For background on this ongoing story, please read our report from yesterday (Tuesday, 1/21):
New details fueled debate Monday over security at the upcoming Winter Olympic Games in Sochi: Wanted posters of a terrorism suspect on the loose, warships at the ready and a video threat from beyond the grave.
Russian President Vladimir Putin stressed that his country has stepped up security and is prepared to handle any threats.
But some U.S. lawmakers - and at least one Olympic athlete - have said they're worried about the situation.
Hotels warned about terror suspect
Police in Sochi have handed out fliers at area hotels warning of a woman they believe could be a terrorist and who may currently be in the city.
One flier, obtained by CNN, asks 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.
The woman, according to the flier, may be involved in organizing "a terrorist act within the 2014 Olympic region."
