Kuwait Petroleum Corporation (KPC) has announced that one of its oil facilities had been hit in "repeated Iranian attacks", causing significant damage and some injuries, according to the state news agency KUNA.

Kuwait's armed forces said they had intercepted Iranian ballistic missiles and drones ​early on Saturday, adding that a number of firefighters and oil sector workers had been injured while responding to the attacks.

Iran said it was responding to US attacks on bridges, ​power facilities and other infrastructure.

US airstrikes early on Saturday killed three people and wounded eight others in the southern Hormozgan province, which borders the Strait ​of Hormuz, while two bridges and a road tunnel were damaged, Iran TV reported.

Iran's Health Ministry said that 50 people had ​been killed and more than 500 injured in US strikes on the country over the past three weeks, reported Reuters.

"Since there is no international institution to prevent the savagery of the U.S. military, we have no path before us except the ⁠Quranic command: ‘Whoever attacks you, attack them in the same manner'," the IRGC said in a statement warning US allies in the region to expect more strikes.

The US carried out further airstrikes in the same province on Saturday afternoon, the semi-official Fars news agency said, quoting provincial authorities, but there were no reports of civilian casualties.
