President Volodymyr Zelensky said Iran had effectively participated in Russia’s war against Ukraine from its earliest stages by supplying Moscow with drones, weapons and military technology, responding to Tehran’s threat of retaliation over a deadly Ukrainian strike on an Iranian vessel in the Caspian Sea. In an interview with Sky News, Zelensky was asked whether he was concerned about a potential Iranian response to the maritime attack.JOIN US ON TELEGRAMFollow our coverage of the war on the @Kyivpost_official. “What do you expect, if Iran transferred new technologies to Russia from the first year of the war?” Zelensky said, according to Suspilne. “These were Shahed drones. They transferred thousands of these drones in the first year of the war. Then they issued licenses. What did they do? Did they attack us? I think so.” His remarks followed a warning from Iranian Foreign Minister Abbas Araghchi that the Ukrainian attack “cannot go unanswered.” Iran said the strike caused an explosion aboard what it described as a commercial vessel, killing one sailor and injuring another. The Iranian Foreign Ministry condemned the operation as a “hostile and criminal” act and summoned Ukraine’s chargé d’affaires in Tehran to lodge a formal protest. Ukraine has presented a different account of the vessel’s role. Zelensky said that Ukrainian forces had struck vessels used to transport military cargo involving Iran in the Caspian Sea. The Security Service of Ukraine (SBU) also said one of the targeted vessels had been carrying military supplies between Iran and Russia.
