Police hunting for three potential female suicide bombers in Sochi, including the wife of Islamic militant who was seen on a downtown street

Russian security officials are hunting down three potential female suicide bombers, one of whom is believed to be in Sochi, where the Winter Olympics will begin next month.
Police leaflets seen at a central Sochi hotel yesterday contain warnings about the women.
One of them, Ruzanna Ibragimova, a 22-year-old widow of an Islamic militant, is said to be at large in Sochi.
Police material distributed to the hotel staff also included pictures of two other women in veils: Zaira Aliyeva, 26, and Dzhannet Tsakhayeva, 34. It said they had been trained "to perpetrate acts of terrorism".
