The governorates in the West Bank are grouped into three areas per the Oslo II Accord. Area A forms 18% of the West Bank by area, and is administered by the Palestinian government. Area B forms 22% of the West Bank, and is under Palestinian civil control, and joint Israeli-Palestinian security control. Area C, except East Jerusalem, forms 60% of the West Bank, and is administered by the Israeli Civil Administration, except that the Palestinian government provides the education and medical services to the 150,000 Palestinians in the area. More than 99% of Area C is off limits to Palestinians. There are about 330,000 Israelis living in settlements in Area C, in the Judea and Samaria Area. Although Area C is under martial law, Israelis living there are judged in Israeli civil courts.
