RIYADH — An oil refinery in Riyadh was attacked by drones at 6:05 a.m. on Friday resulting in a fire that was brought under control, an official spokesman at Saudi Arabia"s Ministry of Energy said in a statement. No one was injured, and oil supplies and petroleum products were not affected by the attack, the statement added. The spokesman called the attack a cowardly act and expressed the Kingdom"s strong condemnation. "Saudi Arabia asserts that such acts of terrorism and sabotage, repeatedly committed against vital installations and civilian facilities — the last of which was the attempt to target the Ras Tanura refinery and Saudi Aramco’s residential area in Dhahran — do not target the Kingdom alone, but more broadly the security and stability of energy supply to the world, as well as the global economy," the statement read. The spokesman renewed the Kingdom"s call to all nations and organizations of the world to stand together against such acts of terrorism and sabotage and to stop all groups carrying out or supporting these attacks.
