The United States Central Command (CENTCOM) announced it had completed a ninth consecutive night of air and missile strikes against Iran early on Monday, targeting military command centres, air-defence and coastal-surveillance sites, naval assets, missile and drone launch facilities, and communications networks. The operation, which began at 7 p.m. Eastern Time on Sunday and concluded at 10 p.m., was described by CENTCOM as an effort to “further degrade” Iran’s capacity to attack commercial vessels and civilian mariners transiting the Strait of Hormuz. Iranian state-linked media reported explosions in at least eleven locations, including Tabriz, Mahshahr, Chabahar, Jask and Khormoj, while the semi-official Nournews agency, which is close to the Supreme National Security Council, listed the sites without detailing damage or casualties.

Viewed from Washington, the sustained campaign is a direct response to what the White House calls Iran’s violation of a memorandum of understanding that had committed Tehran to refrain from targeting merchant shipping in the strait. President Donald Trump told reporters the latest wave was “very hard” and conducted in honour of three US service members killed in recent days—two in a ballistic-missile and drone attack on a base in Jordan, and a third during a controlled detonation of unexploded ordnance from a downed Iranian drone in northern Iraq. The White House press secretary, Karoline Leavitt, said a full naval blockade of vessels bound for or departing Iranian ports was now in effect, and Trump asserted that the current operation was “much bigger” than previous efforts, aimed at ending Iran’s ability to project force rather than merely containing it. US officials, cited by the Washington Post, indicated the Pentagon is increasing the number of warplanes in the Middle East and planning for a wider war.

Tehran’s response, as articulated by the Islamic Revolutionary Guard Corps (IRGC), has been to launch fresh waves of ballistic missiles at what it termed “enemy targets.” The IRGC claimed to have struck US military aircraft at Aqaba airport in Jordan, as well as positions at Camp Udairi and Ali Al Salem airbase in Kuwait, and in Syria. It also asserted that two oil tankers had been disabled by explosions in the southern approach to the Strait of Hormuz after attempting to use a route the IRGC considers closed. Iranian state media reported the launch of missiles from Lorestan province without specifying targets or results. The IRGC issued a statement declaring US forces “legitimate targets” and called on Muslims to kill them, citing American operations in Islamic countries and support for Israel. None of the Iranian claims of extensive damage or casualties have been independently verified, and US officials have not confirmed the alleged strikes on Aqaba or Kuwait.

Regional capitals are now directly exposed to the fallout. Bahrain’s interior ministry sounded air-raid sirens and urged residents to seek shelter, while its defence force said it had intercepted and destroyed several Iranian aerial attacks. Kuwait’s military reported engaging hostile drones. The International Atomic Energy Agency (IAEA) said it was verifying reports of an overnight strike on the Darkhovin nuclear construction site in Iran, noting the facility was in very early construction stages and contained no nuclear material at the last inspection. The escalation follows the collapse of a temporary ceasefire earlier this month, which has reignited a full-scale struggle for control of the Strait of Hormuz—a chokepoint for roughly a fifth of global oil consumption—disrupting energy supplies and fuelling fears of global inflation.

The dossier remains in active combat phase. CENTCOM stated that its forces remain “focused, lethal and ready” and that the US military will continue to hold Iran accountable. Secretary of State Marco Rubio said Washington would keep striking as long as Iran attacks international shipping, while adding that the United States remains open to a diplomatic solution. No new talks have been announced, and the IAEA investigation into the Darkhovin site is ongoing. With both sides signalling further operations, the immediate trajectory points to an intensification of the nine-day-old conflict rather than a return to the brief truce that preceded it.
