Tehran “will take the necessary action” against US forces, state news reported on Monday, after the US military captured an Iran-flagged ship along the choked Strait of Hormuz over the weekend.

The Iran Revolutionary Guard Corps (IRGC) had been “prepared to respond decisively to the invading American forces” following their “blatant aggression,” according to the IRGC-linked Tasnim News Agency.

However, Iranian forces “faced certain limitations” over the presence of family members of the ship’s crew on board, Tasnim added.

“Given the current circumstances, once the safety of the families and crew of the vessel targeted by the United States is ensured, the powerful armed forces of the Islamic Republic of Iran will take the necessary action against the terrorist US military,” the agency said.

US naval forces captured an Iranian cargo ship trying to cross through a US blockade on the Strait of Hormuz on Sunday, prompting Tehran to cast doubt on a second round of ceasefire talks scheduled this week and further souring tensions between the warring parties.
