Iran launched a fierce attack on Persian Gulf oil and gas facilities Wednesday — hours after its gas field complex, the largest in the world, was hit by an Israeli airstrike.

Qatar’s state oil giant QatarEnergy said it suffered “extensive damage” at its Ras Laffan Industrial City after Iranian missiles hit the fuel plant.

“Emergency response teams were deployed immediately to contain the resulting fires,” the world’s second-largest liquefied natural gas exporter said in a statement. ⁠

Saudi Arabia’s Defense Ministry said it intercepted at least four ballistic missiles over Riyadh and destroyed another two Iranian drones before they reached a gas facility in the country’s eastern province.

Falling debris from the interceptions wounded at least four people, Saudi officials added.

Qatar’s Ministry of Foreign Affairs slammed the attacks as “a dangerous escalation” in the Middle East as Iran targets American allies in its retaliatory attacks.

“The Iranian side continues its escalatory policies that are pushing the region toward the brink and drawing countries not party to this crisis into the conflict zone,” the ministry warned.

“The ministry also reiterates that the State of Qatar reserves its right to respond in accordance with Article (51) of the United Nations Charter and the right to self-defense as guaranteed by international law, stressing that it will not hesitate to take all necessary measures to protect its sovereignty, security, and the safety of its citizens and residents,” officials added.

The UAE also reportedly suspended operations at two Abu Dhabi natural gas sites  – the Habshan gas facilities and the Bab field – following Iranian strikes that were intercepted.

The production halt was caused by falling shrapnel, though no injuries were reported.

Iran had directly warned civilians in Qatar and Saudi Arabia to evacuate from energy facilities on Wednesday following an attack on its South Pars gas field, which is jointly operated by Tehran and Doha

The attack damaged Iran’s Asaluyeh refinery, halting production at two of the field’s refineries, which typically put out about 100 million cubic meters of gas a day, according to state media.

Wednesday marks the first major attacks on energy facilities across the Middle East, an escalation that threatens oil and gas prices across the world.

Brent crude oil futures soared to nearly $111 per barrel in the wake of the strikes, after opening on Wednesday at around $101.

European natural gas prices have also surged by more than 6% on Monday.
