Turkey will offer to mediate between Washington and Tehran during a visit by Iran's foreign minister on Friday, officials said, as Ankara considers reinforcing security along its border should the dispute escalate. Friday's visit by Iranian Foreign Minister Abbas Araghchi comes after US President Donald Trump threatened a military strike on Iran over its deadly protest crackdown earlier this month. Iran is ready to negotiate on the nuclear file again," Fidan had told Al-Jazeera television. Analysts say Turkey believes a military intervention against Iran would generate serious security risks, including instability and mass migration, and therefore prioritises diplomacy. So far, officials say there is no sign of mass movement toward Turkey linked to developments in Iran.
