The USS Liberty incident was an attack on a United States Navy technical research ship, USS Liberty, by Israeli Air Force jet fighter aircraft and Israeli Navy motor torpedo boats, on 8 June 1967, during the Six-Day War.[2] The combined air and sea attack killed 34 crew members (naval officers, seamen, two marines, and one civilian), wounded 171 crew members, and severely damaged the ship.[3] At the time, the ship was in international waters north of the Sinai Peninsula, about 25.5 nmi (29.3 mi; 47.2 km) northwest from the Egyptian city of Arish.[1][4]

Israel apologized for the attack, saying that the USS Liberty had been attacked in error after being mistaken for an Egyptian ship.[5] Both the Israeli and U.S. governments conducted inquiries and issued reports that concluded the attack was a mistake due to Israeli confusion about the ship's identity.[6] Others, including survivors of the attack, have rejected these conclusions and maintain that the attack was deliberate.[7]
