Authorities in West Virginia say a pipe bomb exploded outside of a bar, killing a man. No other injuries were reported.

Cabell County Sheriff Tom McComas said the man who was killed apparently brought the bomb to the area outside the bar Friday morning. It detonated around 2:30 a.m.

He says 20 to 30 residents were evacuated from the area while investigators searched for more bombs. West Virginia State Police said the agency's bomb technicians defused two other bombs that were found.

McComas says the investigation is ongoing. Few other details were released.

A phone message left by The Associated Press at the Cabell County Sheriff's Office was not immediately returned.
