ABU DHABI, March 10 (Xinhua) -- The Ruwais oil refinery, considered the largest single-site refinery in the Middle East and among the top four largest in the world, has been closed as part of precautionary measures following a drone attack, Bloomberg reported Tuesday.
Earlier in the day, authorities in Abu Dhabi said a fire broke out at a facility in the Ruwais industrial complex after a drone attack, with no injuries reported so far.
There was no immediate report on whether the refinery itself, situated in the complex, was hit. ■
