DUBAI, United Arab Emirates (AP) — The United States attacked Iran early Sunday morning over an Iranian strike on a vessel in the Strait of Hormuz that set the container ship ablaze and forced its crew to abandon it. Iran responded with attacks targeting several countries in the Middle East, including Bahrain, Kuwait, Qatar, Oman and Jordan.

The burst of fighting raised new questions about efforts to reach a permanent end to a war that began on Feb. 28. The strait, a key transit route for oil and natural gas, has become the key sticking point in negotiations, and repeated fighting over the past week has left negotiations in danger of collapse.

The U.S. military’s Central Command said it hit some 140 targets in Sunday’s strikes and went after missile and drone launch sites, ammunition dumps, communication equipment and other sites. It said the attacks, heavier than previous attacks in recent days, would weaken Iran’s ability to threaten civilian shipping.

“Iran made a poor choice. Now they pay,” U.S. Defense Secretary Pete Hegseth wrote online.

Semiofficial Iranian news agencies reported that a navy officer was killed by the early morning attack. Iran retaliated by attacking nations in the region hosting U.S. military forces, while insisting it alone must control the strait and potentially charge vessels for traveling through it.

“The era of one-sided deals is OVER,” Mohammad Bagher Qalibaf, the speaker of Iran’s parliament and a main negotiator, wrote Sunday. “We told you: keep your word or pay the price. Reality is knocking.”

Iran and the U.S. agreed to an interim ceasefire on June 17, beginning a 60-day period aimed at reaching a permanent end to the war, which U.S. President Donald Trump declared “over” three days ago.

Negotiations have been repeatedly disrupted by violence. The U.S. has launched three rounds of airstrikes targeting Iran in the last week over Iranian attacks on ships heading through the strait using a route seeking to avoid the Islamic Republic’s territorial waters.
