On the evening of March 22, terrorists targeted the Crocus City Hall music venue on the outskirts of Moscow, Russia, killing at least 139. The attack was the deadliest terror attack in Russia in 20 years.

A large number of Moscow citizens have since donated blood. CGTN Stringer went to a blood donation center in Moscow and saw long lines. Some people said they felt sorry for the victims' families and were donating to show support for the victims.
