WASHINGTON (WJZ) — A portion of a park in northeast Washington, D.C., is closed after an unexploded World War I-era ordnance was found during construction work, the National Park Service said.

The discovery happened Wednesday at Fort Totten Park after heavy rains revealed the ordnance, officials said. Construction on a nearby trail has been suspended.

The park service said the area is roped off with caution tape, with signs and a fence set to go up. People are being asked to avoid the area.

The Army will analyze the ordnance and likely destroy it at Marine Corps Base Quantico, officials said.
