U.S. Park Police evacuated several homes, as well as the Egyptian consulate residence located near Rock Creek Park after the discovery of an explosive in the park; the bomb squad has issued an "all clear" for the site.

An FBI (web) spokeswoman says the live, unexploded grenade was found across the street from an office of the Egyptian Embassy. She says there is no known terrorist connection.

The embassy office was evacuated while military bomb experts worked on safely removing the grenade.

At 7:55 a.m., park police were notified of a suspicious device in the playing field north of Morrow Drive.

U.S. Park Police spokesman Sgt. Robert Lachance spoke with ABC 7/NewsChannel 8 reporter Jennifer Donelan on the most recent developments.

U.S. Park Police spokesman Sgt. Robert Lachance says a National Park Service maintenance worker found the explosive. He says authorities determined it's a real grenade.

A perimeter was established, and a D.C. metro police bomb squad has declared the scene cleared.

The grenade was found near a trash can in a plastic bag marked "inert."

Officials have confirmed that the grenade had no powder in it; police favored a cautious approach, and have now verified that the grenade was not live.
