DHAHRAN, Saudi Arabia (AP) – A fire erupted at an oil refinery in Eastern Saudi Arabia Wednesday killing one employee before it was extinguished, Saudi Aramco, the company that owns the complex said in a statement.

The blaze at Ras Tanura complex, north of Dhahran on the eastern coast of the Gulf Country, broke out at 4:50 a.m. local time (0150 GMT) and was brought under control in an hour, the statement from the Saudi Arabian Oil Co. said. An accidental hydrocarbon leak that led to the accident was under investigation.

Aramco said the incident did not interrupt operations at the refinery complex.
