• Russian officials visited Iran to check out drones, the Associated Press reported.
• The drones would be used in the war in Ukraine, the White House said, according to the AP.
• Last week, the national security adviser said he expected Iran to send weapons to Russia. 

Russian officials have visited Iran at least twice to see drones they want to use in Ukraine, according to the White House, the Associated Press reported. 

The AP reported that satellite images showed Russian officials visiting the Kashan Airfield in central Iran on June 8 and  July 5. 

The intelligence information comes as President Joe Biden visits the middle east and promised not to walk away from the region and "leave a vacuum to be filled by China, Russia or Iran."

A senior US official told reporters that the development shows that Russia is "effectively making a bet on Iran," the AP reported. 

Last week, National Security Adviser Jake Sullivan told reporters that Iran was preparing to provide Russia "with up to several hundred (unmanned aerial vehicles), including weapons-capable UAVs on an expedited timeline," CNN reported. 

"Our information further indicates that Iran is preparing to train Russian forces to use these UAVs, with initial training session slated in as soon as early July. It's unclear whether Iran has delivered any of these UAVs to Russia already," Sullivan added.
