Missile and drone strikes hit the Gulf within hours of a ceasefire announcement between Washington and Tehran, with Iran reporting that its Lavan Island refinery had been attacked and Kuwait, the United Arab Emirates and Bahrain later saying they too had come under fire, underscoring how quickly the truce was overtaken by events. Iranian state television said firefighters were battling a blaze at the Lavan site on Wednesday and that no casualties had been reported.
The strike on Lavan Island added a sharp new twist to a conflict that had already spilled well beyond Iran’s borders. The National Iranian Oil Refining and Distribution Company confirmed the refinery had been targeted in what it called an “enemy attack” at about 10 a. m. local time. Israel denied involvement, leaving the immediate responsibility unclear as smoke rose from one of Iran’s key energy assets in the Gulf.
What followed pointed to a broader regional chain reaction. Reuters reported that Iran struck oil facilities in neighbouring Gulf states, including a pipeline in Saudi Arabia used to bypass the Strait of Hormuz, while Kuwait, Bahrain and the UAE reported missile and drone attacks. Separate reporting from Kuwait said air defences were intercepting a morning wave of Iranian drones aimed at oil sites, power stations and desalination plants, signalling that critical civilian infrastructure had again become a battlefield.
For Gulf capitals, the episode reinforced the central fear that even a limited pause in direct US-Iran fighting does not insulate the wider region from retaliation, miscalculation or proxy escalation. The UAE and Saudi Arabia have spent years hardening air defences, yet the war has exposed the financial and strategic burden of repelling low-cost drone swarms with expensive interceptor missiles. Reuters reported this week that Gulf states, including Saudi Arabia and the UAE, are exploring cheaper interceptor drones as Iranian attacks drain stocks of US-made missiles.
The ceasefire itself was always fragile. European leaders welcomed the two-week pause announced on April 8 and urged all sides to turn it into a durable agreement. But the understanding appeared to rest on sharply different interpretations. Tehran said peace talks were unreasonable while Israeli strikes continued in Lebanon, whereas Washington maintained it had halted attacks on Iran and expected diplomacy to proceed. That gap in expectations meant the truce was vulnerable from the outset, especially once violence resumed on several fronts.
Energy markets, which had initially taken comfort from the ceasefire announcement, were forced to confront the deeper problem: the conflict is no longer only about military positions or nuclear diplomacy, but about the security of the Gulf’s industrial backbone. Lavan Island matters because it sits close to the shipping lanes and energy infrastructure that shape global oil flows. Any fire at a refinery there feeds concerns about supply disruption, insurance costs and the willingness of shipowners to return fully to the Strait of Hormuz, where traffic has remained constrained and operators have sought more clarity before resuming normal transit.
The wider chronology is equally important. Reuters says the war began on February 28 when President Donald Trump and Prime Minister Benjamin Netanyahu launched operations they said were aimed at curbing Iran’s regional reach and nuclear ambitions. More than five weeks later, the conflict has shown that Iran still retains the ability to strike across the Gulf with missiles and drones even after heavy blows to its military infrastructure. That reality helps explain why a refinery fire on Iranian territory and attacks on Gulf neighbours could occur on the same day as a supposed de-escalation.
For Kuwait and the UAE, the latest attacks carry both immediate and political costs. Kuwait has already faced direct spillover from the war, including an Iranian strike earlier this week on Bubiyan Island, where Tehran said US forces had relocated. The UAE, meanwhile, has been among the most exposed Gulf states during the conflict, according to broader reporting on repeated missile and drone threats. Those pressures are likely to deepen calls for stronger layered air defence, tighter coordination among Gulf monarchies and clearer guarantees from Washington at a moment when confidence in the old security architecture is under visible strain.
