[Iran's Supreme Leader Advisor Warns the U.S. of Potential Mandeb Strait Blockade as Countermeasure] On April 5, Iran's Supreme Leader's foreign affairs advisor, Velayati, warned the U.S. that if it 'makes another mistake,' the resistance front led by Iran might block the Mandeb Strait as a countermeasure. Velayati stated on social media that the Mandeb Strait is as important as the Hormuz Strait, and if the White House takes foolish actions, global energy and trade flows could be disrupted. The Mandeb Strait connects the Red Sea and the Gulf of Aden and is under the control of Yemen's Houthi forces. Some media outlets believe this statement is a response to U.S. President Trump's threats against Iran earlier that day.
