Fox News is reporting U.S. counterterrorism operatives are searching for Ruzanna Ibragimova, a "white widow," - the wife of a dead terrorist - who is believed to have traveled from Dagestan to Sochi and may have breached the 1,500-mile security area. Ibragimova's husband was killed during a previous terrorist attack on a Moscow theater.
 
Her photo was distributed to Russian and U.S. security officials last week. An accompanying memo said Ibragimova is believed to be associated with "illegal armed groups for the organization of terrorist acts in the zone of the 2014 Olympics."
 
A U.S. security forces memo said the notice "is the first sign that terrorists may have managed to penetrate the security cordon."
 
Russia has about 40,000 security and police personnel in the area to deter attacks.
 
The news of the possible terrorist breach is just the latest security threat to the Olympics which are set to begin next month. Terrorist groups have already made videotaped threats to disrupt the proceedings, prompting U.S. Secretary of Defense Chuck Hagel to offer security assistance to the Russians.
 
This week, Sen. Angus King of Maine joined a list of lawmakers questioning the security of the games.
 
"I would not go, and I don't think I would send my family," he said. ""It's just such a rich target."
 
Also, CNN is reporting the U.S. is putting its warships on standby to evacuate Americans in the event of a terror attack.
