An attack by Yemen’s Houthi rebels on a British cargo ship in the Red Sea has triggered fears of an “environmental disaster” due to a massive oil slick and raised concerns about further disruptions to trade and food supplies. The Houthis, claiming to respond to Israel’s offensive in Gaza, have struck multiple targets including the ship, US warships, and an Israeli vessel, prompting retaliatory US airstrikes. The escalating conflict, marked by Houthi recruitment of new fighters and claims of advanced weapons like “submarine weapons,” threatens regional stability and poses challenges for addressing the environmental risks and humanitarian crisis in Yemen.
