Tasnim gave no details on how the Iranian authorities had warned the unmanned drone to leave its airspace.
A U.S. defence official said last week that four of Iran’s Islamic Revolutionary Guard Corps (IRGC) vessels “harassed” a U.S. warship on Tuesday near the Strait of Hormuz.
Tehran said the ships had only been carrying out their regular duties monitoring foreign ships near Iranian waters.
