The USS Liberty incident was an attack on a U.S. Navy intelligence ship, USS Liberty, in international waters about 12.5 nautical miles (23 km) from the coast of the Sinai Peninsula, north of El Arish, by Israeli fighter planes and torpedo boats on June 8, 1967.
It occurred during the Six-Day War, a conflict between Israel and the Arab states of Egypt, Jordan and Syria. The Israeli attack killed 34 U.S. servicemen and wounded at least 173. The attack was the second deadliest against a U.S. Naval vessel since the end of World War II, surpassed only by the Iraqi Exocet missile attack on the USS Stark on May 17, 1987, and marked the single greatest loss of life by the U.S. Intelligence Community.
