The West Bank was annexed by Jordan in 1950, following the Arab rejection of the UN decision to create two states in Palestine. Only Britain recognized this annexation and Jordan has since ceded its claim to the territory to the PLO. The West Bank was occupied by Israel in 1967 during the Six-Day War. The population are mainly Palestinians, including refugees of the 1948 Arab-Israeli War. From their occupation in 1967 until 1993, the Palestinians living in these territories were under Israeli military administration. Since the Israel–PLO letters of recognition, most of the Palestinian population and cities have been under the internal jurisdiction of the Palestinian Authority, and only partial Israeli military control, although Israel has on several occasions redeployed its troops and reinstated full military administration during periods of unrest. In response to increasing attacks as part of the Second Intifada, the Israeli government started to construct the Israeli West Bank barrier. When completed, approximately 13% of the Barrier will be constructed on the Green Line or in Israel with 87% inside the West Bank.
