Yemen's internationally recognised government (based in Aden after Houthi forces seized the capital Sanaa in 2014) carried out 81 attacks on Houthi positions in a single 24-hour period, while the Houthi movement launched drone strikes on Saudi Arabia's Najran province, claiming hits on the regional airport and an Aramco oil facility. The escalation follows months of intensifying clashes along Yemen's frozen front lines and Houthi-declared naval blockades targeting Saudi infrastructure and Yemeni oil exports. The surge in violence threatens to unravel a UN-brokered truce that had largely halted fighting since 2022, with the UN warning that any return to full-scale conflict would deepen a humanitarian crisis already leaving at least 18 million Yemenis without reliable access to food.
