A U.S. Navy destroyer operating in the Arabian Sea enforced the ongoing naval blockade of Iranian ports on Sunday when it fired on a cargo vessel attempting to sail toward an Iranian port.
The Iranian-flagged M/V Touska was transiting the north Arabian Sea toward Bandar Abbas, Iran, when it was intercepted by the guided-missile destroyer USS Spruance and issued warnings that it was in violation of the blockade, U.S. Central Command announced on Sunday.
“After Touska’s crew failed to comply with repeated warnings over a six-hour period, Spruance directed the vessel to evacuate its engine room,” the CENTCOM release stated. “Spruance disabled Touska’s propulsion by firing several rounds from the destroyer’s 5-inch MK 45 Gun into Touska’s engine room.”
U.S. Central Command published a brief video of the encounter.
U.S. Marines assigned to the 31st Marine Expeditionary Unit subsequently boarded the vessel, the release stated. The Touska remains in U.S. custody.
Acknowledging the encounter in a post on Truth Social, U.S. President Donald Trump stated that “an Iranian-flagged cargo ship named TOUSKA, nearly 900 feet long and weighing almost as much as an aircraft carrier, tried to get past our Naval Blockade, and it did not go well for them.”
“The Iranian crew refused to listen, so our Navy ship stopped them right in their tracks by blowing a hole in the engineroom,” Trump added. “The TOUSKA is under U.S. Treasury Sanctions because of their prior history of illegal activity. We have full custody of the ship, and are seeing what’s on board!”
The U.S. Navy blockade, which involves 10,000 troops, over a dozen warships and more than 100 fighter and surveillance aircraft, went into effect on April 13 following failed peace talks between the U.S. and Iran.
Any vessels transiting to and from Iranian ports are subject to the blockade, CENTCOM officials stated, while ships not visiting Iranian ports can still navigate the Strait of Hormuz.
Iran, meanwhile, said it would retaliate for Sunday’s incident, as tensions continued to escalate Sunday amid a fragile ceasefire.
“We warn that the armed forces of the Islamic Republic of Iran will soon respond and retaliate against this armed piracy by the U.S. military,” an Iranian military spokesperson said, according to state media.
Iranian state media also reported that Tehran had rejected new peace talks, citing the ongoing blockade, threatening rhetoric and Washington’s shifting positions and “excessive demands.”
“One cannot restrict Iran’s oil exports while expecting free security for others. The choice is clear: either a free oil market for all, or the risk of significant costs for everyone,” Iran’s First Vice President Mohammadreza Aref wrote on social media.
U.S. forces have encountered and redirected 25 commercial vessels since launching the blockade, according to CENTCOM.
