President Donald Trump said on September 12 that Iran was probably responsible for drone strikes that hit Saudi Arabia's East-West pipeline two days earlier. The September 10 attacks targeted pump stations in the Riyadh and Medina regions, causing injuries and significant infrastructure damage and prompting Saudi Arabia to shut the pipeline as a precaution. The 1,200-kilometer route connects Saudi oil fields in the east with Red Sea export terminals and normally carries an estimated 4% to 5% of global oil supply. Investigators traced the drones' launch point to Iraq's Maysan province near Iran's border. Iraq dismissed the local military operations commander responsible for the area but did not retaliate further, after Riyadh reportedly urged Baghdad to avoid escalation. The pipeline had become especially important because ongoing hostilities had effectively closed the Strait of Hormuz, which normally handles roughly a fifth of global petroleum consumption. Brent crude briefly reached about $110 per barrel after the strikes. A prolonged outage could tighten supply and extend price gains, with higher crude costs feeding into gasoline, shipping and consumer inflation.
