(CNN) - News that a terrorist could be inside Sochi, the host city of the 2014 Winter Olympics, has fueled debate over security at the upcoming Games.
Police in Sochi handed out fliers at area hotels warning workers to be on the lookout for Ruzanna "Salima" Ibragimova, described as the widow of a member of a militant group from the Caucasus region. Some describe her as a "black widow" - a notorious type of terrorist that's emerged in Russia's clashes with Chechen separatists.
"It has implications. Can we in this day and age carry out a world event and do it securely?" said Rep. William Keating, member of the House Homeland Security committee, who is currently in Sochi.
Russia said Tuesday it killed seven terrorists in Dagestan, including rebel group leader Makhmud Aliev and another "black widow" Zaira Alieva.
"Those insurgents are still threats, and still exist," said Keating.
