The Islamic Revolutionary Guard Corps declared the Strait of Hormuz closed "until further notice" and U.S. Central Command said the latest strikes began at 7:15 p.m. ET and marked the third round of U.S. attacks on Iran this week after the IRGC struck a commercial cargo ship that was badly damaged.
The United States attacked Iran into early Sunday morning, setting the container ship ablaze and forcing its crew to abandon it, and Iran apparently responded with strikes targeting Bahrain, Qatar and the United Arab Emirates; the UAE warned the public of an incoming missile and drone attack, Qatar said it intercepted incoming Iranian fire and missile alerts sounded in Bahrain.
The Cyprus-flagged container ship had been traveling in a route hugging the shoreline of Oman, the U.K. Maritime Trade Operations center said, and was unable to continue after suffering significant engine-room damage, a U.S. official and CENTCOM said; one civilian crew member is missing.
CENTCOM had earlier said it launched more than 170 strikes over two days in response to alleged Iranian attacks on commercial shipping and that those strikes targeted Iranian air defenses and missile and drone storage and launch sites along the country's coastline at the mouth of the Strait of Hormuz.
Iranian state media said U.S. attacks apparently targeted Bandar Abbas and Sirik, as well as other areas along the shores of the strait, and offered no immediate information about casualties or damage.
The exchange of attacks widened beyond Iran's borders: Kuwait's military said falling debris wounded one person as it shot down three ballistic missiles, a cruise missile and 10 drones, and Jordanian government spokesperson Mohammad al-Momani said all incoming fire from Iran had been intercepted.
State media and the IRGC said U.S. strikes hit bridges, with state reports saying a railway bridge in Golestan province was struck and the IRGC saying two bridges were attacked on the route to Mashhad; state media also reported explosions in several locations, including Bushehr, and quoted local official Ehsan Jahanian as accusing the U.S. of striking near the nuclear power complex around noon, a claim CENTCOM's press release did not mention.
Diplomatic efforts continued: Iranian Foreign Minister Abbas Araghchi held telephone calls with senior regional officials, including the foreign ministers of Oman, Turkey and Saudi Arabia and Pakistan's army chief, and mediators from Qatar, Pakistan and other nations have been working to revive talks; Oman said it and Iran agreed to keep talking about the Strait of Hormuz at the technical and political levels.
The White House had given Tehran until Saturday to publicly acknowledge the shooting at ships was a mistake and to affirm that the strait would be open, and President Trump directed a negotiating team led by Vice President JD Vance, Jared Kushner, special envoy Steve Witkoff and Secretary of State Marco Rubio to continue talks scheduled in Oman on Saturday.
President Donald Trump suggested the interim deal in the Iran war was "over," and U.S. Defense Secretary Pete Hegseth wrote online: "Iran made a poor choice. Now they pay."
Mostafa Hosseini Khamenei led the funeral prayer as his father was buried in Mashhad, and Supreme Leader Ayatollah Mojtaba Khamenei vowed in his first statement since the funeral that revenge would be carried out, saying, "Such revenge is the will of our nation and must certainly be carried out."
The IRGC said the vessel it struck had been traveling on an unapproved route, had "switched off its systems" and was "brought to a halt," and the corps warned that any retaliation would be met with a "severe response."
U.S. Central Command said its forces carried out a round of strikes that hit at least 140 targets, including missile and drone sites, naval capabilities, ammunition depots, communication networks and surveillance locations.
The U.K. Maritime Trade Operations agency said the container ship was nine nautical miles east of Oman and that damage to the rear of the vessel caused a fire onboard.
The IRGC said it had struck and disabled a second vessel in the strait and that it targeted the U.S. air base at Al Udeid in Qatar with ballistic missiles, destroying the base's fighter jet maintenance center and its command and control facility, the IRGC said.
The IRGC said the strait was closed "at least until the end of US interference in this region."
A spokesperson for Australian Foreign Minister Penny Wong urged Iran to uphold the ceasefire agreement and to ensure safe passage through the Strait of Hormuz, saying Australia wanted negotiations between the U.S. and Iran to continue and the ceasefire to resume.
Iranian Foreign Minister Abbas Araghchi met Oman's Sayyid Badr Albusaidi in Muscat to exchange views on mechanisms for the safe passage of ships through the strait, Tehran said.
U.S. Central Command said "The United States is imposing a heavy cost by continuing to degrade Iran's ability to attack civilian mariners and commercial ships freely transiting the strait."
The Strait of Hormuz is long considered an international waterway, but Iran has insisted that the strait remain under its control and that it be allowed to charge ships moving through it, a stance it adopted after the war began. The U.S. urges mariners to transit on a southern route through Oman's territorial waters, and about a fifth of all traded oil and natural gas passed through the strait before the war began.
Iran's top diplomat accused the U.S. of violating the interim deal by ending waivers that allowed Iran to sell crude oil on the open market in U.S. dollars, and those waivers were ended by Washington in response to the attacks on ships in the strait.
President Donald Trump wrote on social media early Saturday that "1000 Missiles are Locked and Loaded and aimed at the Islamic Republic of Iran, with thousands of more to immediately follow," and he said the U.S. military would automatically retaliate if he were killed. Such retaliation would have to be ordered by Vice President JD Vance, who would become commander-in-chief if Trump were to be killed.
The strikes in Iran over two days — and prior to the ones in the wake of the warning shot — killed at least 17 people and wounded 115 others, Iranian Health Ministry spokesperson Hossein Kermanpour said.
Mohammad Bagher Ghalibaf, speaker of Iran's parliament, warned the U.S. on Sunday to maintain its end of the interim peace deal "or pay the price," writing on X, "The era of one-sided deals is OVER. We told you: keep your word or pay the price."
U.S. Ambassador to the United Nations Mike Waltz said Sunday that "all options are on the table" and that Iran "is not living up to" the preliminary agreement negotiators reached in June, and he referenced Iranian sites hit in what he called "Midnight Hammer." U.S. Central Command said the latest round of strikes brought the total targets hit over three nights to more than 300, and on Sunday morning CENTCOM said the waterway was open and "traffic is flowing."
