Men in camouflage broke into a Moscow concert hall and opened fire, shooting an unknown number of people, Russia’s prosecutor general said.
The terror group ISIS has claimed responsibility but did not provide proof of the claim, which was made on ISIS-affiliated news agency Amaq on Telegram.
Russia's Investigative Committee said that more than 60 people are dead after the attack at Crocus City Hall. Officials have said more than 100 others were injured.
A fire also started inside Crocus City Hall, a large concert venue northwest of central Moscow. Firefighters have evacuated about 100 people from the basement of the building and efforts are underway to rescue people from the roof, Russian emergency officials said.
Russia officials said they were investigating the attack as a terrorist act.
A popular rock band was scheduled to play what appeared to be a sold-out show at the venue, which has a maximum capacity of more than 9,000 people.
