Gunmen have attacked a concert hall on the fringes of Moscow, killing at least 60 people and wounding 100 more, Russian security services say. At least four attackers clad in camouflage gear took part in the attack, in the north-west suburb of Krasnogorsk, BBC-verified video shows. Crocus City Hall was about to host a rock concert when the gunmen burst into the foyer and then the theatre itself. Much of the building was engulfed by fire and part of the roof collapsed.
Children are said to be among the casualties and the Russian foreign ministry has condemned a "terrorist attack".
According to an unverified statement online, militant group Islamic State said it was behind the attack.
US officials told CBS, the BBC's partner service in the US, that it had obtained intelligence that showed IS had wanted to attack Russia. The White House said it had warned Russia earlier this month of plans for a potential attack in Moscow targeting "large gatherings".
Russia's National Guard said it had special units working at the scene to hunt down the attackers. Top Russian officials also headed to Krasnogorsk
