On 6 October 1981, Sadat was assassinated during the annual victory parade held in Cairo to celebrate Egypt's crossing of the Suez Canal. Islambouli emptied his assault rifle into Sadat's body while in the front of the grandstand, mortally wounding the President. In addition to Sadat, eleven others were killed, including the Cuban ambassador, an Omani general, a Coptic Orthodox bishop and Samir Helmy, the head of Egypt's Central Auditing Agency (CAA). Twenty-eight were wounded, including Vice President Hosni Mubarak, Irish Defence Minister James Tully, and four US military liaison officers.
