US and Iranian forces exchanged intense missile and drone attacks, with Iran targeting American facilities in several Gulf countries and again announcing the closure of the vital Strait of Hormuz, in a sharp escalation that casts a shadow over the future of the interim agreement the two countries signed last month.

US Central Command reported that its forces struck 140 Iranian military targets overnight, and more than 300 targets in raids spanning three nights this week, aiming to "undermine Iran's ability to attack civilian mariners and commercial vessels transiting the Strait."

In response, Iran's Islamic Revolutionary Guard Corps announced that it destroyed a command and control center and drone hangars at a base in Jordan, and targeted a US radar site and missile launch systems in Kuwait, as well as support and refueling platforms for a US aircraft carrier in Oman, and a fighter jet maintenance center and command facility in Qatar.

The Iranian strikes also reached Qatar, the mediator in ceasefire talks, which had not been attacked since last April. The Qatari government announced three injuries, including one child, from shrapnel during interception operations, holding Iran fully responsible. The UAE announced that its air defenses intercepted Iranian missiles and drones for the first time since early May, while Bahrain confirmed it intercepted several Iranian aerial attacks, and Jordan, Kuwait, and Oman reported similar attacks.

The Strait Management Authority in the Persian Gulf, recently established by Iran, announced that passage through the strait is currently impossible due to "illegal movements of US military forces in the region," indicating that permits will resume "as soon as stability and calm are restored." In response, US Central Command stated that "Iran does not control the strait and navigation continues," noting that the expanded southern route near Oman is available for navigation in both directions despite security threats.

Iran had announced late Saturday evening the closure of the strait after firing a warning shot that hit a ship taking an unauthorized route, and stopping a second ship on Sunday. India reported the loss of one of its citizens following an attack on the container ship "Galaxy" off the coast of Oman, while Oman rescued 23 of its crew members.

Official Iranian media reported explosions in the vicinity of Bandar Abbas port and Qeshm Island, with mention of the killing of an Iranian army officer.

US President Donald Trump said he considers the ceasefire to have ended, but he left the door open for further negotiations. The interim agreement the two countries signed last month aimed to reopen the strait and end the war through additional negotiations over 60 days.

It is worth noting that the war broke out following US and Israeli strikes on Iran on February 28, and that Iran's effective blockade of the strait contributed to rising global energy prices and escalating inflation, which is a politically sensitive issue for President Trump ahead of the congressional elections in November.

On the diplomatic front, talks were held in Oman between Iranian Foreign Minister Abbas Araghchi and his Omani counterpart Badr al-Busaidi, aiming to coordinate arrangements in the Strait of Hormuz, to be completed with Qatari participation. Araghchi also discussed developments in a phone call with Pakistani Foreign Minister Ishaq Dar, whose country plays a pivotal role in mediation between Washington and Tehran.

In this context, Iran's chief negotiator Mohammad Baqer Qalibaf wrote on platform X: "The era of unequal agreements is over, and we told you to keep your word or pay the price, and now reality is at the door."
