Senior Palestinian leaders will meet in Ramallah on Sunday to debate responses to US President Donald Trump's controversial recognition of Jerusalem as Israel's capital.
Among the options to be considered is the potential suspension of the Palestinian Liberation Organisation's (PLO) recognition of Israel, delegates said.
The two-day meeting of the Palestinian Central Council will begin late Sunday, with Palestinian president Mahmud Abbas expected to open with a brief address.
The 121-member council is a high-ranking arm of the PLO, the internationally recognised representative of the Palestinian people, and includes members of different parties.
Trump's December 6 recognition of Jerusalem as Israel's capital has infuriated the Palestinian leadership, who see at least the eastern part of the city as the capital of a future state they have sought to gain through American-led negotiations.
His administration has also not publicly committed to the idea of an independent Palestinian state, and the PLO office in Washington was briefly closed down.
Abbas has said after the recognition the Americans can no longer play a role as mediator, and is expected to shun Trump's Vice President Mike Pence when he visits Israel on January 22-23.
Ahmed Majdalani, a senior PLO official, told AFP that a committee created to formulate responses to Trump's announcement would recommend redefining the Palestinian relationship with Israel.
Among the options, he said, was suspending recognition of Israel, accusing Israel of failing to abide by agreements.
"It is not possible for the Palestinian side to remain the only one committed to the agreements signed while the other side (Israel) is not committed to them and has violated them for years," Majdalani said.
Previous Palestinian threats to suspend security coordination or recognition of Israel have not been carried out.
In 2015 the council voted to end security cooperation with Israel but it was not implemented, with the rulings not binding on Abbas.
The Palestinian leadership signed the Oslo Accords with Israel in 1993, formalising its recognition of Israel.
The agreements were supposed to lead to a final settlement -- what many envisioned as the creation of an independent Palestinian state -- within five years, but they have since broken down.
Majdalani said instead of US-mediated talks they would be looking for a conference led by the United Nations on the future of the peace process.
The agenda of Sunday's talks includes a review of the situation since Oslo, as well as responses to Trump.
Palestinian Islamist movements Hamas and Islamic Jihad, which are not members of the PCC, have been invited, delegates said, but it was unclear if they would attend.
Nour Odeh, a Palestinian political analyst, said the Palestinian leadership was seeking to change course.
But she said there were different camps among the leadership.
"One that sees that Trump has ushered in a completely different era and business as usual is no longer possible.
"The other camp is less convinced the world is ready to support us in a way that confronts this administration.
"The debate is about what can we do that won't leave us alone with our backs against the wall."
