Iran Claims Seizure of US Underwater Drone; Tensions Rise in Hormuz Strait as Oil Prices Surge
September 28, 2026
The Iranian Revolutionary Guards claim they seized a second US unmanned underwater vehicle in the Gulf of Hormuz as part of an intelligence and electronic warfare operation, stating the device was on a reconnaissance mission in the Strait of Hormuz.
CENTCOM rejects the Iranian claim, with a spokesperson saying the United States maintains positive control of all drone assets in the region and that Iran does not hold the submarine or its data.
The IRGC Navy also declared the Strait of Hormuz closed and warned against unauthorized passage, reaffirming Iran’s sovereignty over the waterway.
Meanwhile, US President Trump suggested in interviews that oil prices would drop once Iran concedes and the war ends, implying the conflict could be resolved soon.
Iran warns neighboring countries about U.S. sanctions on its aviation sector, with several states restricting Iranian carriers and airspace, while Tehran signals possible coordinated responses if cooperation stays limited.
Reports indicate Trump rejected an Iranian seven-day halt in hostilities or open communication, arguing economic pressure and the naval blockade remain effective.
Oman urges restraint and dialogue, reiterating its mediator role and offering to continue safeguarding shipping through the Strait of Hormuz.
Colombia designates the IRGC as a terrorist organization and cuts ties with Iran, reflecting broader regional tensions linked to Hormuz and Tehran’s shifting alliances.
The broader Iran-U.S. confrontation includes a maritime standoff with the Strait of Hormuz under blockade and rising global oil prices, underscoring the strategic importance of the chokepoint.
Iran’s foreign minister Abbas Araghchi says Tehran has proposed a concrete seven-day plan to reopen the Strait of Hormuz, with the United States ultimately deciding whether conditions are met.
CENTCOM disputes Iran’s claimed total control of the Strait, citing ongoing cooperation with allies and challenging the assertion that the Iranian Navy remains operative.
State media describe the mission as espionage, with US forces depicted as hostile in Iranian broadcasts.
