The White House said it believes Iran is planning to supply Russia with "several hundred" unmanned aerial vehicles (UAVs) amid its war Ukraine.
White House National Security Advisor Jake Sullivan said Monday, "Our information indicates that the Iranian government is preparing to provide Russia with up to several hundred UAVs, including weapons-capable UAVs on an expedited timeline."
Sullivan said it is unclear whether Iran has already sent some of its drones to Russia and said Washington officials have intelligence leading them to believe that Tehran is preparing to train Russian forces on the UAVs this month.
The security advisor said the fact that Russia was turning to other nations to help reinforce its brutal campaign in Ukraine shows that its war is "coming at a cost to the sustainment of its own weapons."
