Deadly Ukrainian attack on Iranian vessel 'cannot go unanswered,' Tehran says

Iran vowed revenge after a Ukrainian drone attack on an Iranian vessel killed an Iranian sailor.

Ukraine launched several long-range drones targeting ships in the Caspian Sea, hitting at least one Iranian commercial vessel. Zelensky confirmed the strike on Saturday, saying Ukraine had achieved “very strong results with long‑range strikes in the Caspian Sea – including vessels used in military cargo shipments involving Iran, as well as a warship.” Iran said the vessel hit was purely commercial and demanded that action be taken.
