The national anti-terrorism committee claimed the bombers were members of a militant group in the violence-hit region Dagestan and revealed they had also arrested two other accomplices linked to the attack.

Security has heavily increased in Russia ahead of the Sochi Winter Olympics which start next week after fears were raised that militants could target the games.
