President Trump has redesignated Yemen’s Houthi movement as a terrorist organization. The move reverses Biden’s removal of the terrorist label in February 2021 and reinstates the label first imposed by Trump’s then-Secretary of State Mike Pompeo as the first Trump administration was preparing to leave office. Houthi fighters have attacked cargo ships in the Red Sea and fired projectiles at Israel amid Israel’s war on Gaza. As in 2021, aid groups warn the U.S. terrorist designation could increase the humanitarian crises of hunger and illness in Yemen.
