Israeli, U.S. officials take off to UAE

Even before discussions start in Abu Dhabi, the delegates will have made aviation history by taking an Israeli commercial airliner directly from Tel Aviv to the UAE capital over Saudi territory.

"That's what peace for peace looks like," Netanyahu tweeted, 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 Aug. 13, 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.
