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.

The package's 80 measures will include cuts to the value-added tax on gas and fuel, which could lower prices at the pump by up to 30 cents per litre, he told a news conference after an emergency cabinet meeting.

Sanchez also said the government would cap the maximum price of butane and propane.

The government will also slash electricity taxes by 60 percent, suspend a production tax and reduce the value-added tax on electricity to 10 percent from 21 percent.
