Palestinian leader Mahmud Abbas said Thursday there could be no peace in the Middle East without a two-state solution, sending a warning as Saudi Arabia considers recognizing Israel.

"Those who think that peace can prevail in the Middle East without the Palestinian people enjoying their full, legitimate national rights would be mistaken," Abbas told the UN General Assembly.

The veteran 87-year-old leader made a new appeal to UN Secretary-General Antonio Guterres to call an international conference on creating a Palestinian state.

The United States, historically the peace broker between the two sides, has all but given up on serious negotiations with Israeli Prime Minister Benjamin Netanyahu's hard-right government, which has pushed forward settlements in the occupied West Bank considered illegal internationally.

A UN conference "may be the last opportunity to salvage the two-state solution and to prevent the situation from deteriorating more seriously and threatening the security and stability of our region and the entire world," Abbas said.

His address came a day after Netanyahu discussed Saudi normalization in a meeting with US President Joe Biden.

Saudi Arabia's de facto ruler, Crown Prince Mohammed bin Salman, said that the process was getting "closer."

Israel and the United States believe that the Jewish state's normalization with Saudi Arabia -- guardian of Islam's two holiest sites -- would be a game-changer for the Middle East.

But the Saudi prince, in an interview with Fox News, said that the kingdom wanted progress on the Palestinian issue before establishing ties.

Israel has normalized relations with five Arab states -- three of them in 2020 including the United Arab Emirates, which said its decision persuaded Netanyahu to drop a plan for West Bank annexation.

But Netanyahu returned to power in December with a coalition that includes extreme-right and ultra-Orthodox parties which has vowed to strengthen settlements.

An Israeli diplomat walked out of the General Assembly as Abbas denounced the "apartheid" policies by Israel, a characterization that angers the Jewish state.

"Its racist, terrorist settlers continue to intimidate and kill our people, to destroy homes and property, to steal our money and resources," Abbas said.

"This is done before the very eyes of the world and with complete impunity," he said.

The United States has made no major push on a two-state solution since a failed effort nearly a decade ago by John Kerry, with Donald Trump's administration instead blessing Israeli actions.

President Joe Biden's administration, while returning to a more traditional US position, sees little prospect of diplomatic success.

A Saudi-Israel deal, by contrast, could mark a major foreign policy achievement for Biden on an election year.

Much like the United Arab Emirates with Trump, Saudi Arabia has been seeking sweeteners from Biden in return for recognizing Israel. Saudi Arabia has been seeking security guarantees, reportedly including through a potential treaty.

Gulf Arab nations are united with Israel in their tense relationships with Iran's ruling Shiite clerics.

This month marks three decades since Israel and the Palestinians signed at the White House the Oslo Accords, which established limited self-government under the Palestinian Authority but never led to a lasting solution.

Netanyahu -- who addresses the General Assembly on Friday -- has said that the Middle East's priorities have moved on and hopes normalization with Arab states in effect bypasses a process with the Palestinians.
