At least 60 people were killed and 115 others injured during an attack in a concert hall on Friday. Three men armed with Kalashnikov-type assault rifles were filmed shooting at point-blank range at civilians trying to escape.

They throw at least one incendiary bomb into the building, causing a gigantic fire. Hundreds of people managed to evacuate from the basements. But the flames rose to the roof, where many civilians took refuge. Chilling videos are broadcast on social networks. The attackers are still being sought.
