As envisioned in the Oslo Accords, Israel allowed the PLO to establish interim administrative institutions in the Palestinian territories, which came in the form of the PNA. It was given civilian control in Area B and civilian and security control in Area A, and remained without involvement in Area C. In 2005, following the implementation of Israel's unilateral disengagement plan, the PNA gained full control of the Gaza Strip with the exception of its borders, airspace, and territorial waters. Following the inter-Palestinian conflict in 2006, Hamas took over control of the Gaza Strip (it already had majority in the PLC), and Fatah took control of the West Bank. From 2007, the Gaza Strip was governed by Hamas, and the West Bank by Fatah.
