LONDON, March 18 (Reuters) - Saudi Arabia's state oil giant Aramco 2223.SE restarted its Ras Tanura oil refinery on March 13, having shut down the plant on March 2 following a drone attack, industry monitor IIR said.
Ras Tanura, with a crude processing capacity of 550,000 barrels per day, is the biggest oil refinery in Saudi Arabia.
Saudi Aramco did not immediately respond to a request for comment.
