Saudi Arabia shut its East-West oil pipeline as a precaution after it came under multiple attacks in the Riyadh and Medina regions, the Ministry of Energy said in a statement on Friday.
The ministry said that the attacks caused several injuries and that emergency teams are taking steps to secure the pipeline and assess its safety.
The East-West pipeline is a key route for transporting Saudi crude from the Gulf state's eastern oil-producing region to the Red Sea port of Yanbu, allowing exports to bypass the Strait of Hormuz.
The shutdown comes as oil markets face heightened supply risks from escalating attacks and disruptions across the Middle East.
Brent crude surged above $100 per barrel this week, while Saudi crude supply fell to its lowest level in more than three decades in August, according to the International Energy Agency.
Saudi Arabia's Ministry of Energy did not give an estimate of how much oil the pipeline was carrying at the time of the attacks or say how long the shutdown would last.
