Tragedy struck Moscow just days after President Vladimir Putin's victory in the election. A group of gunmen opened fire in a large concert hall, killing at least 60 people and injuring over 100. The attackers also set the venue ablaze. Authorities are investigating the incident as a terrorist attack.
The attackers stormed Crocus City Hall, a music venue on the western outskirts of Moscow, with a capacity of 6200 people. Vladimir Putin was notified within minutes of the attack.
The Islamic State group claimed responsibility for the attack, saying its fighters attacked "a large gathering" on Moscow's outskirts and "retreated to their bases safely".
