Iran in May 2026: the most important developments in security
In May 2026 security news from Iran was dominated by renewed US strikes during peace talks. On 26 May the US military struck missile launch sites and boats in southern Iran, calling the strikes self-defence; Iran said the US had violated the ceasefire and warned of a heavier response. The two sides traded strikes again on 27 May, and on 28 May the US hit a military site and a drone launch site, after which the Revolutionary Guards claimed a retaliatory strike on a US airbase in Kuwait. A report said the Kuwait attack injured five American personnel. On 31 May the Guards said they had downed a US drone, and the US fired Hellfire missiles at merchant ships bound for Iran to enforce its blockade. The Pentagon chief said the US was ready to resume strikes if no deal was reached.
The month began with clashes in the Strait of Hormuz. On 4 and 5 May the US and Iran exchanged fire as the US launched Project Freedom to guide ships out of the strait; President Trump said US forces shot down seven Iranian small boats. Iran fired missiles and drones at the UAE on several days. Trump paused the operation on 6 May, citing progress in talks, and after another exchange of fire on 8 May he called it a "love tap" and said the ceasefire held. The US kept up a naval blockade, deploying 61 ships by 10 May. Iran set up a transit system and a new authority for the strait and expanded the zone it claims; the Guards reported 26 to 35 ships a day passing under their coordination in the second half of the month.
The possibility of a wider war stayed open. Reports on 16 May said the US and Israel were preparing new strikes under the name Operation Sledgehammer; on 18 and 19 May Trump said he called off a planned strike at the request of Gulf states. US intelligence found that earlier strikes had not significantly damaged Iran's nuclear programme. Iran's supreme leader said enriched uranium must stay in the country, while Trump said the US would take it.
