Rival Palestinian factions Hamas and Fatah will join forces Tuesday in a rare meeting in the West Bank city of Ramallah against US President Donald Trumps long-awaited Middle East peace plan, officials said. "We invited the Hamas movement to attend the emergency meeting of the leadership and they will take part in the meeting," senior Palestinian official Azzam al-Ahmed said. Hamas official Nasser al-Din al-Shaar confirmed he would attend the meeting, which all Palestinian factions were invited to. "The meeting will discuss the position that must be taken (against) Trumps plan," Shaar said. The rulers of Gaza have been at odds with president Mahmud Abbass Fatah movement for years, with Hamas representatives rarely taking part in meetings of the West Bank-based Palestinian leadership. Trump was due to release his plan, years in the works, at the White House later Tuesday together with his close ally Israeli Prime Minister Benjamin Netanyahu -- but Palestinians, who accuse Trump of pro-Israel bias, were not taking part in the Washington event. Trump, however, claimed not only that the plan might "have a chance," but said it could benefit the Palestinians, who he predicted might come around to the idea. "Its very good for them, in fact its overly good for them," the US president told reporters on Monday. "We think we will have ultimately the support of the Palestinians." The Palestinians meanwhile have urged world powers to reject Trumps plan. "We call on the international community to not be partners in this (plan) because it contravenes international law," Palestinian prime minister Mohammed Shtayyeh said on Monday. - Protests planned - The details of Trumps initiative, which has been in the works since 2017, are not yet public. But his administration has already recognized Israeli sovereignty over the Golan Heights, which the Jewish state captured from Syria in the Six-Day War of 1967 and stopped referring to the West Bank as "occupied" territory. It also no longer considers Israeli settlements there as inconsistent with international law, and most analysts expect Trumps peace proposal to reaffirm his administrations positions. Trump also broke with decades of international consensus that the fate of Jerusalem should be negotiated between the parties when he recognized the disputed city as Israels capital in December 2017. The release of the plan comes as Trump faces impeachment hearings over abuse of office. Netanyahu is facing imminent trial proceedings, after dropping his request for parliamentary immunity from corruption charges in a surprise move Tuesday. "This is a plan to protect Trump from impeachment and protect Netanyahu from prison," Shtayyeh told a cabinet meeting Monday. "It is not a Middle East peace plan." Palestinian president Mahmud Abbas has rejected repeated attempts by Trump to discuss the plan, with a senior Palestinian official telling AFP there would be no discussion with the US "until they recognize the two-state solution". Some have speculated that the US proposal could pull back from supporting the creation of a Palestinian state with its capital in east Jerusalem, the common definition of the two-state solution. The chief Palestinian envoy to Britain, Husam Zomlot, said on Tuesday that Trumps Middle East peace plan effectively gives green light to Israel to establish an apartheid state. "This is a political circus, its a sad piece of political theatre," he said, who previously served as head of the Palestinian mission to Washington and as strategic advisor to Abbas. Zomlot said the peace proposal would have none of the characteristics of a true state and would leave the Israelis able to carve up Palestinian territory into "bantustans". "Its a Mickey Mouse state," Reuters quoted him as saying. "Its the Bantustan-ization of the people of Palestine and the land of Palestine," said Zomlot, referring to the creation of quasi-independent homelands for blacks in South Africa that helped the white rulers to enforce an apartheid state. "At noon today, Trump will push Israel and Netanyahu over the cliff into apartheid," he said. "January 28th, 2020, will mark the official legal stamp of approval from the United States for Israel to implement a fully-fledged apartheid system. "History will mark the name of Trump as the one who pushed Israel in the wrong direction," he said. A series of Palestinian protests are planned in both the West Bank and Gaza on Tuesday and Wednesday. -Israeli settlers object to plan- The main political body representing Israeli settlers is coming out against Trumps peace plan because it reportedly includes the formation of a Palestinian state. Yesha Council Chairman David Alhayani said in a statement Tuesday ahead of the peace plans unveiling that settler leaders were "very disturbed" after meeting with American officials in Washington. He says: "We cannot agree to a plan that includes the formation of a Palestinian state that will constitute a threat to the state of Israel and a greater threat in the future." He is calling on Netanyahu to reject any plan that includes the creation of a Palestinian state. Most of the international community supports a two-state solution to the conflict and views the settlements as illegal and an obstacle to peace. More than 600,000 Israeli Jews live in settlements scattered across the occupied West Bank and annexed east Jerusalem. The Israeli military is deploying security reinforcements in the occupied West Bank ahead of the release of the Trump administrations Mideast peace plan. The military said Tuesday it has decided to "reinforce the Jordan Valley area with infantry troops."
