Explosions in Novofedorovka. What was it?

The nature of the explosions in the video resembles an undermining from the inside, and not the result of a missile attack, but sabotage by the Ukrainian special services cannot be ruled out.

Explosions thunder on the Crimean coast, there are victims

Eyewitnesses report that explosions are heard from the Russian military air base in the village of Novofedorovka, which is near the resort town of Saki, and smoke is seen even on the beach in Evpatoria.
