Palestinians watch on a large screen the speech of Palestinian President Mahmoud Abbas in the 70th session of the United Nations General Assembly, in the West Bank city of Nablus September 30, 2015. Palestinian President Mahmoud Abbas on Wednesday accused Israel of sabotaging U.S. efforts to broker peace and said that Israeli security operations at the Al-Aqsa mosque in Jerusalem could lead to a religious war. In an address to the United Nations General Assembly ahead of a ceremony for the raising of the Palestinian flag at U.N. headquarters in New York, Abbas said that the Palestinian Authority no longer considered itself bound by the accords signed with Israel in the mid-1990s.
