The Iranian military conducted drone strikes on US military vessels in the Gulf of Oman in retaliation for the seizure of an Iranian-flagged cargo ship, according to the semi-official Tasnim news agency.

In a social media post, the news agency said the strikes came after US President Donald Trump stated that the US navy had disabled and seized the Touska container ship on Sunday.

Meanwhile, Iranian Foreign Ministry spokesperson Esmaeil Baqaei condemned the US naval blockade of Iranian ports and coastline, describing it as unlawful and a violation of the Pakistani-mediated ceasefire.

In a post on X on Sunday, Baqaei said the blockade contravenes fundamental principles of international law and constitutes a crime against humanity.

“The United States’ so-called ‘blockade’ of Iran’s ports or coastline is not only a violation of the Pakistani-mediated ceasefire but also unlawful and criminal,” he said.

“It violates Article 2(4) of the UN Charter and constitutes an act of aggression under Article 3(c) of UN General Assembly Resolution 3314 (1974), which includes the blockade of a state’s ports or coasts among such acts.”

He added that the measures amounted to collective punishment of the Iranian population, which he said constitutes both a war crime and a crime against humanity.
