The U.S. Embassy in Mexico City is prohibiting U.S. government employees from to the resort town Playa del Carmen.
The U.S. Consular Agency in Playa del Carmen in the state Quintana Roo will be closed “until further notice,” the embassy said.
The embassy said it had “received information about a security threat” on Wednesday. It did not specify what that threat is.
The alert, issued Wednesday night, says U.S. government employees have to cease traveling to the town “immediately” and “until further notice.”
USA Today says that "The move comes after the Feb. 21 explosion on the ferry that links Playa del Carmen with the town of Cozumel. The incident injured 25 people, including two Americans."
