Iran has reportedly instructed the Houthis to prepare to block the Red Sea's Bab el-Mandeb gateway in the event of a US strike on its power infrastructure. This potential blockade could disrupt shipping in the region. The specifics of the situation and the likelihood of such a blockade are unclear, with some outlets suggesting it is a possible response to a US attack, while others imply it is part of a broader warning by Iran regarding potential retaliation against western targets.
