A crucial Saudi oil pipeline that was struck in an attack will mostly be out of service for weeks as the damage is repaired. That's according to two regional officials. The East-West Pipeline, which runs across the kingdom, is key to Saudi Arabia’s strategy of shifting its oil exports to the Red Sea to avoid the Persian Gulf’s Strait of Hormuz, where Iranian attacks have stifled shipping. An attack that Saudi Arabia blamed on drones from Iranian-backed militias in Iraq forced the shutdown of the pipeline on Thursday. The officials, who have been briefed on the matter, said repairing the damage could take three to five weeks.
