subway shooting, bringing to an end a major manhunt. welcome to our viewers on pbs in america and around the globe. it's day 50 of the war in ukraine. russian gains remain limited as they continue to batter the strategically important city of mariupol in southeastern ukraine. it's been under siege for weeks and now russia claims more than 1,000 ukrainian troops have surrendered. but kyiv says the port city is still in its control. if mariupol fell into russian hands, it would create a land bridge between crimea — which russia illegally annexed in 2014 — and areas held by russian—led separatists in the donbas region. more russian troops could be deployed to the east, for a new offensive already planned there. in the battle for mariupol, its mayor says around 21,000 civilians have been killed, and 120,000 remain trapped, in appalling conditions. 0ur correspondent tom bateman reports now from the city of zaporizhia, where some people displaced from mariupol have ended up. a warning, his report contains upsetting images. this is a city reduced to darkness and death. russia's troops now occupy the theatre that was bombed as hundreds sheltered. their six—week siege of mariupol has brought it to the brink of falling. state tv in moscow showed these unverified pictures, claiming they are ukrainian soldiers surrendering. but the city's defenders posted their own videos, holed up in the port and a factory, still fighting, but their position seems desperate. "we won't give up," says this marine, "but we're encircled "with no resupply of ammunition or food." 100 miles north, just over the russian line, europe's 21st—century war is fought amid mud and rage in the trenches. mariupol�*s capture could see a push north, here. if mariupol falls, what will happen here? translation: well, we won't let this place turn into mariupol. - they're holding on. vitali shows me their soviet—era launchers. they also have brand—new western weapons but they want more, with the war about to move to a decisive phase. they're completely dug in here, as you can see. and the russians are that way. about 11—5 miles from here, within artillery range. and you can see they're ready for a long and grinding fight. they've been entrenched for 45 days. translation: we are on our own soil. - we expect them, to bury as many of them as possible. the more troops they send our way, the more fertile our land gets. russia's siege has killed thousands of civilians in mariupol and unleashed an appalling struggle for survival for the residents that remain. and these are the children of president putin's war. this hospital, north of the front line, is taking patients from mariupol and, like those in this ward, from elsewhere in the south and east. the doctors tell me they're treating children with injuries they usually see in soldiers, straight from the battlefield. for mariupol�*s survivors, whole lives are packed into a few bags. and they carry the fresh horrors of this war. lena and timothy are homeless. their apartment block obliterated in an air strike. ukraine's leaders call mariupol the "heart of their war effort," but they fear soon it could stop beating. tom bateman, bbc news, zaporizhzhia, in south—east ukraine. russian state media are reporting that the most important ship in russia's black sea fleet, the moskva missile cruiser, has been badly damaged after ammunition on board blew up, causing a fire. quoting the russian defence ministry, interfax says the crew had all been evacuated and the cause of the fire was being investigated. earlier, a ukrainian official said the ship had been hit by two missiles but this has not been confirmed. the moskya gained notoriety early in the war when ukrainian border guards defending an island refused its demand for their surrender. president biden has announced an additional $800 million in military assistance to ukraine. the package includes artillery systems, rounds and armoured personnel carriers. the news came shortly after mr biden spoke to ukraine's president volodymyr zelensky. to ukraine's president volodymyr zelensky. meanwhile, president biden says the evidence appears to suggest that russia is committing genocide in ukraine. he says it's becoming "clearer and clearer" that vladimir putin wants to "wipe out the idea of even being ukrainian." over the past two weeks, russian forces have been withdrawing from the north around the capital, after failing to enter kyiv. their retreat from the areas — shown here in purple — has allowed a clearer picture to emerge, of the terrible damage and destruction left in their wake. 0ur correspondent mark lowen has visited the towns of bucha and borodyanka, travelling with those trying to document evidence of war crimes committed by russian troops. his report contains upsetting details. ten more — the numbers, the mass graves, the contempt for life. some so badly charred, they're just the pieces for ukraine to pick up. the man and the inhuman. what happened here in bucha and elsewhere are notjust sins, says ukraine, but war crimes. french investigators and other international teams are helping prepare a lawsuit against russia. ukraine's prosecutor general says they've already opened more than 6,000 cases. a lot of people speak about genocide of ukrainian people, and actually, they have all grounds to speak about genocide. vladimir putin himself, he is president of aggressor. do you believe you will ever see him judged in an international war crimes court? it is very important, actually. it's very important to the whole world to stop dictators. the challenge for prosecutors will be to establish a line of command, from the grave to the top of the russian state, to show that crimes were not just committed, but ordered. perhaps that will help give ukrainians a sense of accountability, and that from such suffering can comejustice. the long road to that goal, past a landscape of horror, is led notjust by the state, but by volunteer investigators, a grassroots army fighting for the truth. they come to borodyanka, gutted from the air in a relentless assault tearing out its heart. amidst the ruins, banned cluster bombs. the destroyed ground is fertile for the team building their case. we're trying to tell the world the truth, and we are trying not to let russia formulate their lying narratives about the war in ukraine. we are trying to show to people that those war crimes which russian troops are committing became, like, a pattern of their behaviour. among the shattered sea of victims are 0xana and her husband, nikola. they escaped — their apartment didn't. with the need to tell this story comes the duty to collect it. translation: our home was our cosy nest. - we were planning our children's birthday here. my mother got outjust before the strike. it's hard to describe our terror. it's more like hate. it's very important to say what happened because these are notjust war crimes. russia will not stop until it destroys our country. freedom and safety, what ukrainians held dear, has been destroyed. their solace now would be punishment for those who have broken this country. mark lowen, bbc news, borodyanka. as russian troops withdraw from towns and cities in western ukraine, women are speaking out about the rape and torture they were subjected to by putin's soldiers. on wednesday, nobel laureate and human rights activist, nadia murad, who was kidnapped, tortured and raped by islamic state in 2017, launched new global guidelines detailing how to collect evidence from survivors and witnesses of conflict rape and had this appeal. if women who have suffered such immense loss and incredible pain can find the strength to not only rebuild our lives but help our families, not only rebuild our lives but help ourfamilies, communities help our families, communities and help ourfamilies, communities and entire countries, surely the rest of the world can find the rest of the world can find the strength to take meaningful steps two and sexual violence in countries. lauren wolfe is a journalist and professor who has reported on conflict rape all over the world for more than a decade and she joins me from seattle. i wanted to begin by asking you how unique this real—time reporting of rape used as a welcome in ukraine, which we have been charting on the bbc and many organisations have been, and how that helps? how unique that the reason real—time reporting of breaks? —— there is. real-time reporting of breaks? -- there is-_ -- there is. the unique opportunity _ -- there is. the unique opportunity we - -- there is. the unique opportunity we have i -- there is. the unique i opportunity we have right -- there is. the unique - opportunity we have right now in ukraine is that, until this last month, it is a functioning system, internet, judiciary is, doctor is, the right institutions in place and that is really different from say rwanda during the genocide, syria just being armed to bed. it is different and getting the word out requires technology and self reporting. there are groups working with women, taking testimony and they are coming up. taking testimony and they are coming um— coming up. does that help combat the _ coming up. does that help combat the crime?

if there will be prosecutors, which - combat the crime? if there will be prosecutors, which i'm - be prosecutors, which i'm willing to bet there will be but it is a complicated subject. you need to document rape and assault in a specific way, so if the earlier the better when peoples memories are fresh. we cannot always see signs of rape but the right physical signs such as cigarette burns, things like that. but more than that, it is what women and sometimes a man remember hearing so if they don't make it sarah, i can't remember what the phrase was but the men who were raping women kept saying, you want your country, this is for your country. something like that. so those kind of patterns when they can be predicted can be prosecuted. we can see who is ordering them. also paper trail. in germany, during the war, for example.— trail. in germany, during the war, for example. dikili nasty as - ect war, for example. dikili nasty weed is _ war, for example. dikili nasty weed is the _ war, for example. dikili nasty aspect is the strategic - war, for example. dikili nasty | aspect is the strategic reasons used for rape. — — eight particularly. do you think it is premeditated and large scale from what you have been hearing?— from what you have been hearin: ?

first of earlierfunds like this? first of all, i would like to commiserate with the victims of this flood, for the loss of life, loss of property, and i want to see the impact of this flood will last for a very long time, especially considering that we are just recovering from the pandemic, covid, two years of lockdown. in many respects, we have been working in the climate space, we not surprised, because the climate predictions clearly that extreme events like flooding and flooding over time is basically — the intensity is going to increase. if you look at durban for example, we have had a similar instance in 2018, 2019, and now increasingly the intensity of the rainfall — in some respects it is not surprising that it has been so devastating.— devastating. that's right, we look at the — devastating. that's right, we look at the region _ devastating. that's right, we look at the region - - devastating. that's right, we look at the region - three . look at the region — three cyclones, two tropical storms, it covered madagascar, malawi, is that what south africa's worry is due to climate change, heavy rainfall?

absolutely, most south africans do have some level of climate change, and so on, but those plans haven't been translated into a specific, you know, a strategy that could be implemented within budget and so on. so what happens is that in maintaining infrastructure like stormwater drain systems, they are not maintained, so when an incident that happens like what we have seen... dr mao amis, executive director for the african centre for a green economy. thank you for being with us.— here in the uk, the conservative peer lord wolfson has resigned from the government as a justice minister over covid law—breaking in downing street. prime minister borisjohnson was fined for attending a party at number 10 during lockdown. mrjohnson said he was sorry to receive lord wolfson's resignation. police in new york have arrested a suspect wanted in a shooting at a subway station in the district of brooklyn on tuesday after receving a tip off to his whereabouts. ten people were injured when the gunman fired 33 rounds from a semi—automatic handgun. the suspect, frankjames, has a criminal record and was apparently known to the authorities. the bbc�*s tim allman reports. this was the moment that 62—year—old frankjames was 62—year—old frank james was taken 62—year—old frankjames was taken into custody. picked up ijy taken into custody. picked up by officers in manhattan's east village after a tipoff at a nearby mcdonald's. share village after a tipoff at a nearby mcdonald's. are you ”lannin nearby mcdonald's. are you planning to _ nearby mcdonald's. are you planning to respond?

"there is no elation in our family today following the sentencing. 0ur amazing husband and father has been taken from us in an appalling and violent manner. nothing will ever compensate for that." the grief of a family and a community triggered a national debate, how open should mps be in an age of terrorism? today, a former mp and family friend said sir david was a man who loved to perform his public duty. i don't think david would have wanted this, in his name, to result in any undue distancing of mps from their constituents. he was a man who wanted to meet his constituents. sir david's family said it breaks their heart that he would have greeted the murderer with a smile, a killer who left court today knowing he will die injail. the manager of northern ireland's football team has been strongly criticised for his claim that female teams concede goals and clusters because they are more emotional than men. has comments came after a defeat to england that left his side unable to qualify for next year's women's world cup. it was supposed to be a night for making strides forward with the biggest crowd match in northern ireland. instead it was this claim that put him in the spotlight. when a team concede _ put him in the spotlight. when a team concede the _ put him in the spotlight. when a team concede the goal, - put him in the spotlight. when a team concede the goal, theyj a team concede the goal, they concede a second one within a very short period of time, because girls and women are more emotional than men, so they take a goal and they don't take that very
