DUBAI (AP) — U.S. Marines boarded and seized an Iranian-flagged commercial vessel in the Arabian Sea early Sunday after the ship failed to comply with repeated warnings from American naval forces.

The incident occurred at approximately 4:30 a.m. local time on April 20, 2026, involving the M/V Touska. The vessel was intercepted by a U.S. Central Command task force that included the amphibious assault ship USS Tripoli and the guided-missile destroyer USS Spruance. U.S. officials stated the boarding was authorized after the ship ignored multiple hails and warnings to stop.

The M/V Touska, a commercial cargo ship flying the flag of Iran, was operating in international waters when it was approached by the U.S. warships. U.S. Central Command confirmed that the vessel did not respond to radio communications or visual signals, prompting the deployment of a boarding party from the USS Tripoli. The Marines secured the vessel without reported resistance or injury.

Iran has not yet issued an official statement regarding the seizure. The vessel's current location and the status of its crew remain undisclosed. U.S. officials indicated the ship is being held for further inspection and investigation. No details have been released regarding the cargo or the specific nature of the investigation.

The Arabian Sea has seen heightened naval activity in recent months, with U.S. forces conducting regular patrols to monitor maritime traffic and enforce international sanctions. This incident marks the latest in a series of maritime encounters involving Iranian-flagged vessels in the region.

The seizure raises questions about the vessel's intended destination and the nature of its cargo. U.S. officials have not specified whether the ship was suspected of transporting prohibited goods or violating sanctions. The crew's nationality and the ship's ownership have not been disclosed.

U.S. Central Command stated that the operation was conducted in accordance with international law and standard naval procedures. The command emphasized that the boarding was a defensive measure taken after the vessel failed to comply with lawful orders.

The incident is expected to draw diplomatic attention, with potential implications for U.S.-Iran relations. Regional observers are monitoring the situation closely, as similar incidents have previously led to heightened tensions in the Persian Gulf and Arabian Sea.

As of Sunday afternoon, the M/V Touska remained under U.S. control. No timeline has been provided for the release of the vessel or its crew. Further developments are expected as the investigation proceeds.
