The State Department issued a travel warning Friday to Americans planning to attend the Sochi winter Olympic games in Russia next month.
The warning comes after two suicide bombings occurred in December in the city of Volgograd, 400 miles from Sochi. More than 30 people were killed.
Americans who plan to attend the winter Olympics “should remain attentive regarding their personal security at all times,” the department said in the alert. They should also expect an increased police presence.
