Mounting tensions between Israel and its Arab neighbours culminated in six days of hostilities starting on 5 June 1967 and ending on 11 June - six days which changed the face of the Middle East conflict.
Israel seized Gaza and the Sinai from Egypt in the south and the Golan Heights from Syria in the north. It also pushed Jordanian forces out of the West Bank and East Jerusalem.
Egypt's powerful air force was put out of action on the first day of fighting when Israeli jets bombed it on the ground in a pre-emptive strike.
The territorial gains doubled the area of land controlled by Israel. The victory heralded a new age of confidence and optimism for Israel and its supporters.
The UN Security Council issued resolution 242, stressing "the inadmissibility of the acquisition of territory by war and the need to work for a just and lasting peace in which every State in the area can live in security". The resolution called for the "withdrawal of Israeli armed forces from territories occupied in the recent conflict". It also called for an end to "all claims or states of belligerency and respect for... the sovereignty... of every state in the area and their right to live in peace... free from threats or acts of force".
According to the UN, the conflict displaced another 500,000 Palestinians who fled to Egypt, Syria, Lebanon and Jordan.
