"Initial estimates indicate that the attack was carried out by a drone and did not result in any damage," the ministry said in a statement posted on X. On Monday, some operations at the Ras Tanura refinery were halted following an attack that caused a fire at the complex. The Ras Tanura facility along the kingdom's eastern Gulf coast is home to one of the largest refineries in the entire Middle East and a cornerstone of the kingdom's energy sector. The complex has a capacity of 550,000 barrels per day.
