In the late evening hours of 22 January 2024, the U.S. and U.K. military forces – with the support of Australia, Bahrain, Canada and the Netherlands — conducted airstrikes against at least eight Houthi targets in Yemen. According to U.S. officials, the airstrikes targeted several Houthi-controlled sites — including missile systems, launchers, radars, weapons storage facilities and air defense systems — used to attack merchant vessels and U.S. Navy ships in the region. The strikes were carried out in response to continued actions by the Houthis and were intended to degrade the militant group’s abilities to conduct further attacks in the Red Sea, Bab el-Mandeb Strait and the Gulf of Aden. The latest joint operation follows the initial airstrikes conducted by the U.S. and U.K. military forces on 11 January against at least 60 Houthi targets across 30 sites, as well as several attacks thereafter conducted by the U.S. military.
