U.S. Forces Disable Vessel Attempting to Enter Iranian Port, Violate Blockade

U.S. forces operating in the Arabian Sea enforced naval blockade measures against an Iranian-flagged cargo vessel attempting to sail toward an Iranian port yesterday.

The destroyer USS Spruance intercepted the M/V Touska as it transited the north Arabian Sea at 17 knots enroute to Bandar Abbas, Iran. American forces issued multiple warnings and informed the Iranian-flagged vessel it was in violation of the U.S. blockade. 

After the Touska's crew failed to comply with repeated warnings over a six-hour period, the Spruance directed the vessel to evacuate its engine room. The Spruance disabled the vessel's propulsion by firing several rounds from the destroyer's 5-inch MK 45 gun into the Touska's engine room.

Since the blockade's commencement, U.S. forces have directed 25 commercial vessels to turn around or return to an Iranian port.
