Houthis Complete Bab al-Mandeb Seizure; Saudi Pipeline Struck in Coordinated Pressure Campaign

What Happened

Yemen's Houthi movement completed its takeover of the entire Yemeni Red Sea coastline on Friday, September 11, capturing Perim Island — the strategic landmass at the centre of the Bab al-Mandeb Strait that divides its two shipping lanes — alongside the mainland Red Sea coastal town of Dhubab. Saudi-backed Yemeni government forces withdrew from Perim, also known as Mayyun Island, without a protracted battle. The advance followed Thursday's capture of the port city of Mocha. Military spokesman Yahya Saree stated the offensive had expelled Saudi-backed forces from six districts spanning 5,400 square kilometres, leaving hundreds killed, captured, or wounded. Four Yemeni government sources confirmed the developments to Reuters.

The same day, Saudi Arabia confirmed that its East-West crude pipeline had been struck by drones originating from Iraqi territory, triggering a precautionary shutdown. Satellite imagery captured black smoke rising near the pipeline on Thursday. Several people were injured. Iraq's prime minister dismissed the Maysan Operations Commander early Saturday after acknowledging the drones had launched from Iraqi soil, a strike widely attributed to Iran-backed militias. Riyadh said it would hold back on retaliation to allow Baghdad time to act, while reserving the right to respond.

Why It Matters

The Bab al-Mandeb Strait carries roughly twelve percent of global maritime trade. Since Iran effectively closed the Strait of Hormuz to Saudi oil exports in February, the East-West pipeline and the Bab al-Mandeb route have together served as Riyadh's primary export corridors. The Houthi seizure of Perim Island now gives Iran's most capable proxy physical control over both of Saudi Arabia's remaining export options — not the ability to threaten from a distance, but direct dominance over the strait's navigation lanes themselves. The simultaneous pipeline strike from Iraqi territory, attributed to Iran-backed militias, signals a coordinated multi-front campaign designed to compound Saudi Arabia's vulnerability without triggering a single declared act of war.

For the Gulf region, the compounding is significant: tighter Red Sea lanes mean higher freight costs and insurance premiums already elevated by years of Houthi maritime activity. For the UAE specifically, the scenario accelerates pressure on alternative energy routing, sharpens the case for domestic energy security investments, and raises the risk of broader regional escalation at a moment when Gulf states face constrained retaliatory options. The next pressure point to watch is whether Baghdad's dismissal of its military commander satisfies Riyadh, and whether Saudi Arabia's pipeline remains offline beyond precautionary timelines.
