President Donald Trump warned that if Yemen’s Houthi rebels enforce a blockade in the Red Sea, the United States will take action, citing past U.S. strikes against the group. The Houthis had threatened to block Red Sea shipping in response to regional tensions, including actions related to Gaza, and control a chokepoint vital to global trade via the Bab al-Mandeb. Trump said the Houthis have faced no lasting problems with the United States and warned of a potential new conflict front that could disrupt critical shipping lanes and energy supplies. The comments align with earlier U.S. and regional assessments of the threat within a broader Iran-linked conflict. Several reports describe the blockade as a significant escalation with the potential to widen the Iran war and affect Gulf and world energy markets. The developments come amid ongoing tensions involving Yemen, Iran, and Saudi Arabia, with various actors engaging in retaliatory or threatened actions.
