An Iranian missile attack struck Qatar's main refinery on Wednesday, sparking a massive fire.

Qatar’s Ministry of Interior said that civil defense teams are responding to the fire, The Caspian Post reports, citing Al Jazeera.

In a statement, QatarEnergy confirmed that the incident caused “extensive damage” after “missile attacks” targeted Ras Laffan Industrial City, the country’s key energy hub.

“All personnel have been accounted for and no casualties have been reported at this time,” the world’s largest liquefied natural gas (LNG) producer added.

The announcements came hours after Iran threatened to attack oil and gas facilities across the Gulf region in retaliation for an Israeli attacks on its South Pars gasfield as the fallout from the United States-Israeli war on the country continues to escalate.
