France will expel two Iranian diplomats in response to Iran’s decision to ban two French diplomats from its embassy in Tehran, French Foreign Minister Jean-Noël Barrot said on Tuesday.

“Two Iranian diplomats in France will be expelled in the coming days,” Barrot said in a post on X.

He described Iran’s treatment of the French diplomats as “intolerable,” saying the expulsions were a response to their brief detention in Iran last month.

The French diplomats were arrested over allegations of “interference” before being released, according to Barrot.

The latest move marks a further deterioration in diplomatic relations between France and Iran.
