commentary
Yemen's Iran-backed Houthi militants have taken control of the city and seaport of Mocha, as well as much of the Red Sea shoreline near the Bab el-Mandeb strait. The Strait of Hormuz is already largely closed, and this development has led to a significant increase in oil prices, with a barrel now costing $109. The US has reportedly sent over 100 military advisors to Saudi Arabia as part of a new joint forces command to help the Saudis counter Houthi attacks. The disruption to global trade has also caused diesel fuel prices to skyrocket, reaching an all-time high of $6 per gallon in the US, which is expected to have a ripple effect on supply chain costs and household expenses.

Story summary
Houthis captured the Red Sea port city of Mokha, near Bab al-Mandeb Strait, on September 10-11, 2024, after a week-long offensive. The seizure intensified fighting along Yemen’s western coast, with government forces retaliating by launching airstrikes and artillery strikes against Houthi positions. Government spokesperson Majed Abdullah al-Nazili confirmed the Houthis' control over Mokha and surrounding areas, including key roads. This move gives the Houthis strategic leverage over a crucial shipping route that handles about 25% of daily petroleum shipments worldwide. The capture also threatens to isolate Gulf oil-producing countries from their main shipping routes through Bab al-Mandeb Strait, similar to Iran's closure of the Strait of Hormuz. Yemen’s internationally recognized government is struggling to counter this advance, with civilians in Mokha fleeing to Aden for safety.

The Yemeni government told Reuters that Iran’s Revolutionary Guard Corps (IRGC) have guided the Houthi advance, and according to Zachary Cohen, Katie Bo Lillis, and Kylie Atwood of CNN, U.S. officials think that hundreds of IRGC officers are currently in Yemen working with the Houthis to shut down the Bab el-Mandeb.
