Police bombed MOVE headquarters in Philadelphia, killing six adults and five children, and destroying the homes of 250 city residents.

The 1985 MOVE bombing, locally known by its date, May 13, 1985, was the aerial bombing and destruction of residential homes in the Cobbs Creek neighborhood of Philadelphia, Pennsylvania, United States, by the Philadelphia Police Department during an armed standoff with MOVE, a black liberation organization. Philadelphia police were shot at as they attempted to evict MOVE members from a house. Philadelphia police aviators then dropped two explosive devices from a Pennsylvania State Police helicopter onto the roof of the occupied house. For 90 minutes, the Philadelphia Police Department allowed the resulting fire to burn out of control, destroying 61 previously evacuated neighboring homes over two city blocks and leaving 250 people homeless. Six adults and five children were killed in the attack, with one adult and one child surviving who were occupants of the home. A lawsuit in federal court found that the city used excessive force and violated constitutional protections against unreasonable search and seizure.
