An oil processing facility in Abqaiq was set ablaze, Saturday, following a drone attack claimed by Houthi militants.
Footage shows flames rising high as well as thick plumes of black smoke billowing from what's reported to be the site of the attack.
Fires were also reported at the Khurais oil field in the wake of a second drone attack. Both facilities belong to the state-owned company Aramco, reports say.
Houthi militants operating in Yemen have claimed responsibility for both attacks.
