Russian police and security agents have circulated photos of a female terrorist in Sochi, the host city of next month's Winter Olympics. The would-be bomber, identified as Ruzana Ibragimova, 22, was last seen on Sovetskaya Street in downtown Sochi, a source close to law enforcement agencies said. A local police chief said Ibragimova also had a nickname, Salima. A group calling itself the “Ansar al-Sunna” has claimed responsibility for the twin terror attacks on 29 and 30 December in the city of Volgograd which killed 34 people and wounded more than 70.
