SOCHI, Russia (AP) — 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 by an Associated Press reporter at a central Sochi hotel today contain warnings about three potential suicide bombers. Police say that one of them (Ruzanna Ibragimova), a 22-year-old widow of a slain Islamic militant, is at large in Sochi.

Russian authorities have blamed the so-called "black widows" of slain insurgents for previous suicide attacks in the country.
