The State Department has issued an updated travel alert for Americans heading to the Olympic Games in Sochi, Russia next month, citing rising threats of violence and terror attacks.

The agency said the U.S. continues to monitor potential terrorist threats in Sochi, noting a series of recent bombings including three recent suicide bombing. It urged Americans traveling to the Olympics to register in advance and to remain vigilant while in the country.

“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 travel warning said.
