A map published by Iran's newly-created "Persian Gulf Strait Authority" claims "Iranian armed forces oversight" across more than 22,000 sq km (8,800 sq miles).

It extends into the territorial waters of Oman and the UAE. The UAE described Iran's claims of control as "nothing but fragments of dreams".

Iran's new authority added that all transit through the strait "requires coordination with and authorization from the Persian Gulf Strait Authority".

The US and Gulf allies have repeatedly rejected Iranian attempts to assert control over the strait. The US has told ships not to comply with Iran's rules.
