The combined air and sea attack lasted 23 minutes and was carried out by air strafing and napalm bombing by four Mirage III and Super Mystères fighters, and gunfire and torpedo launches from the motor boats, one of which impacted the ship. Israeli forces terminated their attack after the torpedo impact, believing the ship to be sinking.[5] At the time, the ship was in international waters north of the Sinai Peninsula, about 25.5 nautical miles (47.2 km; 29.3 mi) northwest from the Egyptian city of Arish.[1][6]
