A senior adviser to the Leader of the Islamic Revolution has warned that any country cooperating with a US-led blockade against Iran would be committing an “act of war,” stressing that all those involved would bear responsibility for the consequences.

“The aggressors seeking to harm Iran have heard the repercussions of their actions reverberate across the region, Europe and the United States,” Mohammad Mokhber wrote in a post on X on Wednesday.

He further warned that any country cooperating in the illegal blockade would face the repercussions of involvement.

“Today, any form of cooperation in the hostile blockade against Iran constitutes an act of war, one that will be recorded in the historical memory of the Iranian nation. The responsibility and consequences of such actions will fall upon all those involved, irrespective of geographical boundaries.”

Mokhber made the remarks in response to threats by Iran’s adversaries.

On Saturday, the United States Central Command (CENTCOM) announced plans to block Iran’s supply routes across its land borders and the Caspian Sea, expanding its naval blockade of Iranian ports.
