Footage of gunmen reinforces terror group’s claim to have masterminded worst terror attack on Russia in two decades
The videos, which were published by IS’s news agency Amaq, showed the gunmen filming themselves as they hunted concertgoers through the lobby of the Crocus City Hall and fired at them from pointblank range, killing scores of people. At one point, one of the gunmen tells another to “kill them and have no mercy”.
