There are two factions in the organization: Fatah and Hamas. From 1993 to 1998, the PLO made agreements with Israel that created the Palestinian National Authority (PNA). The PNA is in charge of governing Gaza and the West Bank. The leader of the PLO at the time was Yasser Arafat. He signed a series of peace treaties called the Oslo Accords with Yitzhak Rabin who was the Prime Minister of Israel at the time. Many politicians in the PLO and Israel did not agree with the Accords. Far right Israeli Yigal Amir who disagreed very much with the agreements killed Israeli prime minister Rabin.
