welcome to our viewers on pbs in america and around the globe. it's already three days since the major eruption of an underwater volcano in tonga and still there is a very worrying lack of information about the scale of the damage done across the many tongan islands, or the whereabouts and well being of many of the islanders. these very limited pictures have just been sent to us. they are from one of the surveillance flights sent by australia and new zealand to assess the damage. the eruption itself appears to have taken out the one main underwater communications cable and there are suggestions that could take weeks to restore. a lot of ash on the ground. tonga has a population of around 100,000. the red cross estimates that about 80% of them may have been affected. 0ur correspondent rupert wingfield—hayes has the latest. these pictures of the hunga tonga—hunga ha'apai volcano erupting are from last friday. this is just a foretaste of what was to come a day later — an eruption many, many times larger. this is the volcano poking above the ocean's surface last week. and today, it is completely gone. it has now been confirmed the huge eruption severed the main cable linking tonga to the outside world. this morning, new zealand dispatched aircraft to try and find out what is going on. some of those islands are reporting that they haven't had loss of life, but i would reiterate that is second—hand and it is early days. this evening we learnt this british woman, angela glover, was killed by the tsunami that hit the island on saturday. she'd moved to tonga in 2015 to open an animal shelter. she died trying to rescue her dogs. the strange thing was the uglier the dog, the more she loved it. her initial call to go to tonga was to swim with whales, which she did, and, yeah... beautiful girl, she's irreplaceable. offers from new zealand and australia to help tonga are being complicated by the covid pandemic. the island nation is currently covid—free and it wants to stay that way. they have had disasters during the pandemic previously, from sort of cyclones and hurricanes, and what they did then wasjust air drop supplies in and there was no physical contact or interaction between, say, troops and the local forces. a century ago, nearly one in ten tongans died in the 1918 flu pandemic. any reluctance now to ask for help would not be without reason. rupert wingfield—hayes, bbc news, tokyo. well, earlier, ispoke tojoanne mataele who has been doing all she can to reach herfamily in tonga following the eruption. these are very anxious times indeed. she is in melbourne. i haven't been able to reach my family since 630 tonga time when the blackout happened. i have faith that they are well and saved. have faith that they are well and saved-— have faith that they are well and saved. ~ , . ., ., and saved. we share that faith with ou and saved. we share that faith with you and — and saved. we share that faith with you and hope _ and saved. we share that faith with you and hope that - and saved. we share that faith with you and hope that is - and saved. we share that faith with you and hope that is the l with you and hope that is the case. are you able to do anything?

there is widespread fear and sometimes loathing about the mess and the public�*s reaction. yet there's a pause before the official report from civil servant sue gray emerges. it is only right that we don't condemn the prime minister, someone who's apologised to parliament and said that he will come back when the sue gray investigation is finished. that is the fairest way of dealing with this. it's impossible to know right now how many mps really want borisjohnson out. but many have heard anger from constituents when, not if, is a common refrain. my constituents at the moment are about 60:1 against the prime minister, and i've listened very carefully to members of my association too. there are some very strident voices in my constituency demanding that i support the prime minister. for many conservatives, it's the style and character of this government that concerns, not the specifics of any parties. but acting to take out a leader is a drastic move, and it's not clear yet how many punches the prime minister can really withstand. laura kuenssberg, bbc news, westminster. stay with us on bbc news. still to come: where is my car. 0h, where is my car. oh, my god. where horsepower, of all kinds, is finding the going tough along north america's eastern seaboard. donald trump is now the 45th president of the united states. he was sworn in before several hundred thousand people on the steps of capitol hill in washington. it's going to be only america first. america first. demonstrators waiting for mike gatting and his rebel cricket team were attacked with tear gas and set upon by police dogs. anti—apartheid campaigners say they would carry on the protests throughout the tour. they called him the 'butcher of lyon'. klaus altmann is being held on a fraud charge in bolivia. the west germans want to extradite him for crimes committed in wartime france. there, he was the gestapo chief klaus barbie. millions came to bathe as - close as possible to this spot. a tide of humanity that's i believed by officials to have broken all records. this is bbc world news. the latest headlines: australia and new zealand's military send aid to tonga following the volcanic eruption and tsunami. america's airlines warn of catastrophic disruption to travel if 5g technology is rolled out near airports. the rabbi of a texas synagogue who was taken hostage on saturday has described how he threw a chair at the gunman in order to escape. the hostage—taker, named as british citizen malik faisal akram, was shot dead after a stand—off with police. two teenagers have been arrested in manchester as part of the investigation. our special correspondent ed thomas reports. what made malik faisal akram leave blackburn, the place he called home, to travel to texas, arm himself with a gun and hold people hostage inside a synagogue? there was a tense ten—hour stand—off. as an fbi swat team moved in, the 44—year—old spoke to his family back home. his words were recorded as he became increasingly desperate. these pictures show several hostages running for their lives. within minutes, malik faisal akram was shot dead. the rabbi here described their ordeal. it didn't look good, it didn't sound good. we were very... we were terrified. and when i saw an opportunity, where he wasn't in a good position, i made sure that the two gentlemen who were still with me, that they were ready to go, the exit wasn't too far away. i told them to go, i threw a chair at the gunman and i headed for the door. and all three of us were able to get out without even a shot being fired. throughout the stand—off, malik faisal akram was heard demanding the release of aafia siddiqui. she's known as 'lady al-qaeda', a pakistani neuroscientist jailed in the us for trying to kill american soldiers in afghanistan. it is the way that he was killed, he was shot. that shouldn't have happened. tariq hussain knew malik faisal akram and his family. he says many here question his mental state at the time he went to america. it's very frustrating for the family, they're going through a very hard and difficult time and our prayers are with them. if there was mental health issues, why did he go in the first place? the people looking after him, why did he fly out? there's questions that are not being answered, you see. this message was posted on blackburn muslim community facebook page, believed to be from malik faisal akram's brother, and has since been taken down. he apologises and says: and tonight, a second close family member of faisal malik akram, who didn't want to be filmed, raised concerns over his state of mind. he said it was widely known in blackburn that he was struggling with his mental health. the us president has described what happened here as an act of terror, while those who escaped said they felt lucky to be alive. ed thomas reporting there. we have a snowy toronto for you here. millions of people across america's east coast and canada's southeastern provinces are hunkered down as a powerful winter storm sweeps through major population hubs, disrupting travel and cutting power to thousands of homes. stephanie prentice reports. a national pastime taken to the streets. in canada, when life gives you ice, make an ice rink. this neighbourhood just outside toronto using a break in the snowstorms to enjoy their new project. it's a little bit bumpy, the trees are a little bit annoying sometimes but yeah. a little bit helpful though too. we started off with two houses, we've expanded to three now. we make it a little difficult for the mail carrier, i know that. they gotta walk around the rink. the mailman may be getting through but for many the snow knocking out their usual forms of transportation. where the bleep is my car, oh my god. for others, an opportunity to try more traditional ways of getting around. it's getting heavier. but not everyone is a jump away from trying to have a good day across the snow ravaged south—eastern provinces, with extreme weather warnings in place across ontario and quebec. power outages for thousands of homes, offices and schools closed and visibility at near zero in some areas. the streets are packed. the streetcar is barely moving. everything is covered with snow. never seen anything like this. over in the us, things are starting to improve, with the national weather service saying that although snowfall will continue, the storm will start to slowly wind down into tuesday. a state canadians can only anticipate. but for some, being stuck at home isn't the worst thing. stephanie prentice, bbc news. it's a question that has plagued historians ever since the end of the second world war. who betrayed the family of anne frank to the nazis? anne frank died in a concentration camp in191t5, at the age of 15, after two years in hiding in amsterdam. her diary, published after her death, is probably the most famous first—hand account ofjewish life during the war. anna holligan reports from amsterdam on the conclusion of a lengthy investigation. the final entry in anne frank's diary. tuesday 1st august 191m. three days later, thejewish teenager was arrested. this was the frank family's hiding place during the nazi occupation of the netherlands. and this question of who betrayed the frank family, who had lived in this building undetected before the end of the war, has remained one of the great mysteries of dutch history. and now this team of investigators have identified a man who they believe is the key suspect, a jewish lawyer who had been based here in amsterdam helping jewish refugees fleeing nazi germany. no dna clues or video images existed, so the detectives relied on circumstantial evidence, and a note. the final suspect became the person who was named in an anonymous note sent to 0tto frank shortly after he got back from the camp, auschwitz, in which a man called van den bergh was identified as the betrayer. 0tto frank was anne's father and the only member of the family to survive the war. the suggestion that the betrayer appears to be someone from within thejewish community is hard for many to bear. the historic context is critical here. it's a story of a man who was cornered and in order to save himself, his wife, his children from the gas chambers he gave a list of addresses to the sd which had no names. so the story is tragic. while there is still a degree of scepticism that we may never know the true identity of the betrayer, this tale serves as a warning, a lesson of what humanity may be capable of in its darkest time. yet another way anne frank's legacy remains alive. anna holligan, bbc news, amsterdam. a key figure in uncovering these findings is vince pankoke, a retired fbi special agent and director of investigation of the cold case team which looked into the story of anne frank's betrayal. earlier, iasked him how conclusive he believes his evidence is. i know it has been a frustration of historians and even people who have followed anne frank for years and years because there has never been a clear answer. we feel that we have identified the most likely cause of the raid. we are 85%—95% sure. for a case this old, nearly 80 years old — that is pretty conclusive. what was his role in the community at the time? where did he fit in the panorama of amsterdam at the time? of course arnold van den bergh was jewish so he was subject to many of the restrictions ofjews that the nazis occupiers put on but because he was a member of the jewish council he received a benefit, an exemption from deportation at first but he even took further action to try and ensure his safety and that of his family by purchasing another type of exemption that existed during this time, it was called 120,000 stamp, and that would further exempt him from deportation and then finally, as a final move in his chess game to protect himself and family, he applied for and received a status that they called calmeyer status and that was a nazi office that was established that you would apply to and claim that either one or more of your grandparents were not in factjewish and then therefore you would not be jewish. he actually received this exemption in september of191t3, declaring him non—jewish. there are so many questions i want to ask you and we are right up on the clock, unfortunately. let me ask you this, you've got the book behind you, the betrayal of anne frank — is that word "betrayal" the right word, do you think? well, only if it is put into context. to understand that arnold van den bergh, like so many otherjewish people during this time period, were forced into collaboration by the nazi occupiers. that is the betrayal of anne frank. the latest attempt to work out just who frank. the latest attempt to work outjust who did. that is bbc news. hello. clear skies across most parts of the uk at the moment. may mean we're getting to see a full glimpse of the first full moon of the season, the wolf moon, but it also has led to temperatures dropping quite widely. a widely frosty start to tuesday morning, maybe as low as —3 to —5 in some parts of central, southern england, and it's here where we've got some dense patches of fog to start the tuesday morning commute. some of that could start to build for a while during the morning rush—hour but then slowly start to shift during the morning. lots of sunshine elsewhere. a bit more breeze to the north and west, so not as cold here, but it's here in northern ireland and western scotland we'll see some outbreaks of rain develop from lunchtime into the afternoon. most parts, though, will stay dry. cloud amounts increase. predominantly sunny, though, for northern england. and with winds lightest towards the south and east of the country, here, we'll see temperatures actually the lowest after that foggy start — only three to five celsius for one or two. the milder breeze out in the west lifts temperatures between 9 and 11 celsius. into this evening, some showers for a time in scotland and then another batch will push in on strengthening winds, all tied into this cold front. this is a bit more active than the one that precedes it, just bringing a few showers across england and wales during the night, meaning not as cold a start to wednesday morning. but cold air will be pushing southwards through the day behind this zone of cloud and showers which starts around the borders of scotland, northern england, north wales and then drifts its way southwards. in its wake, though, most will see good long sunny spells through the afternoon. one or two showers dotted around to the north and northwest, those showers turning wintry in northern scotland — just 2 degrees in lerwick, holding onto around 10 celsius in the south. but as we go through into wednesday night and thursday morning, a widespread frost will develop once again. perhaps for some of you, a colder night than will start tuesday. and that frost will be greeted with some sunshine overhead too. but a cold breeze down eastern coasts could feed in one or two wintry showers for a time. a noticeable wind—chill here. maybe feeling subzero through the day across some eastern coastal counties of england. come further west, with the winds lighter, temperatures up to where we should be for this stage in january. another chilly night to come, then, through thursday night into friday, and as the high—pressure starts to drift its way southwards once again, we are back to the problems with mist and fog in the south, but allowing more of an atlantic breeze to push in through the north, bringing varying amounts of cloud and lifting the temperature a little bit. and, crucially, for much of the uk, end of the week and the weekend will be staying dry. see you soon. this is bbc news, the headlines: the united nations says there's been a distress signal from the tonga archipelago following saturday's massive volcanic eruption and tsunami. there is a worrying lack of information about the scale of the damage and the whereabouts and well—being of many of the pacific islanders. australian and new zealand military ascending humanitarian aid. america's largest airlines have warned of a catastrophic disruption to travel if telecommunications firms roll out their 5g technology without limiting its scope near us airports — because it might interfere with altitude devices. they're requesting it be delayed until the necessary upgrades have been made to aviation equipment. boris johnson's borisjohnson�*s former chief adviser dominic cummins has said he warned the prime minister in person about holding a drinks party during the first lockdown in may 2020. downing street denies that. now on bbc news, it's time for hardtalk.
