The United States launched its fourth round of strikes against the Yemeni Houthis, the first since redesignating them as a terrorist organization.

The strikes were launched against 14 different missile launching sites, according to U.S. Central Command. The strikes were launched hours after the Houthis hit a U.S.-owned merchant ship with the shipping company Genco. None were injured on the ship, and it continued with its mission with some damage sustained.
