Horrifying video posted online appears to show the moment gunmen burst into a big concert hall on the edge of Moscow on Friday and sprayed visitors with automatic gunfire.
At least 15 concertgoers have been killed so far and the building is now on fire.
The attack comes days after President Vladimir Putin cemented his grip on the country in a highly orchestrated electoral landslide.
There were no immediate claims of responsibility for the raid, the worst terror attack in Russia in two decades that came as the fighting in Ukraine dragged into a third year.
Moscow Mayor Sergei Sobyanin described the attack as a “huge tragedy.”
