The opening as it read in 2005
USS Liberty incident was an attack on a US Navy intelligence ship in international waters near the Sinai Peninsula , north of El Arish , by Israeli fighter planes and torpedo boats on June 8 , 1967 , during the Six-Day War between Israel and the Arab States. In all, 34 American servicemen were killed and 173 wounded in the attack. Vessel details can be found in the USS Liberty (AGTR-5) article. Israel maintains that the incident was entirely due to error, a finding supported by a number of United States government reports and officially accepted by the United States. Israel contends it was assured by the United States that no US ships were in the area, and that its air and naval forces wrongly identified the Liberty at various stages as a Russian intelligence ship providing information to the Arabs or as the Egyptian vessel "El Quseir," which is a horse carrier one-fourth the size of the Liberty . The United States and Israel exchanged diplomatic notes after several inquiries, and the U.S. accepted an indemnity of $13 million. Surviving crew members, as well as a number of Western observers and former US government officials (including then CIA director Richard Helms ), and then- Secretary of State Dean Rusk assert that the attack was premeditated and deliberate and that Israel knew the ship was American. Help arrives after the Israeli attack on USS Liberty .1
