The first direct commercial flight from Israel to the United Arab Emirates has landed in Abu Dhabi, with a US-Israeli delegation on board, after the two countries struck an accord to normalise ties.

Jared Kushner, President Donald Trump's son-in-law and White House advisor, was on board Flight 971 of Israel's national carrier El Al as part of the delegation who were to meet with UAE officials.

The aircraft flew through Saudi Arabia's airspace, according to specialist website FlightRadar24 - the first time El Al has publicly flown over the kingdom.

Mr Kushner was among the top aides to President Trump who joined also joined aides to Israeli Prime Minister Benjamin Netanyahu in flying to the United Arab Emirates today to put the final touches on a pact establishing open relations between the Gulf power and Israel.

Even before discussions start in Abu Dhabi, the delegates made aviation history by taking an Israeli commercial airliner - the word "peace" printed in Arabic, English and Hebrew above a cockpit window of the El Al Boeing 737 – directly from Tel Aviv to the UAE capital over Saudi territory.

"That's what peace for peace looks like," Mr Netanyahu tweeted, hailing what he termed a historic flight and describing a deal for formal ties with an Arab state that does not entail handover of land that Israel captured in a 1967 war.

Announced on 13 August, the 'normalisation' deal is the first such accommodation between an Arab country and Israel in more than 20 years and was catalysed largely by shared fears of Iran.

Palestinians were dismayed by the UAE's move, worried that it would weaken a long-standing pan-Arab position that called for Israeli withdrawal from occupied territory - and acceptance of Palestinian statehood - in return for normal relations with Arab countries.

Mr Trump's senior adviser and son-in-law, Mr Kushner, and national security adviser Robert O'Brien head the US delegation.

The Trump administration has tried to coax other Sunni Arab countries concerned about Iran to engage with Israel. The most powerful of those, Saudi Arabia, has signalled it is not ready.

But in what could presage a more relaxed posture by Riyadh, the El Al plane today will be allowed to overfly Saudi territory to cut flight time.

In the Israeli-occupied West Bank, Hanan Ashrawi, a member of the Palestine Liberation Organisation's executive committee, said Mr Kushner and his team were "scrambling to convince as many Arab and Muslim leaders as possible" to give Mr Trump an election boost.

"They will be a prop at the backdrop of a meaningless spectacle for a ridiculous agreement that will not bring peace to the region," she said.
