Kirby said that the American side saw media reports about the incident.
“But we do not have any detailed information that would allow us to present our vision of what happened,” RIA Novosti quotes him.
The Russian Defense Ministry said that the Kyiv regime on the morning of December 5 tried to disable Russian long-range aircraft and made attempts to strike with Soviet-made jet drones at the military airfields "Dyagilevo" in the Ryazan region and "Engels" in the Saratov region.
Earlier it was reported that an explosion occurred at an airfield in the Ryazan region due to a fuel truck on fire.
