French President Emmanuel Macron on Monday spoke to US counterpart Donald Trump and expressed concern about designating Jerusalem as Israel's capital, the Elysee palace said.

"The French president has expressed his concern at the possibility of the United States unilaterally designating Jerusalem as capital of the state of Israel," a statement said, adding that the two leaders had spoken by phone.

Any such decisions must be "within the framework of negotiations between Israelis and Palestinians," it added
