Gavrilov also noted that Russian troops responded immediately to these actions, inflicting a massive strike on targets in Ukraine.
The diplomat added that this will happen every time if Kyiv continues acts of terrorism.
According to him, “no one should have any doubts” about this.
Earlier, the Pentagon reported that the United States did not coordinate Ukraine's strikes on Russian territory.
On December 5, the Russian Ministry of Defense reported that the Kyiv regime on the morning of December 5 attempted to disable Russian long-range aircraft and strike with Soviet-made jet drones at the military airfields of Diaghilevo in the Ryazan region and Engels in the Saratov region.
