Palestinian Authority chief Mahmud Abbas has held talks with the revolutionary council of his Fatah faction, days before the Palestinian leader meets Israeli prime minister. Abbas on Saturday conducted talks with more than 100 members of his Fatah party, and a top aide said the aim of the summit on Tuesday was to declare a mutual ceasefire between Palestinians and Israelis. "The revolutionary council of Fatah is holding an important meeting in the presence of Abu Mazin (Abbas) to discuss the summit, political and security questions and the results of contacts with Israel," said Palestinian Authority spokesman Nabil Abu Rudaina. "We intend to work so that a mutual ceasefire can be declared between the Palestinians and Israelis at the Sharm al-Shaikh summit," he said. "We are also demanding the liberation of 8000 Palestinian prisoners held by Israel and hope to be able to sort out the differences in this respect in 48 hours," he added.
