US forces struck two Iranian launchers on Iran's Larak island on Sunday, a US official said, marking the first known American strikes on Iran since late July.

"I can confirm that earlier today US forces struck two Iranian launchers on Larak Island. Islamic Revolutionary Guard Corps forces were observed preparing to launch rockets with sea mines into the Strait of Hormuz," the official said, Reuters reported.

According to an unnamed US official cited by Al Jazeera Arabic, US forces have bombed the rocket launchers claiming they were preparing to fire missiles carrying naval mines toward the Strait of Hormuz.

Iran's Revolutionary Guards said the attack killed and wounded several soldiers and citizens and would be met with a "response and punishment" from Tehran, Iranian state media reported.

US President Donald Trump ​said last week that all mines ‌had been detonated or removed from the international waters of Hormuz and Iran has been told that any ship ​or boat placing new mines will be ​destroyed.
