Palestinian President Mahmoud Abbas on Friday called for United Nations Secretary-General Antonio Guterres to convene an international conference early next year to launch "a genuine peace process" between Israel and the Palestinians.

Abbas urged Guterres to work with the Middle East Quartet of mediators — the United States, Russia, the European Union and the UN — and the UN Security Council on a conference "with full authority and with the participation of all concerned parties, early next year, to engage in a genuine peace process."

The Palestinians want a state in the West Bank and Gaza Strip with east Jerusalem as its capital, all territory captured by Israel in 1967.

Palestinian leaders rejected a peace proposal unveiled in January by US President Donald Trump, in which Washington would recognise Jewish settlements in occupied territory as part of Israel.

"There will be no peace, no security, no stability and no coexistence in our region while this occupation continues and a just, comprehensive solution to the question of Palestine, the core of the conflict, remains denied," Abbas told the 193-member UN General Assembly in a video pre-recorded due to Covid-19.

He said the Palestinians remained committed to the 2002 Arab Peace Initiative in which Arab nations offered to normalise ties with Israel in return for a statehood deal with the Palestinians and full Israeli withdrawal from territory captured in 1967.

The United Arab Emirates and Bahrain signed agreements last week to establish ties with Israel, becoming the first Arab states in a quarter century to break a longstanding taboo.

The Palestinians denounced the move.

Saudi Arabia's King Salman bin Abdulaziz, in his debut speech to the United Nations on Wednesday, said the Arab Peace Initiative is the basis for a "comprehensive and just solution," but also said he supported US peace efforts.

He stopped short of endorsing the recent US-brokered agreements.

Saudi Arabia has quietly acquiesced to the deals but has signalled it is not ready to take similar action.

Abbas also said the Palestinians were "preparing ourselves to hold parliamentary elections, followed by presidential elections" and that all factions and parties would take part.

However he set no date, and there are numerous obstacles.

Abbas's Fatah faction is dominant in the West Bank, but its rival Hamas controls Gaza, and East Jerusalem was captured by Israel in the 1967 Middle East war and later annexed, in a move that has not won international recognition.
