RAMALLAH — Palestinian Prime Minister Mohammed Shtayyeh on Monday urged international powers to boycott US President Donald Trump's "peace plan" which they see as biased toward Israel.

"This a plan to protect Trump from impeachment and protect (Israeli Prime Minister Benjamin) Netanyahu from prison. It is not a Middle East peace plan," Shtayyeh told a Cabinet meeting.

"This plan gives Israel sovereignty over Palestinian territory," he said.

Trump is expected to unveil his "peace plan" for the Middle East after hosting Netanyahu and his political rival Benny Gantz in Washington on Monday .

It comes as Trump is facing an impeachment trial in the Senate while Netanyahu, who is facing indictment over corruption allegations, will contest an election next month which Gantz is hoping to win.

"We call on the international community to not be partners in this because it contravenes international law," Shtayyeh told the Palestinian Cabinet.

"The rights of the Palestinian people are not for sale."

The Palestinians have not been invited to Washington, having cut all ties with the Trump administration over its pro-Israel stance.

The plan is widely expected to be the most favourable toward Israel ever proposed by the United States, with alleged leaks — denied by Trump — suggesting it could declare settlements in the occupied West Bank legal.

The US proposal could also pull back from the creation of a Palestinian state with East Jerusalem as its capital after Trump in 2018 recognized occupiedcJerusalem as Israel's capital.

While the US and Israel are likely to be supportive of the plan, the reaction of international powers could be key.

Two European diplomats told AFP the European Union was working on a statement reaffirming its support for the two-state solution along the traditional lines.

Shtayyeh said President Mahmoud Abbas would call a meeting of the Palestinian leadership to discuss the best ways to respond to the plan.

In Gaza on Monday a few hundred Palestinians protested against the Trump plan, which Palestinians ironically call the "Deal of the Century". — AFP
