Drone attacks have set alight two Saudi Aramco oil facilities in Saudi Arabia, with the blazes now said to be under control.

The attacks on Saturday morning were carried out on facilities in Abqaiq and Khurais, according to a tweet from the Saudi Ministry of Interior.

The ministry said that the fires were controlled and that “the competent authorities are investigating”.

Abqaiq is 60 kilometres south-west of Aramco’s headquarters in Dhahran in eastern Saudi Arabia, while Khurais is another 200 kilometres south-west.

No group has yet claimed responsibility for the attacks.

Yemeni Houthis have already been blamed for similar drone attacks on Aramco facilities this year, with two oil pumping stations attacked in mid-May and gas processing facilities in the remote Shaybah field hit in mid-August.
