Ukraine’s attack on an Iranian commercial vessel in the Caspian Sea marks the first direct link between the wars in Ukraine and Iran. The BBC reported Ukraine's ambassador to Israel, Yevgen Korniychuk, said the vessel had been carrying components for drones and missiles from Iran to Russia, not civilian cargo. Iranian officials reacted angrily to the attack, saying one sailor was killed and vowed retaliation. The Kremlin also weighed in, with spokesman Dmitry Peskov telling reporters that the Ukrainian attack should be seen as an attack on Iran itself. The BBC notes Iran started supplying Russia with its Shahed drones in 2022, when the war between Russian and Ukraine began.
