Iran’s Revolutionary Guard Aerospace Force has warned of a “decisive, swift response” following what Tehran described as repeated US violations of a fragile ceasefire during ongoing diplomatic negotiations.
The warning came as tensions escalated around Iran’s southern Hormozgan province, where Iranian officials accused Washington of carrying out new military actions while peace efforts continued through regional mediators.
Seyed Majid Moosavi, commander of the Revolutionary Guard’s Aerospace Force, said the force remained “highly vigilant” and fully prepared for action, while criticizing ongoing negotiations with the United States.
In a post on X, Moosavi described “negotiation with the enemy” as “pure loss” and said forces were awaiting final orders from Iran’s commander-in-chief.
Iran’s Foreign Ministry also accused the US of conducting “aggressive acts” in Hormozgan, where Bandar Abbas and the Strait of Hormuz are located.
The US Central Command said it had targeted Iranian missile sites and boats allegedly attempting to place mines in southern Iran.
Centcom described the strikes as “self-defence strikes”.
Iran condemned the operations as a “gross violation” of the ceasefire and warned that the actions threatened diplomatic progress.
Iranian officials said the attacks demonstrated what they called a lack of American commitment to negotiations and accused Washington of undermining trust-building efforts.
The Islamic Revolutionary Guard Corps separately said it had shot down an American drone over Iranian territory.
Neither Tehran nor Washington has declared the ceasefire collapsed, but officials on both sides acknowledged that tensions were intensifying.
Diplomatic talks aimed at ending the conflict have continued through mediation led primarily by Pakistan, with additional negotiations taking place in Qatar.
US Secretary of State Marco Rubio said a deal remained possible but cautioned that negotiations would “take a few days”.
Discussions have reportedly focused on Iran’s frozen overseas funds, its stockpile of highly enriched uranium, and the Strait of Hormuz.
Iran has effectively blocked the waterway since the conflict involving the US and Israel began on 28 February, contributing to rising global energy prices.
Iran maintains its nuclear programme is for peaceful purposes, while the US, Israel, and Western allies accuse Tehran of pursuing nuclear weapons.
