France urged the US Congress on Saturday not to rip up the Iran nuclear deal, after President Donald Trump decertified Iran's compliance with the 2015 agreement.

"We strongly hope that Congress, which is now responsible for a possible rupture, does not jeopardise the deal," French Foreign Minister Jean-Yves Le Drian said in an interview with AFP.

"If we denounce a deal that has been respected, it will set a dangerous precedent," particularly in the context of negotiations with North Korea, Le Drian said, echoing other signatories of the Iran deal Britain, France, Germany, China and Russia. 

"For us, the Vienna accord is a good accord, it limits nuclear proliferation and prevents Iran from acquiring atomic weapons. It is robust and coherent," said Le Drian.
