhaps towards wales and the south west of england. probably quite a bit of cloud on friday, although it won't be quite as cold, those temperatures generally around 9—10 celsius. so we've got some wet weather around the middle part of the week, that's going to introduce something a little bit colder. but then with high pressure building through the rest of the month, looks like we're back into dry weather.
