On 5 June 1967 the Six-Day War began after an Israeli strike wiped out Egypt's Air Force. The Egyptian army commander in Cairo transmitted to General Riad that the Israeli strike had failed, and that Israel's Air Force was almost wiped out. Based on the misleading information from Cairo, Riad ordered the Jordanian army to take offensive positions and attack Israeli targets around Jerusalem. Jordanian Hawker Hunters made sorties but were destroyed by Israel when they went to refuel; Syria's and Iraq's air forces followed. Israel's air superiority on the first day of war proved decisive. Two Israeli jets attempted to assassinate Hussein; one was shot down by anti-aircraft artillery, and the other shot directly at Hussein's office in the royal palace. Hussein was not there, the CIA director in Amman Jack O'Connell relayed a message threatening the Israelis, and the attempts stopped. The Jordanians had prepared a war strategy, but the Egyptian commander insisted to build his strategy based on the misleading information from Egypt.
