Saudi Arabia has warned Israel that annexing the West Bank is a red line and could prevent normalization under the Abraham Accords, N12 reported on Sunday.
The Gulf States' warnings came ahead of the United Nations General Assembly vote to recognize a Palestinian state and the French-Saudi implementation of the plan.
“Annexation steps will have major implications on all levels,” Saudi messages sent to Israel said, as reported by N12.
Saudi political sources reportedly told Israeli officials that they were willing to use several economic and security-related means to enforce Riyadh's opposition, and would even close its airspace to Israel.
N12 reported that Israeli annexation of the West Bank would also harm Washington's relationship with Arab countries.
UK, Canada, Portugal, and Australia recognize Palestinian state
The report came after the UK, Canada, and Australia all moved to recognize a Palestinian state.
Prime Minister Benjamin Netanyahu stated that he would not respond to the trilateral recognition until after his return from the US. He is expected to discuss the matter when he meets with US President Donald Trump at the White House on Monday.
Other than Saudi Arabia, the United Arab Emirates has signalled that it could downgrade diplomatic ties with Israel if Israel annexes part or all of the West Bank, Reuters reported on Thursday.
Abu Dhabi warned Netanyahu's right-wing coalition this month that any annexation of the West Bank would be a "red line" for the Gulf state, but did not say what measures could follow.
The UAE, which established ties with Israel in 2020 under the Abraham Accords, was considering withdrawing its ambassador in any response, the sources told Reuters.
The sources, who all spoke on condition of anonymity, said Abu Dhabi was not considering completely severing ties, although tensions have mounted during the almost two-year-old Gaza War.
A source in Israel said the government believed it could repair its strained ties with the UAE, a major commercial center seen as the most significant of the Arab states to establish ties with Israel in 2020. The others were Bahrain and Morocco.
