DUBAI, July 9 (Reuters) – Iranian armed forces launched attacks on U.S. military infrastructure in Gulf states on Thursday following U.S. strikes on Iran’s southern coastal and eastern provinces, further eroding a three-week-old ceasefire.

Iranian media later reported multiple explosions across southern Iran, including Bushehr, where one of the country’s nuclear plants is located, along with Konarak, Choghadak and Bandar Abbas.

U.S. official said there had been no American strikes in recent hours. The attacks came as Iran buried its slain Supreme Leader Ayatollah Ali Khamenei at a shrine in Mashhad, capping a week of funeral processions and rallies. Khamenei was killed in an airstrike on the first day of the war on February 28, as part of a U.S.-Israeli barrage against Iran that set off a months-long conflict killing thousands and throttling worldwide energy supplies.
