Yemen’s 12-year-old civil war escalated sharply on September 10, 2026, when Iran-backed Houthi fighters swept down the country’s west coast and seized the strategic port city of Mocha. The rapid offensive, which unfolded within hours after a four-year ceasefire unravelled, allowed the group to take control of approximately 2,100 square miles of territory, according to ABC News.
Houthis Seize Mocha in Rapid Offensive Along Yemen’s Red Sea Coast
The assault began at dawn on Thursday, September 10, catching residents by surprise. According to local fisherman Ali Al-Ahdal, fighters from Ansar Allah poured into the city center as government forces and the National Resistance withdrew south toward Dhubab District. The offensive followed weeks of escalating hostilities, including Houthi missile and drone strikes that damaged port facilities in August, as well as breakthroughs at Jabal al-Nar and the Khalid bin Al-Walid Camp, Yemen’s second-largest military base (Al Jazeera, Ynetnews).
A Houthi field commander identifying himself by the nom de guerre Abu Rajeh stated that the operation relied on surprise and comprehensive coordination between drone strikes and infantry advances. Conversely, an anonymous military officer in the internationally recognized government attributed the setback to unprecedented firepower and missile strikes.
Control of the Bab al-Mandeb Strait and Regional Shipping Impacts
The capture of Mocha places the Houthis in command of territory overlooking the Bab al-Mandeb Strait, a vital shipping corridor connecting the Red Sea to the Gulf of Aden (Al Jazeera, Yahoo News). Analysts note that the waterway handles roughly 10 percent to 12 percent of international maritime trade (ABC News).
The Houthis also claimed control of strategic Red Sea islands, including Perim Island at the southern entrance of the waterway and the Hanish Islands to the north (ABC News). While Houthi military spokesperson Yahya Saree stated that maritime navigation remains safe for all companies except for Saudi vessels—under a blockade announced in July—analysts warn that the group is now positioned to disrupt regional shipping more seriously (ABC News). The disruption has contributed to rising oil prices amid fears of supply delays (Yahoo News, ABC News).
Intense Fighting Spreads to Taiz, Marib, and Al-Jawf
Beyond the coast, intense ground battles have erupted across multiple regions, including Taiz, Marib, al-Jawf, and Dhalea, leaving at least 194 people dead and 880 wounded over a two-week period, according to aid agencies (Al Jazeera).
Taiz, Yemen’s third-biggest city and cultural capital, remains heavily contested. Government forces hold the city center while Houthi positions hem it in from the north and east, with fierce clashes reported on the western approaches (Yahoo News). Meanwhile, pro-government troops and Houthi fighters are engaged in high-stakes combat in Marib—a government stronghold containing critical oil and gas infrastructure—and adjacent al-Jawf (Al Jazeera).
Humanitarian Toll and Saudi Strikes
United Nations officials and non-governmental organizations have cautioned that the resurgent conflict threatens to worsen the country’s humanitarian crisis (ABC News). In response to the Houthi advances and cross-border attacks on Saudi infrastructure—including strikes that suspended oil loading operations at Yanbu and damaged the East-West Pipeline—Riyadh has directed hundreds of airstrikes onto Houthi positions (ABC News). However, many analysts remain doubtful that pro-government forces can successfully roll back the Houthi gains (ABC News).
