VIRGINIA BEACH, Va. (AP) — The U.S. Navy says "a significant" amount of jet fuel has leaked at an air station in Virginia Beach.

Navy spokesman Jim Moir said in a press release Thursday that the fuel leaked from a tank at Naval Air Station Oceana. Some of the liquid spilled into a ditch right outside the base, closing a road.

Moir said the spill was discovered and contained about 6:30 a.m. He said it should be cleaned up within 48 hours. The cause of the spill remains under investigation.

Base operations have not been affected. No injuries have been reported.
