The Palestinians demanded complete sovereignty over East Jerusalem and its holy sites, in particular, the Al-Aqsa Mosque and the Dome of the Rock, which are located on the Temple Mount (Haram al-Sharif), a site holy in both Islam and Judaism, and the dismantling of all Israeli neighborhoods built over the Green Line. The Palestinian position, according to Mahmoud Abbas, at that time Arafat's chief negotiator, was that: All of East Jerusalem should be returned to Palestinian sovereignty. The Jewish Quarter and Western Wall should be placed under Israeli authority, not Israeli sovereignty. An open city and cooperation on municipal services.
