Iraq said its prime minister ordered an investigation after Saudi Arabia attributed the East-West pipeline strikes to drones originating from Iraq. [S2]

Saudi Arabia said it temporarily shut the pipeline as a precaution after multiple attacks in the Riyadh and Medina regions. [S1][S2][S3]

The reported September 10 attacks caused fires, material damage and injuries. [S1][S2][S3][S4]

Reporting on responsibility evolved: Middle East Eye said Saudi Arabia had not identified a responsible party and cited CNN for the Iraqi origin, while Al Jazeera reported a Saudi Foreign Ministry statement that the drones originated from Iraq. [S2][S3]

Reported satellite imagery supports a physical incident near the pipeline route but does not independently establish who operated the drones. [S2][S3]

Verification result: verified, because none of the 350 points of material-claim weight is contradicted and two independent reporting families directly support the central claim. [S1][S2]

The pipeline carries crude toward the Red Sea as a route around the Strait of Hormuz, making its shutdown material to energy security. [S1][S3][S4]
