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

Despite IRGC claims to the contrary, the “Strait of Hormuz is open to all vessels seeking to lawfully transit the international waterway,” U.S. Central Command (CENTCOM) said in a post on X Sunday morning.

"U.S. forces are positioned and prepared to ensure that freedom of navigation remains available despite unwarranted Iranian aggression, harassment, threats, and arbitrary declarations. Iran does not control the strait,” the post reads. "Traffic is flowing.”

The Joint Maritime Information Center also says the Strait of Hormuz is open but maintains the regional threat level as “severe” as traffic has continued to flow at a trickle in recent days.

The Islamic Revolutionary Guard Corps' navy announced Saturday that the Strait of Hormuz will be closed until further notice and claimed a commercial vessel transiting the waterway was hit and "halted" by a "warning shot" it fired, according to Iranian media.

The statement also said that any U.S. or allied response would be met by "severe" retaliation.

At least five Middle Eastern states reported fresh attacks on Saturday night and Sunday morning as fighting again escalated between the U.S. and Iran over the Strait of Hormuz.

Qatar and the United Arab Emirates both reported that their defensive systems intercepted missile attacks. At least three people were injured by falling debris in Qatar, the country's Interior Ministry said in a statement shared on social media.

In Jordan, a government statement said that three missiles "originating from Iranian territory fell early Sunday morning across several locations inside the kingdom. No casualties were reported, and the impact resulted only in minor material damage."

Kuwait's army said its forces intercepted an unspecified aerial threat in the Gulf nation's airspace. In Oman, state media said that sites in the Musandam Governorate were targeted by drones.

In Bahrain, meanwhile, air raid sirens were sounding on Sunday morning but there was no official confirmation of new attacks.

Mohammad Bagher Ghalibaf, the speaker of the Iranian parliament who has served as Tehran's chief negotiator in peace talks, suggested in a post to X on Sunday that the U.S. had failed to honor last month's memorandum of understanding.

"The era of one-sided deals is OVER. We told you: keep your word or pay the price. Reality is knocking.," Ghalibaf wrote, posting a screenshot of the text of the MOU in which Iran committed to arranging safe passage for commercial shipping through the Strait of Hormuz.

Ghalibaf's post came after the U.S. launched a new round of airstrikes on Iranian targets in response to Tehran's attacks on commercial shipping in the Strait of Hormuz.

Iran's Islamic Revolutionary Guard Corps alleged in a statement that was read on state run TV on Saturday that several ships used unapproved routes and ignored warnings from the IRGC Navy.

The IRGC Navy said that the Strait of Hormuz will be closed until further notice and claimed that a commercial vessel transiting the waterway was hit and "halted" by a "warning shot" it fired.

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."
