In a significant military operation, US Marines seized the Iranian-flagged cargo ship M/V Touska in the Gulf of Oman after the crew failed to heed repeated warnings over a six-hour period. The USS Spruance, a guided missile destroyer, fired rounds into the ship's engine room to disable its propulsion, allowing Marines from the 31st Marine Expeditionary Unit to board the vessel. This incident marks the first major seizure of a ship since the US imposed a naval blockade on Iranian ports. The Touska, which had departed from Port Klang, Malaysia, is under US Treasury sanctions due to its alleged involvement in illegal activities. US President Donald Trump confirmed the operation, stating that the US now has full custody of the ship and is investigating its contents. In response, Iran's military headquarters condemned the action, accusing the US of maritime piracy and threatening retaliation as a ceasefire window between the two nations approaches its conclusion on April 22.
