(CNN)-- Iran's Revolutionary Guards have threatened to cut more energy export routes from the Middle East, in response to the US military reimposing a naval blockade on ships heading to and from Iranian ports.

The Revolutionary Guards said on Wednesday (one day after the blockade was resumed) that the United States should "expect the closure of other oil and gas export routes that serve the interests of the United States and its allies."

It added: 'Either oil and gas exports from the region are available to everyone, or they will not be available to anyone.'

The Revolutionary Guards had announced over the weekend the closure of the Strait of Hormuz, through which a fifth of the world's oil and liquefied natural gas supplies passed before the outbreak of war. Although Saudi Arabia - the world's largest crude oil exporter - has diverted most of its exports to the Red Sea, the presence of Iranian-backed Houthi rebels near the Bab el-Mandeb Strait (at its southern entrance) raises the risk of further disruptions to global energy supplies if the group attempts to target navigation there.

US Central Command said in a post on platform 'X' that the naval blockade imposed by the US military on ships heading to and from Iranian ports was resumed at 4:00 PM Eastern Time on Tuesday.

It is worth noting that the United States had previously imposed a blockade on Iranian ports early in the war that lasted for about two months, specifically between April and June; the blockade operations extended from the Middle East region to the Indian Ocean, thousands of miles away.
