Saudi Arabia has offered proposals to back Egyptian-led Palestinian reconciliation efforts crucial to forming a lasting cease-fire between Hamas and Israel, a senior Palestinian official said on Tuesday. The Palestinian representative to Egypt, Nabil Amr, said that he was not authorized to disclose the details about the proposals, but that Arab ministers meeting Tuesday in the United Arab Emirates would include them in their discussions. Egypt is leading these efforts between rival Palestinian factions - Hamas and Fatah. These efforts are key to the cease-fire and the revival of peace talks with Israel. Saudi Arabia held a breakthrough Palestinian reconciliation meeting in 2007. It produced a unity government, which later collapsed after bloody infighting.
