U.S. Official Says 'Number of Specific Threats' at Games

WASHINGTON — A top U.S. counterterrorist official said there are "a number of specific threats" aimed at the Winter Olympics that start this week in Sochi — with the greatest danger coming from the Caucasus Emirate, which has threatened to attack the games.

Matthew Olsen, director of the National Counterterrorism Center, told Congress on Tuesday that the U.S. and Russia are tracking threats of "varying degrees" of credibility. He said potential attacks seem more likely outside the venues for the Games, and instead in the area or region around Sochi.

He described intelligence sharing with Russia as "good."

FBI Director James Comey said U.S. cooperation with the Russian Security Service has improved.

Top U.S. security officials told President Barack Obama that all appropriate steps are being taken to keep Americans safe.
