Ukraine Strikes Iranian Vessel in the Caspian Sea; Tehran Warns of Retaliation

Ukraine struck an Iranian-flagged ship in the Caspian Sea, killing one sailor. Tehran called it a "criminal act" and warned of retaliation. Kyiv says the vessel ferried military cargo between Iran and Russia. The strike reaches a corridor where Iran maintains naval presence, raising the risk that two separate conflicts — the Ukraine war and Iran's regional standoff — could converge.
