Iran plans to supply Russia with potentially hundreds of drones for its war in Ukraine, some with combat capabilities, a US official has said.
White House National Security Adviser Jake Sullivan said information the US had suggested Iran was preparing to train Russian forces to use the drones.
He added that it was unclear whether Iran had delivered them yet.
Iran said technological co-operation with Russia preceded the war, without confirming or denying the US claim.
Drones have played an integral part in the war for both Ukraine and Russia.
Just last week, Ukraine appealed for donations of thousands of drones to aid its war efforts.
Both sides are using them to spot the enemy’s positions and then help direct and correct their own artillery fire on a target.
