In response to the American strikes, Iran’s Islamic Revolutionary Guard Corps (IRGC) said the waterway was closed until further notice and launched attacks on US bases and allies in the region.
The IRGC said it had hit a US base in Jordan, while the United Arab Emirates, Qatar, Kuwait and Bahrain all responded to missiles and drones from Iran.
It comes after incidents earlier this week in which three commercial tankers were attacked, prompting an exchange of strikes between the US and Iran.
Earlier on Sunday, state media said Iran had closed the Strait until further notice after firing a naval cruise missile at a vessel that was attempting to sail along an unapproved route.
The Guards said the vessel was “hit by warning shots and stopped” after ignoring repeated instructions, according to a statement carried by the state news agency.
