Baku, April 16 AZERTAC
The European Union's top diplomat Federica Mogherini arrived in Tehran on her first visit since a nuclear deal between Iran and world powers came into force as tensions surface over its implementation.
Mogherini, who was the lead negotiator for the six powers who struck the deal, was accompanied by other top EU officials.
Her one-day trip comes after Iran raised concerns about banking sanctions, with officials saying the West, particularly the United States, is still creating hurdles to its access to the global financial system.
