Iran’s Islamic Revolutionary Guard Corps (IRGC) has reportedly captured an oil tanker in a “special operation” in the Gulf of Oman, while the United States said it disabled two tankers attempting to enter Iranian ports.

The incidents came hours after the US and Iran exchanged fire in the Strait of Hormuz, threatening the fragile ceasefire and ongoing efforts to negotiate a lasting truce.

In a statement carried by Fars News Agency, an IRGC spokesperson said the Ocean Koi was seized for attempting to “disrupt oil exports and the interests of the Iranian nation.”

State-run Press TV released footage showing Iranian forces boarding the vessel, which is registered in Barbados, according to MarineTraffic.

Separately, US Central Command (CENTCOM) said American forces disabled two Iranian-flagged tankers trying to access ports in the Gulf of Oman.

CENTCOM commander Admiral Bradley Cooper said US troops remain “committed to full enforcement of the blockade of vessels entering or leaving Iran.”

Earlier Friday, both sides exchanged fire in the Strait of Hormuz.

US President Donald Trump said Iran had attacked three US Navy destroyers, while Iran’s top joint military command accused Washington of violating the truce by targeting an Iranian tanker and another ship, leaving 10 sailors wounded and five missing.

The Iranian command also claimed US air strikes hit civilian areas on Qeshm Island and said it retaliated by striking US vessels east of the strait and south of Chabahar port.

Trump later downplayed the exchange as a “love tap,” denying any breach of the current pause in fighting.
