Assessment

The Houthis hold Yemen's entire Red Sea coast and the Yemeni side of Bab el-Mandeb after taking Mocha on Sept 10 and Perim island on Sept 11, astride a chokepoint carrying roughly 12 percent of global trade, 11 percent of seaborne oil and 8 percent of LNG. The UN Security Council met in emergency session on Sept 15 over the advance along the Red Sea coast and the group's grip near the strait, its second Yemen emergency meeting in a week. Fighting inland continued, with Saudi-backed government forces advancing in western Taiz on Sept 14 under Saudi air cover the Houthis put at 54 raids in 24 hours across Lahj, Taiz, al-Jawf, Marib and Hajjah. The UN reported on Sept 15 that more than 125,000 people from over 18,000 households have been displaced since the start of September, and Yemen's internationally recognised prime minister accused the Houthis of killing and displacing civilians during their advance.
