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. “If the United States attacks Iran and the regime falls, Turkey is planning additional measures to reinforce border security,” said the official, who also requested anonymity. Turkey began building a concrete wall in 2021 as concerns grew about a potential influx of migrants following the Taliban’s takeover of Afghanistan. So far, officials say there is no sign of mass movement toward Turkey linked to developments in Iran.
