Together with European partners, France has advocated a diplomatic solution to end the conflict between Israel and Iran.

"I called for de-escalation and for Iran to exercise the utmost restraint in this dangerous context to allow a return to the diplomatic path," Macron posted on X.

He said he also told Iran to "renounce nuclear weapons," warning of "the risk of the worst for the entire region".

"This is the only path that leads to peace and security for all," Macron said.

On Sunday, Macron also spoke with the leaders of Saudi Arabia, Oman, the United Arab Emirates and Qatar.

Macron will convene a meeting of France's defence and national security council from 1730 GMT Sunday, the presidency said.

He had said Saturday that France and its European partners planned to step up talks with Iran.

Earlier Sunday, French Foreign Minister Jean-Noel Barrot expressed "concern" over the US air strikes on Iran's nuclear facilities and urged "restraint".

On Friday, British, French, German and EU diplomats held talks in Geneva with Iranian Foreign Minister Abbas Araghchi, a week after Israel started its bombardment of Iranian sites.

They urged Iran to revive diplomatic efforts with the United States to find a solution in the standoff over its nuclear programme.
