Thursday’s drone strikes turned one of Saudi Arabia’s most important energy safeguards into its latest vulnerability. Drones launched from Iraq hit the East-West crude pipeline in the Riyadh and Medina regions, sparking fires, causing damage and injuring several people, Saudi authorities said.¹

The timing matters. The roughly 750-mile Petroline system carries crude from Abqaiq on the Gulf coast to Yanbu on the Red Sea, allowing the kingdom to bypass the Strait of Hormuz — precisely as fighting between the United States and Iran has made that waterway more perilous. Its estimated design capacity is 7 million barrels a day, making it far more than a backup route.²

On Friday, Riyadh shut the line as a precaution and dispatched emergency teams to secure it and assess its condition. The Energy Ministry offered no timetable for a restart, saying: “Any further developments will be announced in due course.”¹ Saudi Arabia’s diplomatic posture was initially restrained as well: the Foreign Ministry said it would refrain from retaliation for now, giving the Iraqi government time to prevent further attacks from its territory.¹

By Sunday, satellite images gave the closure a stark visual dimension, showing fire-damaged structures and broad blackened areas around a pumping station.² The damage reinforced fears that the kingdom’s export options are being constricted from both directions.

To the east lies Hormuz, where regional conflict has sharpened supply risk. To the west, Iran-backed Houthi forces have increased attacks on Saudi targets and moved toward the Bab el-Mandeb Strait, the southern Red Sea chokepoint. That leaves Riyadh confronting a grim irony: the pipeline designed to escape one maritime bottleneck has become vulnerable while another is under mounting pressure.¹ Oil markets have already registered the danger, with Brent rising above $108 a barrel Monday after gaining more than 20% over the previous month.²
