Islam Khalilov, 15, worked as a cloakroom attendant at Moscow's Crocus City Hall. He was present at the time of the assault and helped evacuate around a hundred people.
In a video circulating on social media, he can be seen running down corridors, shouting at a line of people following him. Grand Mufti Ravil Gaynutdin, representative of Muslims in Russia, also declared to the Russian media Ria Novosti that he would offer the teenager a medal for his merits.
