A missile struck Saudi Aramco’s largest oil refinery at Ras Tanura on Wednesday, according to reports. It remains unclear which part of the complex was damaged. The refinery had been temporarily shut down on Monday following a drone attack.

Monday’s incident had led to accusations against Iran, but Tehran denied involvement, stating that it only targets facilities linked to U.S. and Israeli interests. Iranian officials claimed that Israel carried out a “disguised attack” on the Aramco site instead.

The renewed strike adds to regional tensions surrounding energy infrastructure in the Gulf, though the extent of the latest damage and potential impact on operations were not immediately known.
