On the 20th (local time), a spokesperson for Iran's Armed Forces Khatam al-Anbia Central Command announced that the United States violated the ceasefire agreement and fired at an Iranian merchant ship in the waters of the Gulf of Oman. According to the spokesperson, the US military committed acts of "maritime looting" by deploying numerous troops on deck and disabling the navigation system, and the Iranian military warned that it would soon retaliate against such piracy and armed robbery. Earlier on the same day, President Trump stated via social media that a US Navy missile destroyer intercepted and fired upon the Iranian cargo ship 'TOUSKA', which was attempting to break through a naval blockade in the Gulf of Oman, penetrating its engine room and bringing it to a halt, and that US Marines are currently in control of the vessel.
