We are talking about attacks on military airfields in the Saratov, Ryazan and Kursk regions. “These were Ukrainian drones – very successful, very effective,” the source said. He added that the Russians "sowed the seeds of anger and now they will reap the whirlwind."

At the same time, the official did not give any details of the attacks. Ukraine has not officially confirmed its involvement in attacks on airfields.
