Palestinian Authority says US peace efforts 'doomed to fail'

US efforts to resolve the Israeli-Palestinian conflict are "doomed to fail," the Palestinian Authority, which has frozen contacts with Washington because of its perceived bias, said on Saturday.

PA spokesman Nabil Abu Rudeina told reporters that a regional tour next week by White House adviser Jared Kushner and US President Donald Trump's special envoy for the Middle East, Jason Greenblatt, would produce "no results".

According to Israeli media, they will visit Israel, Egypt and Saudi Arabia to discuss efforts to present a peace plan. The trip will not include any meetings with Palestinian officials, Haaretz reported on it website.

"Without respect for Arab summit resolutions and those of the UN Security Council... and especially without the accord of the Palestinian people... [US peace efforts] will be doomed to fail and will destabilise the region," Abu Rudeina said.

Trump’s administration is engaged in an internal discussion over the timing and method of initiating its peace plan, concerned their proposals may be dead on arrival if launched under unfavourable circumstances, the Jerusalem Post reported on its website.

Israeli government officials originally anticipated the US plan would land this summer, but White House officials have not yet settled on that time frame and may delay its rollout into the fall or even beyond if necessary, the Post reported.

The Palestinians reacted furiously to Trump's announcement in December recognising Jerusalem as Israel's capital and moving his country's embassy there from Tel Aviv.

They consider East Jerusalem their future capital, insisting the future of the disputed city is an issue to be negotiated between the Israelis and Palestinians.

The US embassy was opened on 14 May, one day before the Palestinians commemorate their mass displacement in the 1948 war surrounding the creation of Israel, which Palestinians refer to as the Nakba (catastrophe).
