Gunshots rang out as a crowd gathered Friday night to watch Soviet-era rock group Picnic perform at Crocus City Hall, Reuters reported. About 6,000 people were estimated to be at the venue when the shooting began, according to BBC News. The attackers set fires, which grew strong enough to cause the roof to collapse, the news network reported.
A senior Russian official told CNN on Monday that the death toll from Friday’s attack rose from 137 to 139 after two people died in hospitals. At least three children were among those killed, the news network reported.
Rescuers continued to search through the rubble for victims on Monday, according to BBC News.
The Islamic State group claimed responsibility for the attack, which claimed dozens of lives and left more than 180 people injured, according to Reuters.
U.S. officials said a branch of the group called Islamic State Khorasan, or ISIS-K, carried out the attack, The New York Times reported. President Vladimir Putin has suggested that Ukraine might be connected to the attack, though intelligence officials and Ukrainian President Volodymyr Zelenskyy have denied the allegation.
