Iran live updates: Gulf countries under attack after US completes 3rd round of retaliatory strikes

The Ministry of Defense in Qatar said early on Sunday that the country's armed forces intercepted "a number" of ballistic missile attacks, as the Kuwait Army said it confronted "hostile aerial targets" within its airspace.

Those attacks followed renewed U.S. strikes on Iranian targets, although neither Qatar nor Kuwait detailed where the strikes originated from. Air raid sirens also blared in Bahrain early on Sunday.

"The General Staff of the Army notes that any explosion sounds heard are the result of air defense systems intercepting hostile attacks," the Kuwait Army said in an update.

Kuwaiti forces urged residents to "adhere to security and safety instructions."

Bahrain did not detail a specific threat, but said its air raid sirens were activated.

"The siren has been sounded," Bahrain's Interior Ministry said in a social media post. "Citizens and residents are urged to remain calm and head to the nearest safe place."

U.S. forces completed a third round of strikes on Iran, hitting 140 military targets in retaliation for the attack on a container ship in the Strait of Hormuz earlier Saturday, U.S. Central Command said.

The U.S. struck using "precision munitions" launched by land- and sea-based fighter aircraft, drones and naval vessels, CENTCOM said in a statement posted on social media.

Targets included Iranian missile and drone sites, naval capabilities, ammunition storage facilities, communication networks and coastal surveillance locations, CENTCOM said.

Overall, the U.S. has struck over 300 targets in Iran in three rounds of airstrikes this week, in an effort to "degrade Iran’s ability to attack civilian mariners and commercial vessels freely transiting the strait," CENTCOM said.

In a post on social media in response to U.S. Central Command announcing a third round of strikes on Iran, Defense Secretary Pete Hegseth wrote: "Iran made a poor choice. Now they pay."

The U.S. military launched another set of strikes in Iran Saturday night, U.S. Central Command said in a statement.

The U.S. strikes came after Iranian forces "blatantly attacked M/V GFS Galaxy, a Cyprus-flagged container ship transiting the Strait of Hormuz," CENTCOM said in a statement posted on X.

"A civilian crew member is missing and the vessel is unable to continue the journey due to an onboard fire and significant engineroom damage," CENTCOM said.

"Iran was provided yet another opportunity to demonstrate adherence to the Memorandum of Understanding after being held accountable for earlier attacks on commercial vessels but has again failed," it added.

Iran says the ship was moving through the strait in an "unapproved route" and was hit by a "warning shot."
