Iranian authorities have increased attacks on commercial ships transiting the Strait of Hormuz since the funeral of supreme leader Ayatollah Ali Khamenei, according to reports. The United States responded by striking more than 170 sites in Iran, including military facilities and infrastructure such as a bridge in the north and a rail line linking Tehran to Mashhad, as stated by U.S. officials. The Strait of Hormuz was declared closed to maritime traffic by the Islamic Revolutionary Guard Corps, which said a commercial vessel was hit after entering an unapproved route. President Donald Trump posted on social media that the ceasefire was over and threatened to destroy Iranian areas, saying "1000 Missiles are Locked and Loaded and aimed at the Islamic Republic of Iran." Senior U.S. officials said Iran described the attacks as actions by a rogue unit of the IRGC and expected Iran to issue a statement within days confirming the strait would be open and that attacks would cease. Back‑channel talks mediated by Qatar were said to be aimed at a broader peace agreement. Iranian officials, including interim prayer leader Mohammad Hassan Abutorabifard, said the attacks were intended to demonstrate strength and that the era of aggressive deterrence had begun. Analyst Behnam Ben Taleblu of the Foundation for the Defense of Democracies noted that hard‑line elements within Iran view escalation as linked to their survival. Public opinion in Tehran varied; some residents expressed support for the tough stance, while others voiced concern about renewed conflict and its economic impact, which includes an estimated reconstruction cost of $270 billion nationwide and damage to over 44,000 residential units in Tehran. The initial U.S.–Iran agreement, which included economic incentives, has been partially rolled back, with the United States rescinding a waiver on oil sanctions and imposing new financial sector sanctions. The situation remains unresolved, with both sides indicating willingness to negotiate but also signaling readiness for further escalation.
