The White House says Russian officials have visited an airfield in central Iran at least twice in recent weeks "to view weapons-capable drones it is looking to acquire for use in its ongoing war in Ukraine," the AP reports.

The White House claims Iran showed drones to Russian officials at the Kashan airfield on June 8 and July 15. The U.S. administration also released satellite images of the Shahed-191 and Shahed-129 drones, which were demonstrated and were in flight at the airfield while the Russian delegation's transport plane was on the ground.

White House national security adviser Jake Sullivan said in a statement that the administration has “information that the Iranian government is preparing to provide Russia with several hundred UAVs.”

“We assess an official Russian delegation recently received a showcase of Iranian attack-capable UAVs. We are releasing these images captured in June showing Iranian UAVs that the Russian government delegation saw that day,” Sullivan added in a statement. “This suggests ongoing Russian interest in acquiring Iranian attack-capable UAVs.”

Sullivan said U.S. officials believe the June visit “was the first time a Russian delegation has visited this airfield for such a showcase.”
