Russian officials trained in Iran as part of drone deal, U.S. says

WASHINGTON (Reuters) -Russian officials trained in Iran in recent weeks as part of an agreement on the transfer of drones between the two countries, the U.S. State Department said on Thursday.

U.S. officials said last month that Washington had information that Iran was preparing to provide Russia with up to several hundred drones, including some that are weapons capable, and that Russian officials had visited Iran to view attack-capable unmanned aerial vehicles (UAVs).
