Iranian drone strikes have destroyed a number of US HIMARS missile launcher systems in Kuwait, Fars news agency has reported. The outlet also said that three American officers were killed and several others wounded – a claim that has not been confirmed by US Central Command (CENTCOM).

On Sunday, Axios journalist Barak Ravid reported, citing an unnamed US official, that Washington had carried out “a few strikes on missile and air defense systems,” as well as on Iranian Navy small boats, at several locations around the Strait of Hormuz.

Iran’s Press TV reported multiple explosions near Qeshm Island, sharing footage appearing to show smoke rising over the area. Qeshm is Iran’s largest island in the Persian Gulf and reportedly a key site for the country’s coastal defenses, radar systems, and naval assets.

Later in the day, Fars reported that Iranian forces had used drones to destroy the HIMARS launchers in Kuwait, which it said had been readied to fire on Iranian territory. The agency also said three ballistic missiles were fired toward Kuwait’s Al Mina area and a site housing a US ATACMS missile system, adding that US military assets in Bahrain, Qatar, Jordan, and Oman had also been targeted throughout the day.

Kuwait’s military confirmed that the country had come under attack but made no mention of the HIMARS claim or any American casualties, without pinning the blame on Iran. It said that three land border posts in the country’s north had been struck in a “criminal aggressive attack” that caused “material damage,” while a hostile drone hit an offshore drilling platform operated by the Kuwait Oil Company, injuring one worker.

Iran and the US military continue to trade blows after the collapse of a tentative ceasefire earlier this month. Washington accused Tehran of attacking vessels in the Strait of Hormuz, while Iran said that some of the ships had failed to comply with instructions as they passed through. Tehran has since declared the strait closed – a claim US officials dispute, saying commercial traffic continues to move through the waterway.
