Palestinian leader Mahmoud Abbas and Lebanese Prime Minister Fuad Saniora held talks at a U.N.-sponsored meeting Tuesday. The two leaders did not comment to reporters as they went into talks at a Paris hotel. But a Lebanese diplomat said they were expected to discuss possibilities for disarming Palestinian refugees in Lebanon, as well as regulating weapons within refugee camps. They also were expected to talk about the possibility of the Palestinians opening an embassy in Lebanon for the first time, and general economic and social relations, the Lebanese official was quoted as saying by The Associated Press. After the talks, Abbas was to leave for Madrid, Spain, then head to Washington. Saniora, in town for a two-day visit, was also meeting Tuesday with Prime Minister Dominique de Villepin.
