In January 1997, Israel and the Palestinian Liberation Organization (PLO) signed the Protocol Concerning the Redeployment in Hebron. In the agreement, Israel handed over control of 80 per cent of Hebron city (18 km² known as H1) to the Palestinian Authority, while keeping full control over the remaining 20 per cent (known as H2). H2 includes four Israeli settlement compounds, home to a few hundred Israeli settlers and a population of over 40,000 Palestinians.
