Six-Day War
In May 1967, Egyptian President Gamal Abdel Nasser was informed by the Soviet Union that Israel was moving its troops on its border with Syria. Because of that false information, Nasser decided to expel the UN troops from the Sinai Peninsula and to move his army close to the Egyptian border with Israel. In the last days of May, other Arab countries such as Jordan and Iraq gathered troops and prepared for battle. The main event that led to the beginning of the war was the closing of the Tiran Straits on 23 May 1967, when Egypt blocked Israel's only access to the Red Sea.
