Moscow Concert Hall Attack
Gunmen who opened fire at a Moscow concert hall killed more than 60 people and wounded over 100 while sparking an inferno, authorities said, with the Islamic State group claiming responsibility.
Attackers dressed in camouflage uniforms entered the building, opened fire and threw a grenade or incendiary bomb.
Fire quickly spread through the Crocus City concert hall in Moscow's northern Krasnogorsk suburb, as smoke filled the building and screaming visitors rushed to emergency exits.
Russia's Investigative Committee said that more than 60 people had been killed, raising an earlier toll of 40, according to Russian news agencies.
Russia's Health Minister Mikhail Murashko said 115 people were hospitalized, including five children, one of whom was in grave condition. Of the 110 adult patients, 60 were in serious condition.
Authorities said a "terrorist" investigation had been started and President Vladimir Putin was receiving "constant" updates.
Russia's national guard said it was on the scene and looking for the perpetrators.
The Islamic State group said its fighters attacked "a large gathering" on Moscow's outskirts and "retreated to their bases safely".
Security services quoted by Interfax said between two and five people "wearing tactical uniforms and carrying automatic weapons" opened fire on guards at the entrance and then started shooting at the audience.
A witness said it was a few minutes before the start of the concert when automatic gunfire rang out.
About 100 people escaped through the theater basement, while others were sheltering on the roof, the emergency services ministry said.
Three helicopters were involved in efforts to put out the fire, dumping water on the giant concert venue that can hold several thousand people and has hosted top international artists.
Shortly after midnight, the emergency ministry said the fire had been contained.
