United Nations: Israel should stop building settlements, denying Palestinian development and designating land for exclusive Israeli use that Palestinians seek for a future state, the Middle East peace "Quartet" recommended on Friday in a an eagerly awaited report.
The report by the Quartet entities sponsoring the stalled peace process - the United States, Russia, the European Union and the United Nations - said the Israeli policy "is steadily eroding the viability of the two-state solution."
"This raises legitimate questions about Israel's long-term intentions, which are compounded by the statements of some Israeli ministers that there should never be a Palestinian state," according to the report.
The day before Israeli elections in March 2015, Prime Minister Benjamin Netanyahu said there would never be a Palestinian state on his watch, only to reverse himself days later and recommit to the objective of a two-state solution.
Diplomatic sources said the report carries significant political weight as it has the backing of close Israeli ally the United States, which has struggled to revive the peace talks amid tensions between Netanyahu and US President Barack Obama.
Relations between the rightist Israeli leader and the Democratic president have yet to recover from their feud over last year's US-led international nuclear deal with Israel's foe Iran.
The Quartet report said Israel had taken for its exclusive use some 70 per cent of Area C, which makes up 60 per cent of the occupied West Bank and includes the majority of agricultural lands, natural resources and land reserves.
"The transfer of greater powers and responsibilities to Palestinian civil authority in Area C, contemplated by commitments in prior agreements, has effectively been stopped and in some ways reversed and should be resumed to advance the two state solution and prevent a one state reality from taking hold," the report said.
The report said at least 570,000 Israelis are living in the settlements, which most countries deem illegal. "Israel should cease the policy of settlement construction and expansion, designating land for exclusive Israeli use and denying Palestinian development," the report recommends.
It said only one permit for Palestinian housing construction in Area C was reportedly approved in 2014, while there did not appear to have been any approved in 2015.
The Palestinians want an independent state in the West Bank, Gaza and Occupied East Jerusalem - areas Israel captured in a 1967 war.
The last round of peace talks broke down in April 2014 and Israeli-Palestinian violence has surged in recent months.
