Palestinian President Mahmoud Abbas pledged at the United Nations on Thursday to work with U.S. President Donald Trump, Saudi Arabia, France and the United Nations on a peace plan for Gaza overwhelmingly backed by the world body.

The 193-member U.N. General Assembly overwhelmingly endorsed this month a seven-page declaration that aims to advance a two-state solution for Israel and the Palestinians and end the Gaza war between Israel and Hamas militants.

The declaration emerged from an international conference at the U.N. in July — hosted by Saudi Arabia and France — on the decadeslong conflict. The United States and Israel boycotted the event and have rejected the international efforts.
