Iran said on 9 September that it had attacked 10 vessels near the Strait of Hormuz after the United States sank five Iranian oil tankers, marking the largest wave of attacks on shipping by either side since the six-month-old war began.
Iran has warned vessels operating in the Strait of Hormuz against using routes that are not approved by its maritime authorities, saying ships outside the designated framework will not receive safety guarantees or related protections.
