Israel is working on coordinating plans for a possible military strike with Saudi Arabia, with Riyadh prepared to provide tactical support to Jerusalem, a British newspaper reported early Sunday.

The two countries have both united in worry that the West may come to terms with Iran, easing sanctions and allowing the Islamic Republic to continue its nuclear program.

According to the Sunday Times, Riyadh has agreed to let Israel use its airspace in a military strike on Iran and cooperate over the use of rescue helicopters, tanker planes and drones.

“The Saudis are furious and are willing to give Israel all the help it needs,” an unnamed diplomatic source told the paper.

The report comes as Prime Minister Benjamin Netanyahu is in the midst of a blitz to lobby against a deal and cobble together an international alliance opposed to an agreement that allows Iran to continue enriching uranium.

On Sunday, Israel will welcome French President Francois Hollande, who a week earlier put the kibosh on a deal between six world powers and Iran that would ease sanctions in return for initial steps toward curbing enrichment.

Netanyahu on Friday urged France to remain firm in its pressure on Iran ahead of a new round of talks on the Islamic Republic’s nuclear program in Geneva, kicking off Wednesday.

After meeting Hollande, Netanyahu will head to Moscow on Wednesday to meet with President Vladimir Putin and lobby against the deal.

Iran’s bid for the bomb “threatens directly the future of the Jewish state,” Netanyahu told CNN recently, in a short preview clip of an interview broadcast on Saturday. As the prime minister of Israel, he stressed, he had to care for “the survival of my country.”

CNN reported that Netanyahu also said in the interview that he would do whatever it was necessary to do in order to protect Israel. The full interview will air Sunday morning.

Should a deal be reached at talks set to resume in Geneva on Wednesday, according to the diplomatic source, a military option would be back on the table. Saudi tactical support, in lieu of backup from the Pentagon, would be vital for a long-range mission targeting Iran’s nuclear program.

Saudi Arabia, a Sunni Muslim country across the Persian Gulf from Iran has long been at odds with Tehran, and fears a nuclear weapon would threaten Riyadh and set off a nuclear arms race in the region.
