Saudi Arabia's King Abdullah held an unannounced meeting Sunday with Palestinian Authority Mahmoud Abbas to discuss the recent escalation in Israeli-Palestinian tensions, a Palestinian official said. The meeting in the Saudi capital, Riyadh, came a day after the Palestinian leader from the Fatah movement met with Khaled Mashaal, the exiled political leader of Hamas, in Cairo. Their talks were the first since their blocs formed a coalition government in March under Saudi Arabian mediation. During Sunday's meeting, Abbas updated the Saudi king on the deteriorating security situation in the Gaza Strip, a Palestinian official in Riyadh said on condition of anonymity because he was not authorized to speak to the media. The Palestinian official said the two Arab leaders discussed "how to re-establish security (in Gaza) and reactivate the cease-fire."
