On 15 November 1988 in Algiers, Yasser Arafat, Chairman of the PLO, proclaimed the establishment of the State of Palestine. A year after the signing of the Oslo Accords in 1993, the Palestinian National Authority was formed to govern (in varying degrees) areas A and B in the West Bank, comprising 165 "islands", and the Gaza Strip. After Hamas became the PNA parliament's leading party in the most recent elections (2006), a conflict broke out between it and the Fatah party, leading to Gaza being taken over by Hamas in 2007 (two years after the Israeli disengagement).
