Saudi Pipeline Shut, Houthis Near Bab al-Mandeb as Iran War Widens

Saudi Arabia has shut down its 1,200-km East-West oil pipeline — a strategic bypass for the Strait of Hormuz — after drone attacks launched from Iraqi territory triggered fires along the route. Simultaneously, Yemen's Houthi forces have captured the Red Sea port city of Mukha and are reported by eyewitnesses and military sources to be approximately 75 km from the Bab al-Mandeb Strait. Iran's Supreme National Security Council secretary Mohsen Rezaei stated Iran used anti-ship missiles against U.S. ships for the first time, with U.S. CENTCOM making an indirect reference to attacks on two of its vessels. The Iraqi government ordered the closure of the Shalamcheh and Chadaba border crossings with Iran and announced an investigation into the pipeline attack. The BRICS summit in New Delhi issued a call for 'maximum restraint' in the Middle East without specifying enforcement mechanisms.

Why this mattersThe East-West pipeline was Saudi Arabia's only meaningful way to move oil to export markets without transiting the Strait of Hormuz; its shutdown simultaneously raises the value of Hormuz transits and amplifies the threat of Houthi Bab al-Mandeb control into a potential dual-chokepoint scenario that has no modern precedent. For U.S. consumers and markets, both transit routes feeding Asian and European oil trade are now operationally threatened in the same week, with direct U.S. military assets already engaged.
