Ukraine on Sunday launched one of its largest drone-based operations on Russia to date, striking five air bases deep inside Russian territory. Russia said several of its aircraft "caught fire" in the attacks. "As a result of the launch of FPV drones from territories in the close proximity to military airfields in the Murmansk and Irkutsk Regions, several aircraft caught fire. The fires were extinguished," the statement said. Ukraine, however, said at least 40 aircraft had been damaged specified that they included nuclear capable TU-95 and Tu-22 strategic bombers.
