US and Iran trade most intense strikes since ceasefire was extended

The US launched airstrikes against Iran overnight on Thursday, killing at least 14 people, while Tehran responded by hitting Gulf countries in the most intense exchange of fire since a shaky ceasefire was extended last month.

The tit-for-tat strikes on Thursday were the largest since Tehran and Washington signed a memorandum of understanding on 17 June aimed at extending the ceasefire and giving space for negotiations for a permanent truce.

Sirens sounded at least three times in Bahrain, where the US navy’s fifth fleet is headquartered, while Iranian missiles also targeted Kuwait and Qatar. There were no immediate reports of any damage.

The attacks came hours after Donald Trump said the memorandum of understanding was “over” because of Iranian attacks on ships in the strait of Hormuz. After the strikes, the US president posted videos of explosions in Iran and threatened the country once again.

“This is in retribution for yesterday’s bombing of ships by Iran. If it happens again, it will get much worse!” Trump wrote on Truth Social. Hours before, he had promised that strikes would not lead to long term fighting but would be “very-fast”.

His comments and the exchange of fire prompted worries that the ceasefire could break down and raised concerns about the long-term prospects of negotiations. Significant gaps remain between the two countries over issues such as Iran’s control over the strait of Hormuz, as well as inspections of nuclear facilities.

Back-and-forth attacks have happened since the MOU was signed, but Thursday’s strikes were the most intense in weeks.

The US military said it hit about 90 targets in Iran, showing footage of strikes on missile launchers and a runway. It said the strikes were meant to degrade Iran’s capacity to “threaten freedom of navigation” in the strait of Hormuz, a critical choke point for about 20% of the world’s oil and gas.

Iran accused the US of war crimes after it said two bridges in the eastern provinces leading to the city of Mashhad were targeted, the city where the late Ayatollah Ali Khamenei was slated to be buried on Thursday. The bridges constitute key infrastructure for Iran’s cross-border trade with China, which has dramatically increased since the US war with Iran started.

Trump has repeatedly threatened to hit bridges, power plants and other civilian infrastructure in Iran. Targeting civilian infrastructure if they are not military objectives could amount to a war crime.

Iranian state media also reported explosions in several cities, including Bushehr, which houses Iran’s nuclear power plant complex. At least three people were killed in Iran’s south-west Khuzestan province, while a firefighter was killed in an airport in the south-eastern city of Iranshahr. Nine members of Iran’s military were also killed in strikes on Wednesday.

The US attacked Iran after Iran struck three ships in the strait of Hormuz on Tuesday. Iran stopped virtually all shipping out of the Strait during the war, sending global energy prices soaring and putting pressure on Trump domestically ahead of midterm elections.

The MOU calls for the reopening of the strait of Hormuz to commercial shipping for 60 days. Iran has said it wants to charge fees to ships that want to transit through the strait, conflicting with the US, which insists that the strait is an international waterway and should not have tolls.

Iran continues to view its control over the strait as an important source of leverage in its negotiations with the US, while Trump appears to view strikes on Iran as a way to increase pressure on Tehran.

Mohammad Bagher Ghalibaf, a senior Iranian negotiator and parliament speaker, said US pressure on Iran would not lead anywhere.

“America still hasn’t learned that bullying and breaking promises are no longer cost-free,” he said in a post on X. “Let me put it plainly: If you strike, you’ll get hit.”

Mediators attempted to de-escalate tensions between the US and Iran in an effort to salvage negotiations. The Qatari prime minister, Sheikh Mohammed bin Abdulrahman Al Thani, a key intermediary between the countries, spoke with Iran’s foreign minister, Abbas Araghchi, on Thursday, condemning Iran’s strikes on ships in the strait.

“His Excellency stressed that such actions would undermine trust, threaten international maritime security, and harm efforts to consolidate regional security and stability,” a statement from the Qatari foreign ministry said.

Negotiations towards reaching a final deal were intended to start after Thursday’s funeral of Khamenei. The two days of strikes meant that talks would be held amid escalating tensions

Trump had said on Wednesday that negotiators were “wasting their time”. Iran’s deputy foreign minister, Kazem Gharibabadi, shot back at Trump, calling his comments “a confession to the failure of a policy that has been based on force, sanctions and threats for years and could not bring the Iranian nation to its knees”.

Gharibabadi wrote on X: “With the criminal and the murderer Trump, one must speak his own language, apparently understands the language of force better!”
