Security Beefed Up For Olympics

Russia has begun implementing stringent security measures in Sochi, one month before the start of the 2014 Winter Olympics.

Among the measures being implemented is a ban on all vehicles from the area except for those registered in Sochi or with special Olympics passes.

Two suicide bombings last week killed 34 people and injured scores of others in the city of Volgograd, which is about 400 miles away from Sochi.
