Saudi Arabia agreed Wednesday to permit UAE flights to "all countries" to overfly the kingdom, as Israeli premier Benjamin Netanyahu signalled more direct flights linking the UAE with the Jewish state.

The announcement comes after the first direct commercial flight from Tel Aviv to Abu Dhabi on Monday, which passed through Saudi airspace, to mark the normalisation of Israel-UAE ties.

Netanyahu, meanwhile, announced that Monday's landmark commercial flight across Saudi Arabia would not be the last.

"Now there is another tremendous breakthrough," he wrote in a statement shortly after the Saudi announcement.

"Israeli planes and those from all countries will be able to fly directly from Israel to Abu Dhabi and Dubai, and back," Netanyahu said, without giving any timeline.

"Flights will be cheaper and shorter, and it will lead to robust tourism and develop our economy," he said.

Saudi Foreign Minister Faisal Bin Farhan insisted that Wednesday's decision does not change the kingdom's "firm and established" position towards the Palestinian issue.

Allowing flights between Israel and the UAE to cross Saudi airspace save long detours around the Arabian peninsula.

President Donald Trump's son-in-law and advisor Jared Kushner, who has led a US push for Gulf states to establish ties with Israel as it seeks to isolate Iran, led an American delegation aboard Monday's flight.
