they went on the rampage, shooting their way through the building... screaming. ..and into the auditorium. there was supposed to be a rock concert here. gunfire. instead, this. gunfire. the attackers walked through the stalls, firing indiscriminately. dozens of people are reported to have been killed. "they've set the hall on fire! "the hall's on fire," he says, as more shots ring out. then, the rush to escape. "there's panic! "panic," she says, as the crowds fled from the auditorium and tried to get out. soon, the whole building was ablaze. the mayor of moscow said it was a terrible tragedy. the russian foreign ministry called it a bloody terrorist attack. "i saw how the terrorists came in and started shooting "everyone," he says. "we were led to an exit but it was locked. "we ran around, looking for a way out. "in the end, we went into the basement and waited "for the emergency services." police and russian special forces rushed to the scene. some of the attackers are reported to have escaped. the search is on to find them. two weeks ago, the us embassy here issued a warning that extremists planned to target large gatherings in moscow, including concerts, within 48 hours. it's not clear whether there's any connection between that alert and this attack. the images are just horrible and just hard to watch and our thoughts, obviously, are going to be with the victims of this terrible, terrible shooting attack. who were the attackers? there's been no confirmation on their identities from the russian authorities but late tonight, islamic state claimed responsibility for the attack. the scale of destruction and loss of life is becoming clear after an assault on civilians that has shocked russia. the united states embassy in moscow said it was "shocked" by the attack. earlier we spoke to our north america editor in washington, sarah smith. she gave this analysis on the us�* reaction we are hearing that us officials have confirmed that they have intelligence which they have intelligence which they think backs up the claim of responsibility from islamic state. they think it was that group which carried out this attack. the bbc�*s news pardon here in america cbs has spoken to an intelligent source who told them there has been a steady treat stream of intelligence dating back as far as november, saying islamic state want to strike in moscow. also that information was passed on to the russian authorities under what is known as the duty to warn, that some of it was highly specific and they did to the russian government about that so we are not for sure but we assume that morning put out by the state departmentjust morning put out by the state department just over two weeks ago telling americans to stay away from large gatherings including concerts, that warning which spoke about the fact that the us was monitoring reports that extremists were preparing an imminent attack. we assume that was referring to the intelligence islamic state was wanting to strike in moscow. in the intelligence which as i say we're being told was actually being passed on to moscow. let's speak now to matthew sussex, he's an expert of russian politics and associate professor at the australian national university's strategic and defence studies centre. the us says it had warned russia of a potential attack — how does the kremlin typically approach intelligence like this from the us? it is interesting because this came out on march seven which was quite a while ago and there were alleged attempts to disrupt russian elections in the russian government came out and said this was an attempt to intimidate russians and metal intimidate russians and metal in its internal affairs so the response of the kremlin was really quite dismissive just kind of concerning, claiming responsibility. there has been plenty of chatter that islamic state has been wanting to carry out attacks beyond its normal area of operations, particularly in russia as well. could you also layout when it comes to iis why isis in particular would attack and why now? {iii particular would attack and why now? . ., , , , ., particular would attack and why now? , now? of course, russia has a lona now? of course, russia has a long history _ now? of course, russia has a long history of _ now? of course, russia has a long history of treating - long history of treating muslims and other minorities not particularly well. we have had poor treatment of people in chechnya, ingushetia and dagestan and the second chechen war around 1996 was something of a radicalised wall when you had people who went on to fight with islamic state, struggling against the russian government and since then of course russia's activities in syria and even in places like uzbekistan have made islamic state see the russian government as a primary threat. professor sussex, when it comes to the kremlin, how they likely to the kremlin, how they likely to respond to this? how they reacted to terror attacks in the past?— reacted to terror attacks in the ast? ., , ., the past? the two events that s-urin to the past? the two events that spring to mind _ the past? the two events that spring to mind most _ the past? the two events that spring to mind most readily i the past? the two events that. spring to mind most readily are the 2002 theatre seasian and the 2002 theatre seasian and the 2004 siege of the beslan school. in the case of the theatre seasian, russian officials were fairly slow to investigate and fairly slow to release any kind ofjudgement on what has happened and beslan of course there was enormous loss of life. in both cases vladimir putin, who is still the russian president, responded with extreme violence. i think perhaps in this case is perhaps not so much important as who carried out the attacks is who the russian government decides is to blame and decides who they are going to respond against. matthew sussex, thank you so much, we do appreciated. there is much more and further updates on the bbc news website and but if you would like to see how the story develops. the princess of wales has received messages of support after releasing a video, announcing that she's being treated for cancer. there'd been speculation about her health since kensington palace announced in january that she'd be recuperating from abdominal surgery until easter — she's now expected to be taking more time away from work to recover. the king is also being treated for cancer. our royal correspondent daniella relph reports. this was the last official footage of the princess of wales alongside the royal family, on christmas day at sandringham with her three children, who she is now so keen to protect after going public with news of her diagnosis. back in december, all had seemed well as she spoke to the crowd. thank you so much. that's very sweet of you to come and say hello to us. yeah, well, very happy christmas. but three weeks later, she was admitted to hospital for major abdominal surgery. it was in her post—operative tests that signs of cancer were found. tonight, buckingham palace issued a statement on behalf of the king. he said: he also said that he and the queen: a message, too, from california. the relationship is still strained but the duke and duchess of sussex issued their own statement. harry and meghan said: but perhaps the most personal message of all came from the princess's brother on instagram. james middleton posted a childhood photo with his sister and said: the clamour for information about the princess's condition has been intense. this footage, published earlier this week, filmed by a member of the public, showed her shopping in windsor with her husband last weekend. the clamour for information about the princess's condition has been intense. this footage, published earlier this week, filmed by a member of the public, showed her shopping in windsor with her husband last weekend. and this photo, released on mother's day, to ease some of the public speculation did the opposite, with the princess issuing a statement to say she'd made some edits to the image. a turning point appears to have been this thanksgiving service in windsor for king constantine of greece at the end of february. the rest of the royal family were there but the prince of wales pulled out that morning very suddenly, due to a personal matter. we now know this was around the time the princess was diagnosed and began her treatment. it's been an incredibly turbulent few weeks for the family. the couple's priority has been to protect their children and ensure they have time to explain what's wrong to prince george, princess charlotte and prince louis. they now hope the speculation will stop as they spend time privately for the easter break. in windsor, whether family lives, there was sympathy and support for the princess. i think she very brave to set the record straight and i hope she will now get privacy for her and herfamily. it is sad. you don't wish that on anybody, whoever they are. ready? the princess won't be back to a full programme of public duty for some time. we may see her occasionally, but only when her medical team have approved. for now, the princess of wales wants time, space and privacy to deal with her diagnosis and recovery. the news about the princess of wales cancer treatment has dominated news bulletins on tv and radio stations around the world. our west coast correspondent emma vardy reports from los angeles. this is an abc news special report. this is an abc news special re ort. . , , this is an abc news special re ort, . , , ., this is an abc news special reort. . ,, . report. princess catherine has now revealed _ report. princess catherine has now revealed her _ report. princess catherine has now revealed her personal- now revealed her personal health _ now revealed her personal health battle and why she kept it secret — health battle and why she kept it secret. �* , ., ., it secret. after days of global speculation. _ it secret. after days of global speculation, kate's _ it secret. after days of global speculation, kate's diagnosis j speculation, kate's diagnosis became breaking news around the world. ~ ., became breaking news around the world. ~ . , . became breaking news around the world. ~ .
