A fire broke out at a refinery of Kuwait’s public oil company due to a raid by unmanned aerial vehicles, the official Kuwaiti news agency KUNA reported.

“The Mina Al-Ahmadi refinery, owned by Kuwait National Petroleum Corporation (KNPC), was targeted early this morning by hostile drone attacks that caused fires in some of its units,” according to the agency, following an attack the day before on this infrastructure that had again caused a fire.

In retaliation for a joint attack by the United States and Israel that began on February 28, Tehran has stepped up strikes on the energy infrastructure of Gulf countries in recent days.

Today’s attack on the Mina Al-Ahmadi refinery caused no casualties, but brought about the closure of units at the facility, while firefighters are making efforts to contain the fire, according to the official Kuwaiti news agency.

In other Gulf countries, the United Arab Emirates said today that it was responding to missile and drone attacks, while Bahrain said it had brought a warehouse fire caused by shrapnel from an “Iranian attack” under control.

In Saudi Arabia, the Saudi Defense Minister said that, in the space of two hours, more than a dozen unmanned aerial vehicles were “intercepted and destroyed” in the eastern part of the country and another in the north.
