UNITED NATIONS - UN Secretary-General Ban Ki-moon said on Wednesday that the Arab League chief told him he intends to revive an Arab League monitoring mission in Syria, which has collapsed amid continuing violence there.Nabil Elaraby asked for UN help with the project during a telephone conversation on Tuesday, Ban told reporters after briefing the UN Security Council on a visit he just paid to the Middle East.Elaraby further proposed a joint UN-Arab League observer mission, including a joint special envoy, for Syria, where a harsh crackdown on an 11-month-old uprising has left thousands dead, according to UN figures. Ban said the United Nations was ready to help, but indicated no decision had been taken.Elaraby "informed me that he intends to send the Arab League observer mission back to Syria and asked for UN help," the UN chief said.The mission first went to Syria in December, reaching a strength of 165 members, but the Arab League suspended it on January 28 because of worsening violence, although it did not wind it up altogether. Six Gulf Arab states, Jordan and Morocco have pulled out their teams, but other members are still in Syria.Elaraby told Reuters in an interview in Cairo on Monday that a new mission could be sent but under different terms and with more members."If we are going to send another mission, and we are contemplating that, it has to be stronger in numbers and in equipment. The mandate has to be different," he said, adding it would need international not just Arab backing this time.Arab foreign ministers have been planning to meet on Sunday to discuss the fate of the monitoring mission. It was not immediately clear whether the plan to revive the mission would go ahead anyway.despite a recent Hamas-Fatah reconciliation agreement. "I believe that Palestinian reconciliation and negotiations with Israel need not be mutually exclusive," he said. Ban also urged the two sides to submit concrete proposals on security and territory. "Goodwill gestures and positive facts on the ground will go a long way toward setting the stage for progress in the negotiations."In response to a question about the timing of negotiations, Ban said "while the situation may look fragile and volatile in the region, this is the right moment to enter into negotiations to promote peace and stability in the region."
