At least 133 people were killed in the attack on Crocus City Hall near Moscow. The attack is the worst in Russia in many years.
There have been a number of deadly explosions and bombings in the country in recent decades. Putin is using the attacks to launch a bloody campaign in the Caucasus and to consolidate his rule. The Russian capital was particularly affected at the beginning of the millennium by a series of attacks on apartment buildings and the subway. In the spring of 2017 it will hit the St. Petersburg subway.
