The State Department Friday alerted U.S. citizens planning to attend the 2014 Olympic Games in Russia that they should remain attentive at all times.
"Large-scale public events such as the Olympics present an attractive target for terrorists, and the U.S. government continues to monitor reported threats of potential terrorist attacks in Sochi or in Russia in general," the statement read.
The State Department warned about potential bombings, hostage takings and so-called "black widow" suicide bombers in Sochi.
"There is no indication of a specific threat to U.S. institutions or citizens, but U.S. citizens should be aware of their personal surroundings and follow good security practices," the statement added.
The State Department also warned citizens to avoid large gatherings or demonstrations, which "can develop quickly and unpredictably, sometimes turning violent."
