Saudi Arabia said on Wednesday that its armed forces, in coordination with US Central Command (CENTCOM), carried out "targeted strikes" against Iran-backed groups in Iraq that it said were responsible for drone attacks on the kingdom's oil facilities.
CENTCOM said the operation followed more than 30 drone attacks over the previous 72 hours that it said were "directed by Iran's Islamic Revolutionary Guard Corps (IRGC) against US forces and Saudi energy infrastructure".
The Saudi Defence Ministry said the strikes targeted groups in Iraq that it accused of launching attacks on oil facilities in the kingdom's Eastern Province. It said Riyadh was not seeking escalation but would respond to any "aggression".
The announcement of the US-Saudi strikes came a few hours after Saudi Arabia said its air defences intercepted and destroyed several drones launched from Iraq. It was the second such attack in less than two days.
Saudi defence ministry spokesperson Turki al-Malki said on Tuesday the drones were launched by what he described as Iran-backed groups in Iraq, adding Riyadh reserved the right to respond "at the appropriate time and place".
Iraqi Prime Minister Ali al-Zaidi ordered an investigation on Monday into the drone attacks, saying Iraq would not allow its territory to be used to launch attacks against neighbours.
