In a statement announced today, Al-Othaimeen affirmed that this attack is a terrorist, subversive and coward act, stressing that the attacks on the vital facilities do not only target the Kingdom of Saudi Arabia, but they also affect energy supplies' security and stability in the world, and constitute a threat to the civilians' lives. He reiterated his call on the international community to stand with the Kingdom of Saudi Arabia in taking practically deterring measures against all terrorist groups that carry out and support such subversive and treacherous acts.
