The United States launched a fresh wave of strikes against Iran on Wednesday, targeting Iranian military capabilities in the Strait of Hormuz, as President Donald Trump warned Tehran it must better behave. In response, Iran carried out retaliatory strikes against what it described as US assets in Bahrain, Kuwait, and Jordan, triggering air raid sirens across the Gulf. Amid the escalating hostilities, Trump announced that Iran had released a US citizen, Dena Karari, who had been detained since December 2024 on what her lawyer called bogus charges.

US Strikes Escalate

The US military announced on Wednesday that it had carried out a second wave of strikes against Iran during daylight hours, further degrading Iran's ability to attack commercial shipping in the Strait of Hormuz. According to BBC News, a 90-minute wave earlier in the day targeted Iran's coastal defenses and cruise missile storage and launch sites on Greater Tunb Island. US Central Command (Centcom) stated that the strikes were aimed at Iranian military capabilities used to threaten vessels moving through the strategic waterway. Later, at 21:00 ET (01:00 GMT), Centcom reported a second wave of attacks, though details were not immediately disclosed.

President Trump, speaking at a defense summit, warned that Iran was not happy with the current situation and that the US would decide whether to settle with Tehran or finish it off. He told reporters that he did not like giving deadlines but that Iran knew the story and had better behave, as reported by BBC News. The escalation follows Trump's earlier threat to bomb bridges and power plants if Iran did not return to talks next week.

Iran Retaliates Against Gulf Nations

In response to the US strikes, Iran launched retaliatory attacks against what it described as US assets in the region. According to Al Jazeera, air raid sirens sounded in Bahrain and Kuwait as Iranian strikes hit targets in those countries, as well as in Jordan. Iranian media reported explosions on Qeshm Island, Bandar Abbas, and Chabahar, indicating that the US strikes continued to hit key cities in southern and western Iran. The Iranian army claimed to have carried out attacks on US targets, though the extent of damage was not immediately clear.

The strikes came even as Iran's Foreign Minister Araghchi visited Qatar to pay respects following the death of the Father Emir, Sheikh Hamad bin al Thani, according to Al Jazeera. The diplomatic visit underscored the complex dynamics of the conflict, with Iran engaging in both military action and diplomatic outreach.

Civilian Impact and Damage

Iranians have been inspecting the damage from days of US strikes on key cities in the country's south and west. According to Al Jazeera, residents reported that attacks had damaged ports and at least one hospital. An Iranian doctor stated that a US strike had damaged a children's cancer hospital, raising concerns about the humanitarian impact of the military campaign. The US military has not commented on the specific claim, but the incident adds to the growing toll of the conflict on civilians.

Release of US Citizen Dena Karari

Amid the military escalation, President Trump announced on Wednesday evening that Iran had released a US citizen who had been wrongfully detained since December 2024. In a post on Truth Social, Trump wrote that the woman was now safely outside of Iran and in good condition, and that the United States appreciated this gesture of goodwill by Iran, as reported by NBC News. The released citizen was later identified by her lawyer, Jared Genser, as Dena Karari, a dual US-Iranian citizen.

According to CBS News, Karari had been trapped in Iran since December 2024 on bogus charges of espionage and collaborating with a hostile state. She was never formally charged but was subjected to a coercive exit ban that prevented her from leaving. Her exit ban expired in April, but Iran did not allow her to exit at the time. She suffered a heart attack on July 8, according to two sources. Genser announced on social media that Karari was now safe and traveling back to the United States, crediting Trump's relentless efforts for her release.

The State Department declined to comment on the situation, but several other Americans remain imprisoned in Iran, including two who have been legally designated as wrongfully detained: Kamran Hekmati and Reza Valizadeh, as noted by CBS News.

Political and Diplomatic Context

The latest escalation marks a significant breakdown in the preliminary deal that had ended the earlier phase of the war. Iran's top negotiator, Mohammad Bagher Ghalibaf, told state media that Tehran had no reason to abide by the deal if it did not benefit from it, according to BBC News. He added that Iran's national security depended on maintaining Iranian arrangements in the Strait of Hormuz, and that negotiation, along with war, was part of Iran's strategy of resistance in what it described as an existential conflict with the US.

Trump's rhetoric has escalated in recent days. He threatened late on Tuesday to attack bridges and power plants if Iran did not return to talks next week. A previous threat in April to bomb Iran's civilian infrastructure drew condemnation from the UN human rights chief, who noted that deliberately attacking civilians and civilian infrastructure is a war crime under international law, as reported by BBC News. The Trump administration has also imposed a renewed blockade of Iran's ports, and the US military fired on a ship attempting to violate that blockade.
