Iran’s Islamic Revolutionary Guard Corps, or IRGC, warned that any country supporting the United States would be considered a legitimate target. The warning, reported on July 26, 2026, said this could include the United Kingdom and Persian Gulf states.

An IRGC spokesperson said Israel would receive a devastating response if it returned to conflict. The report did not provide details on potential operations, types of targets, or any immediate action against a specific country.

The warning followed Tehran’s summoning of Ukrainian diplomats after a bombing of an Iranian vessel in the Caspian Sea. At least one soldier was killed and another injured in the attack. The report said Iran blamed Ukraine for the deadly attack on the vessel.
