A maintenance worker found a grenade across from the Egyptian Embassy in Washington, D.C., Wednesday, but the FBI was quick to say terrorism isn't suspected.

The jarring discovery of the weapon — which wasn't live, FBI spokeswoman Debbie Weierman told FOXNews.com — brought the military and police bomb squads to the scene and prompted several homes in the area to be evacuated.

The grenade hadn't exploded when it was found Wednesday morning in a ball field across from the embassy, near 16th Street and Rock Creek State Park, according to the FBI.

"We were at the scene and it was determined that it was not a live grenade," Weierman told FOXNews.com, correcting earlier reports.

There was no known terrorism link, she said, and the case is now being handled solely by U.S. Park Police.

The embassy office was evacuated while military bomb experts removed the explosive.

A National Park Service maintenance worker found the explosive about 8 a.m. Wednesday, said U.S. Park Police spokesman Sgt. Robert Lachance.

He said authorities determined it's a real grenade. A D.C. police bomb squad also was working to remove it.

Police temporarily closed 16th Street, a busy commuter route, before clearing the scene.

Some homes along Kennedy Place were evacuated as a precaution.
