Iran Warns Ukraine After Drone Strike Kills Sailor on Iranian Ship

Iran's foreign minister warned Ukraine that a July 25 drone strike on an Iranian-flagged vessel in the Caspian Sea, which killed one sailor, "cannot go unanswered." Ukraine said it targeted ships carrying Iranian-linked military cargo and a Russian warship. Iran denies involvement in the Russia-Ukraine war. Tehran summoned Ukraine's envoy and briefed EU and Russian counterparts.
