Mahmoud Abbas suspends relations with the US, Israel
Abbas said the peace plan unveiled by US President Donald Trump on Tuesday was in "violation of the (autonomy) accords" launched in Oslo in 1993 by Israel and the Palestinians.
Israel will have to "bear responsibility as an occupying power" for the Palestinian territories, he told an emergency Arab League meeting in Cairo.
The US plan would grant the Palestinians limited self-rule in parts of the occupied West Bank, while allowing Israel to annex all its settlements there and keep nearly all of east Jerusalem.
The summit of Arab foreign ministers in Cairo was requested by the Palestinians, who responded angrily to the American proposal.
Abbas said that he told Israel and the US that "there will be no relations with them, including the security ties" following the deal that Palestinians say heavily favours Israel.
The Palestinian leader said that he had refused to take US President Donald Trump's phone calls and messages "because I know that he would use that to say he consulted us".
"I will never accept this solution," Abbas said. "I will not have it recorded in my history that I have sold Jerusalem."
He said the Palestinians remain committed to ending the Israeli occupation and establishing a state with its capital in east Jerusalem.
Abbas said that the Palestinians reject the US as a sole mediator in any negotiations with Israel. He said they would go to the United Nations Security Council and other world and regional organisations to "explain our position".
There was no immediate comment from US or Israeli officials.
'An unjust solution'
The Arab League's head, Ahmed Aboul-Gheit, said the proposal revealed a "sharp turn" in the long-standing US foreign policy regarding the Israeli-Palestinian conflict.
"This turn does not help achieve peace and a just solution," he declared.
Aboul-Gheit said that the Palestinians reject the proposal. He called for the two sides, the Israelis and the Palestinians, to negotiate to reach a "satisfactory solution for both of them".
President Trump unveiled the long-awaited proposal on Tuesday in Washington.
It would allow Israel to annex all its West Bank settlements - which the Palestinians and most of the international community view as illegal - as well as the Jordan Valley, which accounts for roughly a fourth of the West Bank.

In return, the Palestinians would be granted statehood in Gaza, scattered chunks of the West Bank and some neighbourhoods on the outskirts of Jerusalem, all linked together by a new network of roads, bridges and tunnels.
Israel would control the state's borders and airspace and maintain overall security authority. Critics of the plan say this would rob Palestinian statehood of any meaning.
The plan would abolish the right of return for Palestinian refugees displaced by the 1948 war and their descendants, a key Palestinian demand. The entire agreement would be contingent on Gaza's Hamas rulers and other armed groups disarming, something they have always adamantly rejected.
Ambassadors from the United Arab Emirates, Bahrain and Oman attended the Tuesday unveiling in Washington, in a tacit sign of support for the US initiative.
Saudi Arabia and Egypt, Arab states that are close US allies, said they appreciated Trump's efforts and called for renewed negotiations without commenting on the plan's content.
Egypt urged in a statement Israelis and Palestinians to "carefully study" the plan. It said it favours a solution that restores all the "legitimate rights" of the Palestinian people through establishing an "independent and sovereign state on the occupied Palestinian territories".
The Egyptian statement did not mention the long-held Arab demand of east Jerusalem as a capital to the future Palestinian state, as Cairo usually has its statements related to the Palestinian-Israeli conflict.
Jordan, meanwhile, warned against any Israeli "annexation of Palestinian lands" and reaffirmed its commitment to the creation of a Palestinian state along the 1967 lines, which would include all the West Bank and Israeli-annexed east Jerusalem.
Jordan and Egypt are the only two Arab countries that have peace treaties with Israel.
