Update: Donald Trump warned over US stance on Jerusalem

Mr Abbas's office said the Palestinian leader warned Mr Trump of dangerous repercussions for Middle East peace efforts, as well as security and stability in the region and the world.

The statement did not say if Mr Trump gave a timeline for the intended move.

US officials familiar with planning for a possible announcement on Jerusalem said they expect Mr Trump to speak on the matter on Wednesday, although the specifics of what he will say were still being debated.

The officials, along with an outside adviser to the administration, said they expected Mr Trump would make a generic statement about Jerusalem's status as the "capital of Israel".

They said they did not expect the president to use the phrase "undivided capital", which would imply Israeli sovereignty over east Jerusalem, which is not recognised by the United Nations.

They also said Mr Trump planned to sign a waiver delaying for another six months a US legal requirement to move the US embassy in Israel from Tel Aviv to Jerusalem.

But they said Mr Trump would probably give wide latitude to David Friedman, the US ambassador to Israel, to make a determination on when such a move would be appropriate.

Mr Friedman has spoken in favour of the move.

As discussions continued on Tuesday, pressure from numerous quarters against full-on recognition of Jerusalem as Israel's capital appeared to have led to the possibility that Mr Trump include comments in his speech that might mitigate the impact of the announcement.

Among the ideas under discussion were Mr Trump giving a nod to Palestinian aspirations to have the capital of an eventual state in east Jerusalem or endorsing the concept of a two-state solution, something he has yet to do. It remained unclear whether any such comments would be included.

Jerusalem is home to the third-holiest shrine of Islam, along with the holiest site in Judaism and major Christian holy sites.

It forms the combustible centre of the Israeli-Arab conflict.

Any perceived harm to Muslim claims to the city has triggered large-scale protests in the past, both in the Holy Land and across the region.

Earlier: Tension building amid question over US stance on Jerusalem

Vociferous Arab and Muslim opposition is building to any possible US recognition of contested Jerusalem as Israel’s capital, as European leaders expressed concern about harm to fragile Middle East peace efforts.

Turkey threatened to cut ties with Israel, the Palestinians warned they would halt contacts with their US counterparts, and key Washington ally Saudi Arabia spoke out strongly against such a possible step.

Saudi Arabia, a regional powerhouse, is crucial to any White House plans to promote a possible Middle East peace deal.

President Donald Trump said he hopes to broker the "ultimate deal", but has not divulged details.

French President Emmanuel Macron said he reminded Mr Trump in a phone call on Monday night that the fate of Jerusalem should be determined in negotiations on setting up a Palestinian state alongside Israel.

Mr Macron said in a statement that he expressed concern about any possible unilateral US moves and that he agreed with Mr Trump "to speak again shortly on this subject".

EU foreign policy chief Federica Mogherini, who was meeting US secretary of state Rex Tillerson in Brussels, said any actions that undermine Middle East peace efforts "must be absolutely avoided".

Mr Trump’s next move concerning Jerusalem remains shrouded in mystery.

US officials have said he may recognise Jerusalem as Israel’s capital this week as a way to offset his likely decision to delay his campaign promise of moving the US embassy there.

Mr Trump’s point-man on the Middle East, son-in-law Jared Kushner, later said the president has not decided yet what steps to take.

Meanwhile, the Trump administration appeared to have missed a statutory deadline to sign a new waiver keeping the US embassy in Israel in Tel Aviv.

The deadline came and went without any White House announcement about whether Mr Trump had signed a waiver.

Without the waiver, by law the embassy is supposed to move to Jerusalem.

At the same time, the prospect of Mr Trump recognising Jerusalem as Israel’s capital has triggered mounting opposition in the Arab and Muslim world.

East Jerusalem, now home to more than 300,000 Palestinians, was captured by Israel in 1967 and then annexed to its capital, a move most of the international community has not recognised.

Palestinians seek east Jerusalem as a future capital.

Israel’s current government, unlike its predecessors, rejects the idea of partition of the city.

Under international consensus and long-standing US policy, the fate of the city is to be determined in Israeli-Palestinian negotiations.

A Trump recognition of Jerusalem as Israel’s capital would upend Washington’s traditional approach to the conflict.

It was not immediately clear what Mr Trump could hope to gain from such a step, while downsides include alienating crucial Arab allies, from Saudi Arabia to Jordan.

On Tuesday, warnings against such a possible US move were pouring in from across the region.

Ahmed Aboul-Gheit, the head of the Arab League, urged the United States to reconsider.

A possible recognition of Jerusalem as Israel’s capital would be a "dangerous measure that would have repercussions" across the region, he said during a Cairo meeting of Arab League representatives gathered to discuss the issue.

Turkish President Recep Tayyip Erdogan told parliament that US recognition of Jerusalem as Israel’s capital was a "red line" and that his country’s response "could go as far as us cutting diplomatic ties with Israel".

Israeli education minister Naftali Bennett played down the threat, saying that "at the end of the day it is better to have a united Jerusalem than Erdogan’s sympathy".

In the West Bank, the diplomatic adviser of Palestinian President Mahmoud Abbas said recognition of Jerusalem as Israel’s capital could end Washington’s role as mediator between Israelis and Palestinians.

"If the Americans recognise Jerusalem as the capital of Israel, then this would mean they decided, on their own, to distance themselves from efforts to make peace and that they will have no credibility or role in this issue," Majdi Khaldi said.

"We will stop our contacts with them (in the event of recognition) because such a step goes against our existence and against the fate of our cause," Mr Khaldi said.

"It targets Muslims and Christians alike."

Palestinian political factions led by Mr Abbas’s Fatah movement called for daily protest marches this week, starting on Wednesday.

Saudi Arabia expressed its "grave and deep concern" about possible recognition.

In a statement on the state-run Saudi Press Agency, the foreign ministry said that the kingdom affirms the rights of Palestinian people regarding Jerusalem, which it said "cannot be changed".

The statement warned that this step would "provoke sentiments of Muslims throughout world".

On Monday, the Organisation for Islamic Co-operation, which has 57 member states, said US recognition of Jerusalem as Israel’s capital would constitute "naked aggression" against the Muslim and Arab world.
