The Ras Laffan industrial complex sustained damage after a missile attack on Wednesday, QatarEnergy said.
"Emergency response teams were deployed immediately to contain the resulting fires, as extensive damage has been caused," QatarEnergy said. Qatar's interior ministry attributed the attack to Iran and said that it has "gained preliminary control over the fire at Ras Laffan, with no reported injuries".
Tehran earlier on Wednesday listed the 305,000 b/d Ras Laffan refinery in Qatar among five downstream facilities it said it would attack shortly in retaliation for what it described as US-Israeli strikes on Iranian gas treatment plants at the South Pars gas field.
It was not immediately clear whether the refinery or the nearby 77mn t/yr LNG export terminal were directly attacked or sustained any damage.
Tehran also threatened strikes against the 400,000 b/d Samref refinery at Yanbu and the Sadara petrochemical complex at Jubail in Saudi Arabia, Qatar Chemical in Doha and the Al-Hosn sour gas field in Abu Dhabi.
Saudi Arabia also came under attack on Wednesday night local time, according to the Saudi defense ministry. "Part of an intercepted ballistic missile" fell near a refinery located south of Riyadh, the ministry said. It also reported intercepting drones aimed at an unnamed gas facility in the country's east.
