Drone strikes have sparked huge fires at two major oil facilities in Saudi Arabia run by the state-owned company Aramco.
Apocalyptic scenes were caught in footage from Abqaiq, the site of Aramco's largest oil processing plant.
The huge fire engulfed multiple sections of the site, which is the world's largest oil processing plant ad employs a number of Western workers.
The man who filmed the footage, who declined to be identified, said he was woken up by the noise coming from the refinery.
A second drone attack started fires in the Khurais oilfield, which is the country's second largest oilfield.
