The U.S. reimposed a naval blockade on Iran and intensified its airstrike campaign Wednesday in retaliation for Tehran’s attacks on ships trying to pass through the Strait of Hormuz. The American strikes hit an Iranian army barracks, killed at least seven troops and wounded hundreds of people across the country, Iranian officials said.
Days of back-and-forth strikes by the U.S. and Iran across the Middle East — and renewed threats to the waterway crucial to global energy supplies — have shredded the interim deal to end the conflict and the region could tip back into all-out war.
The U.S. first imposed a blockade in April and lifted it last month after signing the interim deal that paused the fighting and set a 60-day period for negotiations over issues such as Iran’s nuclear program. Those talks have stalled as fighting over the Strait of Hormuz has intensified.
When the U.S. and Israel launched the war on Iran on Feb. 28, Tehran effectively closed the waterway to shipping traffic — a move that sent the price of oil, fertilizer and many other goods soaring far beyond the region and gave Iran major leverage in negotiations. Those rising prices pose a particular challenge to U.S. President Donald Trump and his Republican Party, which hopes to retain control of Congress in elections in November. But Washington has struggled to successfully reopen the waterway.
About 24 hours after the blockade went into effect, the U.S. military opened fire and disabled a merchant vessel.
Iran’s parliament speaker and lead negotiator, Mohammad Bagher Qalibaf, said Iran was prepared for a fuller military confrontation if the U.S. does not live up to the terms of the interim deal, and Iran’s paramilitary Revolutionary Guard threatened to halt all energy exports from the Middle East over the blockade.
“The export of oil and gas from the region will be either for everyone or for no one,” the Guard said.
Soon after the U.S. launched its third wave of strikes in 24 hours, Trump said Iran was ready to strike a peace deal, but he did not elaborate.
“They don’t like what we’re doing, and they do want to settle. We’ll find out whether or not we settle with them, or we just finish it off,” he said Wednesday at a defense summit at the U.S. Army War College in Pennsylvania.
Later Wednesday, Trump said on social media that Tehran made a “gesture of Goodwill” by releasing an American citizen wrongly detained in Iran since 2024. He didn’t release further details. Human rights lawyer Jared Genser released a statement identifying the detainee as his client Dena Karari, a U.S.-Iranian citizen who runs a nonprofit and was charged with espionage.
Both the US and Iran launch attacks as the blockade is reimposed
The U.S. carried out a wave of strikes, hitting dozens of targets overnight, the military’s Central Command said Wednesday, and then resumed striking Iran during daylight — an unusual move that further signaled the increasing tempo of the attacks. Another wave of strikes began late Wednesday.
U.S. Central Command said it spotted Curacao-flagged oil tanker Belma sailing toward Kharg Island and, after the ship “ignored multiple warnings,” a U.S. aircraft disabled the merchant vessel by firing hellfire missiles into the ship’s smokestack.
In addition to the now-disabled Belma, the U.S. military said it had to speak with two other commercial vessels, but they complied with their instructions to turn away.
Among the U.S. military’s targets was Greater Tunb Island, which is viewed as a strategic point in the Strait of Hormuz. Central Command said the attack targeted Iranian defense and missile sites.
Another strike targeted a barracks for Iran’s 388th Mechanized Infantry Brigade, which operates tanks and armored vehicles, in Sistan and Baluchestan province, Iranian state television reported. The report said Americans fired at least 13 missiles in the attack and the seven dead included conscripts and career soldiers. A number of troops were wounded.
More than 35 people have been killed and more than 300 wounded by U.S. airstrikes in recent days, said Hossein Kermanpour, a spokesperson for the Iranian Health Ministry. Kermanpour did not break down the figures between civilians and combatants.
The announcement marked the first overall toll given by Iranian authorities for this round of fighting. The number of wounded was far larger than for any other recent violence between Iran and the U.S. The army said it would make “a decisive response,” according to state TV.
U.S. Navy Adm. Brad Cooper, who leads Central Command, said in a statement that Iran had launched dozens of missiles and drones at neighboring Gulf Arab countries.
