Houthis Declare Naval Blockade of Saudi Arabia

Yemen's Houthi movement announced a blockade on vessels calling at Saudi Arabian ports, effective July 20 at 12:00 UTC, warning that ships trading with the Kingdom could be sanctioned or targeted. The group framed the move as an 'eye for an eye' response to a Saudi-backed strike on Sanaa International Airport's runway a week earlier. The threat was aimed largely at crude exports from Yanbu on the Red Sea, which had become Saudi Arabia's critical relief valve — exporting roughly 4 million barrels/day, up 400% from pre-war levels — after the Strait of Hormuz effectively closed during the Iran war. Multiple VLCCs and container ships rerouted or paused transits through the Bab el-Mandeb Strait in the days that followed.
