NASHVILLE, Tenn. (AP) — The Federal Aviation Administration has temporarily halted flights out of Nashville International Airport because of telecommunications issues associated with the explosion downtown.

Service was expected to resume by 3 p.m. local time. Authorities say that an explosion inside a recreational vehicle parked in downtown Nashville early Christmas morning was deliberate.

Three people were hurt in the explosion, which shattered windows and damaged buildings.

Metro Nashville Police Chief John Drake said police were responding to a report of shots fired when they encountered a recreational vehicle blaring a recording that said a potential bomb was to detonate in 15 minutes. Police evacuated nearby buildings and called in the bomb squad. Then the RV exploded.

The FBI is taking the lead in the investigation.
