"These were Ukrainian drones — very successful, very effective," the anonymous official told the newspaper, referring to all three attacks.
This is already the second unofficial confirmation of Ukraine's responsibility for the drone attacks, which took place on Monday and Tuesday. Another anonymous Ukrainian official told The New York Times that the drones were launched from the Ukrainian territory.
Reporting the attacks, the Russian Defense Ministry said Ukraine used Soviet-made combat drones. The Russian air defense intercepted the drones, but their fragments killed three and injured four Russian servicemen in Ryazan and Saratov on Monday. There were no casualties as a result of the attack in Kursk on Tuesday.
