Sochi, Russia -

Russian security officials are hunting down three female potential 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 on Tuesday contain warnings about three potential suicide bombers.

Police said that one of them, Ruzanna Ibragimova, a 22-year-old widow of a slain Islamic militant, was at large in Sochi.

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

Security officials in Sochi were not available for comment on Tuesday morning.

The Black Sea resort town will host the games in February amid concerns about security and potential terrorist attacks. - Sapa-AP
