The Palestinian Authority is planning to submit a draft resolution to the UN on ending the Israeli occupation by Monday evening, with a view to having the Security Council vote on the text by Wednesday.
The resolution sets out a two-year timetable for Israel to withdraw its forces from the West Bank.
A delegation of Arab leaders will ask the US not to use its veto to block the resolution when they meet US Secretary of State John Kerry in London on Tuesday.
Israeli Prime Minister Benjamin Netanyahu responded on Monday that Israel would “not accept attempts to dictate unilateral moves".
Mr Netanyahu is due to meet Mr Kerry in Rome today.
