40 Dead, 145 Injured in Moscow Concert Hall Attack; Islamic State Claims Responsibility

Several assailants entered a large concert hall in Moscow on Friday, opening fire on the crowd and killing at least 40 people. Over 100 individuals were injured, and the venue was set ablaze in the attack, which occurred just days after President Vladimir Putin's electoral victory. The Islamic State group claimed responsibility for the incident via social media channels, though this could not be independently verified. Moscow Mayor Sergei Sobyanin described the event as a "huge tragedy," and state authorities are investigating it as terrorism.The assault took place at Crocus City Hall, a music venue on Moscow's western edge, during a performance by Russian rock band Picnic. The Federal Security Service reported 40 dead and over 100 injured, with some Russian news reports suggesting that more people could have been trapped by the fire that broke out after the assailants threw explosives. Health authorities released a list of 145 injured individuals, including 115 who were hospitalized and five children.Videos from outside the venue showed the building on fire, with a large cloud of smoke rising into the night sky. The street was illuminated by the flashing blue lights of numerous emergency vehicles, while fire helicopters circled overhead to dump water on the blaze, which took hours to contain.The prosecutor's office stated that several men in combat fatigues entered the concert hall and fired on concertgoers. Repeated volleys of gunfire could be heard in videos posted by Russian media and on Telegram channels. Some Russian news outlets suggested that the assailants fled before special forces and riot police arrived.In a statement posted by its Aamaq news agency, the Islamic State group claimed responsibility for attacking a large gathering in Krasnogorsk on Moscow's outskirts, killing and wounding hundreds. The authenticity of this claim could not be immediately verified.As the fire continued to burn, statements of outrage, shock, and support for those affected poured in from around the world. Some commentators on Russian social media questioned how authorities who relentlessly surveil and pressure Kremlin critics failed to identify the threat and prevent the attack.Russian officials said security has been tightened at Moscow's airports, railway stations, and subway system. Moscow's mayor cancelled all mass gatherings, and theatres and museums shut for the weekend. Other Russian regions also tightened security measures.The Kremlin did not immediately blame anyone for the attack, but some Russian lawmakers accused Ukraine of being behind it and called for increased strikes. Hours before the attack, the Russian military launched a sweeping barrage on Ukraine's power system, crippling its largest hydroelectric plant and other energy facilities and leaving more than a million people without electricity.Dmitry Medvedev, deputy head of Russia's Security Council, said that if Kyiv's involvement in the attack is proven, all those involved "must be tracked down and killed without mercy." Mykhailo Podolyak, an adviser to Ukrainian President Volodymyr Zelenskyy, denied Ukraine's involvement in the concert hall attack. "Ukraine has never resorted to terrorist methods," he posted on X. "Everything in this war will be decided only on the battlefield."John Kirby, spokesman for the White House National Security Council, said Friday that he couldn't yet speak about all the details but that "the images are just horrible." "Our thoughts are going to be with the victims of this terrible shooting attack," Kirby said.
