On 17 January the US military launched a fourth round of missile strikes targeting Houthi-controlled sites in Yemen, aiming to prevent imminent threats to merchant vessels and US Navy ships in the region. These actions come after months of Houthi attacks on ships in the Red Sea, causing disruptions in trade between Asia and Europe. The Houthis, backed by Iran and controlling most of Yemen, claim their actions are in solidarity with Palestinians in Gaza. The Biden administration has now decided to designate them as ‘global terrorists’, reversing a decision made in 2021; however, some commentators felt that Biden was ‘playing with fire’, possibly worsening an already dire humanitarian situation in Yemen. Despite sanctions and previous military operations by US and British forces against the Houthis, they continue to target numerous vessels. The Pentagon press secretary confirmed that the US would persist in taking military action to try to prevent further attacks.
