U.S. says Iran is set to supply Russia with drones

U.S. says Iran is set to supply Russia with drones.

U.S. national security advisor Jake Sullivan said Iran is preparing to provide Russia with hundreds of unmanned aerial vehicles.

He said there are signs Iran is planning to train Russian forces to use these drones, which could begin as early as this month.

Sullivan said the information illustrates the kind of costs Russia has had to endure on the battlefield and how Moscow could turn to countries like Iran for support.

The U.S. will continue to work with Ukraine on a strategy that "achieves their objectives both on the battlefield and at the negotiating table," he said.

Sullivan made his comments ahead of President Joe Biden's trip to the Middle East, where he is expected to discuss a number of security issues, including a regional policy toward Iran. Relations with Iran have been strained as the two sides struggle for progress on a new nuclear deal.
