The European Union's diplomatic chief Federica Mogherini on Thursday insisted the Iran nuclear deal "is working", as US President Donald Trump mulls reimposing sanctions on Tehran.

"The deal is working, it is delivering on its main goal which means keeping the Iranian nuclear programme in check and under close surveillance," Mogherini said after talks in Brussels with Iranian Foreign Minister Mohammad Javad Zarif and his British, French and German counterparts.
