The group Picnic was going to play that day at the Crocus room, on the outskirts of Moscow, when a terrorist commando burst into the place. At least 137 people lost their lives.

The band's leader, Edmund Schkliarski, addressed the families of the victims and all those who attended their concert: "I give you my condolences, but there are no words that can revive or console people" The tragedy has reached many regions of Russia. There is no protocol for declaring a day of mourning in Russia. The last time Russia was in mourning was in March 2018 when 64 people died when a shopping center in Kemerovo burned.
