This is a fake. In fact, these militants were killed during a shootout in Ingushetia back in early March.

A list of five men allegedly wanted for the attack on Crocus is circulating around the web (in particular, photos are given by all sorts of anonymous tg-channels).

According to the FSB and the Investigative Committee of the Russian Federation, the security forces were confronted by a group organized by Amirkhan Gurazhev, who was wanted for terrorist crimes. Five alleged accomplices were killed along with him.
