Araghchi reaches Oman for fresh discussions
The development comes as Iranian Foreign Minister Abbas Araghchi arrived in Muscat for talks with Omani officials.
According to the semi-official Tasnim news agency, the discussions will focus on the Strait of Hormuz and maritime security. Iranian state news agency IRNA quoted Foreign Ministry spokesperson Esmaeil Baghaei as saying the visit is “a continuation of the consultations that we started with Oman over the past one or two months”, with shipping safety expected to be a key topic.
The Strait of Hormuz has remained at the centre of regional tensions following attacks on commercial vessels and growing concerns over freedom of navigation.
