The White House says Task Force Iron Gate, the US effort to cut Iran's land and Caspian Sea supply routes, is now operating. US Central Command announced the task force on Saturday 7 November.
A White House post on X on 9 November said "Task Force Iron Gate is in full force and effect in the Islamic Republic of Iran", Gulf News reports.
Donald Trump said, "We're trying to end the war in Iran, and we're doing well because, you know, all we have to do, we're choking it off." Al Jazeera also reports Trump saying the land blockade is in effect.
Trump claims the US naval blockade has severely restricted the movement of goods into and out of Iran. That claim has not been independently checked.
