JERUSALEM (AFP) — Firefighters battled a blaze at a giant oil refinery in Kuwait on Friday after a fresh drone attack as Iran kept up a wave of strikes on its neighbors and vowed there was “no concern” about its missile production.

Despite calls for an end to targeting Gulf energy infrastructure by European leaders on Thursday, Kuwait reported a fire at its Mina Al-Ahmadi refinery, a day after a direct hit on Qatar’s vital Ras Laffan facility.

Iranian authorities had vowed to retaliate after an Israeli strike on Wednesday damaged its South Pars gas field, which draws on the world’s biggest known gas reserve and is vital for domestic supplies.

The escalating damage to Gulf infrastructure has spiked oil and gas prices again and led to fears of lasting damage to global supplies, even as Israeli Prime Minister Benjamin Netanyahu indicated an end to the fighting could be close.

“We are winning and Iran is being decimated,” the Israeli premier said at a press conference on Thursday, claiming Tehran no longer had the capacity to manufacture ballistic missiles.

“This war is ending a lot faster than people think,” he added without providing a specific timeframe.

Iran’s leaders, despite an Israeli assassination campaign and three weeks of bombardment, have vowed to end the conflict on their own terms.

“Our missile industry deserves a perfect score... and there is no concern in this regard, because even under wartime conditions we continue missile production,” Iran’s Revolutionary Guards spokesperson Ali Mohammad Naini was quoted as saying by the Fars news agency.

Moments after his message was shared by the agency, the Revolutionary Guards said he had been killed in United States-Israeli strikes.

Iran retains a stranglehold over the strategic Strait of Hormuz through which a fifth of global oil and liquefied natural gas usually flows.

Iranian state media reported several waves of missiles fired at Israel overnight and Friday morning, with blasts heard over Jerusalem. There were no reports of casualties.

The United Arab Emirates also reported missile attacks, while Saudi Arabia intercepted more than a dozen drones early Friday as Gulf nations began the observation of Eid al-Fitr, the holiday that marks the end of the Islamic fasting month of Ramadan.
