Russia is supplying Iran with Shahed drones to use against the U.S. ​and Israel, Ukrainian President Volodymyr ‌Zelenskiy told CNN in an interview excerpt aired on Saturday.

Zelenskiy told CNN’s Fareed ​Zakaria that it is “100% facts” ​that Iran has used Russian-made Shaheds ⁠to attack U.S. bases.

Iran pioneered the Shahed drone, ​a much cheaper alternative to expensive ​missiles. They first saw mass use in Russia’s ‌invasion ⁠of Ukraine, where thousands of them have been launched by Russian forces since fall 2022, according to the Ukrainians.
