Houthi forces seize Bab al-Mandab coast as drone strike halts Saudi pipeline

Coastal offensive and strait closure

Houthi forces in Yemen took control of the country's entire Red Sea coastline following a rapid military advance. Rebel units captured the port city of Mocha on Thursday, followed by the capture of Perim Island on Friday. Perim Island sits directly in the Bab al-Mandab strait, dividing the waterway that measures roughly 20 kilometres across at its narrowest point. Yemeni government officials confirmed that the group controls all islands in the strait, placing the maritime corridor under direct rebel interdiction. The Institute for the Study of War reported that establishing a secure commercial shipping corridor through the narrow passage will be difficult under rebel fire.

Drone strikes on Saudi pipeline infrastructure

Simultaneously, drone strikes launched from Iraqi territory targeted Saudi Arabia's East-West Pipeline, damaging Pumping Station 11 and injuring several people. The installation pumps crude oil across the Hejaz mountains along the conduit connecting Persian Gulf fields to the Red Sea port of Yanbu. The Saudi Energy Ministry announced a precautionary shutdown of the pipeline on Friday following the strike, while the Foreign Ministry confirmed the Iraqi origin of the unmanned aircraft. Satellite imagery from 12 September showed soot deposits and extreme dryness indicators across the installation. On Saturday, Iraqi security forces discovered drone launch apparatuses near the Iranian border. ARD correspondent Ramin Sina described the operational pressure facing the Kingdom.

Basically, Saudi Arabia is under pressure. There have been many attacks. It is becoming increasingly difficult for Saudi Arabia to export oil.

Trade disruption and market fallout

The simultaneous disruption of the East-West Pipeline and the Bab al-Mandab strait compounds existing shipping closures in the Strait of Hormuz, which normally handles approximately 20% of global energy trade. Saudi Arabia produces around 10 million barrels of crude per day and exports 7 million barrels daily. Ship tracking data from Vortexa indicates that crude loadings at Yanbu had risen from roughly 0.8 million barrels per day in late February to 4.6 million barrels daily by late March as exports diverted away from Hormuz. Daily maritime traffic through the Bab al-Mandab corridor dropped from a pre-offensive average of 47 vessels to 37 vessels per day. Crude oil prices climbed back above $100 per barrel following the dual infrastructure disruptions.

Strategic friction and international reactions

The rapid offensive coincided with operational friction between allied forces in the region. Sources connected to Yemeni forces reported to CNN that requests for United States military intervention and Saudi air support went unfulfilled during the rebel advance on the coast. US President Donald Trump stated that Iran was probably responsible for the drone strike on the pipeline, while noting that Houthi fighters sought to keep the United States out of the Yemeni theater. Security expert Frank Umbach stated that the coordinated actions by Iran-backed groups threaten to choke the Saudi economy, presenting severe risks for international trade routes to Europe and East Asia.
