Palestinian-on-Palestinian violence

Fighting among rival Palestinian and Arab movements has played a crucial role in shaping Israel's security policy towards Palestinian militants, as well as in the Palestinian leadership's own policies. As early as the 1930s revolts in Palestine, Arab forces fought each other while also skirmishing with Zionist and British forces, and internal conflicts continue to the present day.

In the First Intifada, more than a thousand Palestinians were killed in a campaign initiated by the Palestine Liberation Organization to crack down on suspected Israeli security service informers and collaborators. The Palestinian Authority was strongly criticized for its treatment of alleged collaborators, rights groups complaining that those labeled collaborators were denied fair trials. According to a report released by the Palestinian Human Rights Monitoring Group, less than 45 percent of those killed were actually guilty of informing for Israel.
