How Ukraine’s attack on Iranian ship in Caspian Sea blurred the lines between two wars

LONDON: With the attack by Ukraine on an Iranian ship in the Caspian Sea on Saturday, the boundaries between the world’s two largest ongoing wars are blurring, threatening to complicate already mired efforts to bring either to a peaceful conclusion.

Hours after the early morning attack, Ukrainian President Volodymyr Zelensky posted a message on X, celebrating his military having 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.”

The timing of the attack, in which Ukraine targeted and sank an Iranian cargo ship in transit to Russia, appears to have been no accident. Ukraine claimed the ship was carrying “military cargo,” almost certainly Iranian drones, swarms of which have been unleashed against Ukraine since Russia launched its full-scale invasion in 2022.

But although Ukraine has repeatedly attacked Russian ships in the Black Sea and Caspian Sea, this is thought to be the first time it has directly targeted an Iranian-flagged vessel.
