This Tuesday, Jan. 21, 2014 photo shows a police leaflet showing Ruzanna Ibragimova and contains warnings about three potential suicide bombers including Ibragimova, at a hotel in Sochi. While most suicide bombers are men, Islamic militant groups have occasionally deployed women to carry out such attacks. Long before the rise of Islamic radicalism, women suicide bombers were used by leftist and separatist groups in the Arab and beyond. (AP Photo/Nataliya Vasilyeva)
