Saudi Aramco has shut down its 400,000-barrel-per-day Jizan oil refinery in Saudi Arabia following an attack by Yemen’s Houthis on Saturday, a note from consultancy firm IIR, seen by Reuters, shows.

The attack damaged the plant’s Integrated Gasification Combined Cycle complex and the tank farm area, the note says, adding that Aramco will tentatively complete repairs and restart the plant by August 15.

Aramco has not immediately replied to a Reuters request for comment.
