Iranian state media said new video from the Strait of Hormuz showed ships transiting the strategic waterway with Tehran's permission, describing the passage as remaining under strict Iranian control after authorities returned it to what was described as a wartime footing.
Video posted to Telegram by Iran's Fars News Agency showed ships passing through the Strait of Hormuz after obtaining permission from Tehran to transit into the Persian Gulf.
Fars said the footage confirmed that the Strait of Hormuz remains under strict Iranian control.
According to the report, ships entered a "safe corridor" designed by the Islamic Revolutionary Guard Corps Navy. Fars said the route passes between Larak and Qeshm islands and exits south of Larak, close to the Iranian coastline.
The report said passage through the corridor required permission from Tehran.
CNN said it was unable to independently verify the claims about the ships' passage.
The U.S. has imposed a blockade order that applies to all Iranian ports, both inside and outside of the strait.
After Iran's foreign minister declared the waterway open on Friday, the Islamic Revolutionary Guard Corps reversed the decision and reimposed the chokehold it has held on the passage since the war broke out, according to the report.
Fars reported that Tehran has now "returned the Strait of Hormuz to a wartime footing," fully closing it to all vessels without Iranian authorization and prohibiting the passage of military vessels.
The report described the Strait of Hormuz as a critical passage for the global energy trade.
