oe Biden is to visit the Middle East for the first time as US president, with a trip to Israel, the Palestinian territories and Saudi Arabia.

The tour will take place over four days in July.

Relations between the US allies have been tested since Mr Biden came to office in January 2021.

The White House has criticised Israeli settlements; Palestinians have urged stronger support; and Saudi ties have frayed over the murder of a journalist.

When he was campaigning for the presidency in 2019, Mr Biden vowed to make Saudi Arabia "the pariah that they are" for killing Jamal Khashoggi.

Khashoggi, a dissident Saudi journalist who wrote for the Washington Post, was murdered by Saudi agents inside the kingdom's consulate in Istanbul, Turkey, in 2018 after he was lured there.

US intelligence agencies concluded that Crown Prince Mohammed bin Salman, Saudi Arabia's de facto ruler, had approved an operation to capture or kill Khashoggi.

The prince denied playing any role and Saudi prosecutors blamed "rogue" agents.

Crown Prince Mohammed had a warm relationship with Mr Biden's predecessor, Donald Trump. But soon after Mr Biden took office, the White House said the new president intended to "recalibrate" the relationship with Saudi Arabia.

Rising fuel prices have helped convince the Biden administration that this is not a good time to freeze the Saudis out.

The two men will discuss energy production, notes the BBC's Barbara Plett Usher in Washington, although the president has insisted the decision to visit has more to do with security issues than the price of petrol.

It will mark the first face-to-face meeting between Crown Prince Mohammed and President Biden.

Last week, 13 human rights groups warned it could "embolden the crown prince to commit further violations of international human rights and humanitarian law".

"We urge [the Biden] administration to secure genuine progress on human rights before acting in a manner that would bolster the status of the crown prince and his government," they said.

A senior administration official said human rights and the war in Yemen, where Saudi-backed government forces have been battling the Iran-aligned rebel Houthi movement since 2015, will be on the agenda.

Mr Biden will make history as a US president by flying directly to Saudi Arabia from Israel - a path rarely allowed by Riyadh, which has no diplomatic relations with Israel. The desert kingdom only recently began to permit Israeli commercial flights en route to the UAE to use its airspace. Crown Prince Mohammed has ruled out following the UAE by normalising its relations with Israel before a settlement between Israel and the Palestinians.
