DUBAI, United Arab Emirates (AP) — The U.S. carried out another round of strikes on Iran on Wednesday, hours after President Donald Trump said that recent Iranian attacks on ships in the Strait of Hormuz signaled the end of the ceasefire.

Military officials said in a social media post that the strikes were intended to “further degrade” Iran’s ability “to threaten freedom of navigation” in the strait.

The action comes just a day after the U.S. military hit a variety of military sites and port facilities following Iran’s targeting of several merchant vessels off the coast of Oman.

The social media post said that the U.S. “is holding Iran accountable for recent unjustified aggression against commercial shipping and civilian crews freely navigating a vital international waterway.”

Iranian state media reported explosions in several locations, including the port city of Bandar Abbas on the strait, Sirik, another southern coastal city, and Bushehr, home to Iran’s nuclear power plant complex.

A day earlier, Iranian state television said eight members of the Army’s air and naval forces were killed in Bandar Abbas and Bushehr.

Trump threatened to ‘hit them hard again’

Earlier in the day, Trump said the U.S. would “probably hit them hard again tonight” and later added that the latest back-and-forth fighting would not result in “long-term” military action.

“Anything that happens is going to happen very fast,” Trump said, though he also suggested the U.S. military might “just finish the job.”

A day after assaults on commercial shipping escalated into an exchange of strikes on Iranian and U.S. military targets, Trump also renewed his past threats to hit Iran’s civilian infrastructure, including electric plants and desalinization plants, and to seize the oil-production hub of Kharg Island.

Speaking on the sidelines of a NATO summit in Ankara, Turkey, Trump said the strikes are continued retaliation for Iranian attacks on commercial ships in the Strait of Hormuz.

“They are behaving very badly,” he said of Iran, accusing the country of launching drones and a missile at ships. After three tankers were hit Tuesday, the U.S. launched strikes on Iran, and Iranian forces retaliated by attacking American military sites in the Persian Gulf.

Iran has asserted that the interim ceasefire deal gives it the right to manage traffic through the strait. Parliament Speaker Mohammad Bagher Qalibaf, a key negotiator in talks seeking a permanent end to the war, was defiant in a post on X: “The era of bullying and extortion is over. It leads nowhere. We don’t fold.”

The exchange of fire raised fears that the war in Iran could reignite, and Trump fueled those concerns by saying the interim agreement to pause fighting was “over,” although he added that he would allow negotiations to continue.

Attacks have repeatedly threatened the shaky ceasefire, but Trump’s comments added new uncertainty, and oil prices shot up after he spoke. A renewed conflict could engulf the wider Middle East and would likely again halt energy shipments through the strait that are crucial to the global economy.

“For me, I think it’s over,” Trump said when asked about the status of the ceasefire. He added that U.S. representatives can continue negotiations, but he cast doubt on the outcome. “They can talk, but I think they’re wasting their time,” he said.

Iranian Deputy Foreign Minister Kazem Gharibabadi, also a top negotiator, retorted on X that Trump’s remarks “are not a sign of power but an admission of the failure” of U.S. policy toward Iran.

Negotiations to reach a final deal had been due to start after the dayslong funeral for Iran’s Supreme Leader Ayatollah Ali Khamenei, who was killed Feb. 28 in the war’s first moments. The funeral was supposed to be a period of lower tensions.
