US to recognise Jerusalem as Israel's capital in world first
US President Donald Trump will recognise Jerusalem as Israel's capital, senior administration officials have said.
He is due to announce the controversial decision in a speech later.
Mr Trump is also expected to approve moving the US embassy from Tel Aviv to Jerusalem, but not for several years.
Israel welcomes the changes but the Palestinians and Arab leaders have warned they will jeopardise any Middle East peace process.
Saudi Arabia, an ally of the US, called the changes "a flagrant provocation to Muslims".
Israel has always regarded Jerusalem as its capital city, while the Palestinians claim East Jerusalem as the capital of a future Palestinian state.
In recognising Jerusalem as Israel's capital, the US becomes the first country to do so since the foundation of the state in 1948.
What is so contentious about Jerusalem's status?
The issue goes to the heart of Israel's conflict with the Palestinians, who are backed by the Arab and wider Islamic world.
The city is home to key religious sites sacred to Judaism, Islam and Christianity, especially in East Jerusalem.
Israel annexed the sector from Jordan after the 1967 Middle East war and regards the entire city as its indivisible capital.

- Why settlement issue is so difficult
According to the 1993 Israel-Palestinian peace accords, its final status is meant to be discussed in the latter stages of talks.
Israeli sovereignty over Jerusalem has never been recognised internationally and all countries maintain their embassies in Tel Aviv.
Since 1967, Israel has built a dozen settlements, home to about 200,000 Jews, in East Jerusalem. These are considered illegal under international law, though Israel disputes this.
In recognising Jerusalem as Israel's capital, the US could reinforce Israel's position that settlements in the east are valid Israeli communities.
What is the US proposing?
Trump administration officials said recognising Jerusalem as Israel's capital was seen as "a recognition of reality" by the US government.
However, specific boundaries of the city would remain subject to a final status agreement, the official said. The status of holy sites would not be affected.

Mr Trump would also direct the state department to begin the process of moving the US embassy to Jerusalem – but this could take several years as it still has to be designed and built and security concerns would need to be addressed.
He originally promised the move to pro-Israel voters during his campaign for the presidency.
The US officials added that the president would still sign a regular waiver blocking the embassy's move from Tel Aviv to Jerusalem until the new building was completed.
Successive presidents have signed waivers to get round the 1995 Jerusalem Embassy Act, which mandates moving the embassy. They have done this so that the US can be seen as neutral in Middle East peace negotiations.
Mr Trump has vowed to pursue a peace agreement between Israelis and Palestinians, led by his son-in-law and top adviser Jared Kushner.
An administration official said the new US policy on Jerusalem was not designed to favour Israel in that process.
What has world reaction been?
Ahead of his formal announcement, Mr Trump phoned several regional leaders to inform them of the embassy move.
- Saudi Arabia's King Salman bin Abdulaziz al-Saud told Mr Trump the relocation of the embassy or recognition of Jerusalem as Israel's capital "would constitute a flagrant provocation of Muslims, all over the world"
- Palestinian leader Mahmoud Abbas warned of "the dangerous consequences such a decision would have to the peace process and to the peace, security and stability of the region and of the world"
- Hamas leader Ismail Haniya called for a "day of rage" this Friday and said "Palestinian people everywhere [would] not allow this conspiracy to pass"
- Jordan's King Abdullah said the decision would "undermine efforts to resume the peace process"
- Egypt's President Abdul Fattah al-Sisi urged Mr Trump "not to complicate the situation in the region"
- Turkey's President Recep Tayyip Erdogan said his country could sever ties
US government employees and their families have been barred from personal travel in Jerusalem's Old City and the West Bank for security reasons ahead of expected protests.
Israel's intelligence minister Israel Katz told Army Radio that Israel was "preparing for every option", including an outbreak of violence.
France, the European Union and the Arab League have also expressed concern.
No sign it's a bargaining chip
Analysis by Barbara Plett-Usher, state department correspondent, BBC News
By recognising Jerusalem as Israel's capital President Trump is fulfilling a campaign promise. There is no other obvious reason he is doing this now.
Administration officials said he would simply be acknowledging reality – that Jerusalem functions as Israel's capital. They said the decision would not determine final status issues such as boundaries and sovereignty – that is still left to negotiations.
On other core issues of the Israeli-Palestinian conflict, Arab and Muslim leaders may be able to work with changes in the US approach but Jerusalem is also holy land, not just a disputed capital.
Jordan and Saudi Arabia are custodians of Islam's holy sites and have issued strong warnings that this move could inflame the Muslim world.
There is also no indication that this is a bargaining chip to advance the peace process: according to the officials, President Trump is not expected to publicly endorse a two-state solution.
It sounds like the Palestinians will get nothing. Perhaps there is a wider strategy at work but it looks like a workaround so the president can satisfy his pro-Israel voters.
