Palestinian Prime Minister Mohammed Shtayyeh said his government is resigning, in a move that could open the door to US-backed reforms in the Palestinian Authority. President Mahmoud Abbas must still decide whether he accepts Shtayyeh and his government's resignation, tendered Monday.

But the move signals a willingness by the Western-backed Palestinian leadership to accept shake-up that might usher in reforms seen as necessary to revitalize the Palestinian Authority. The US wants a reformed Palestinian Authority to govern Gaza once the war is over. But many obstacles remain to making that vision a reality.
