Ukrainian Prosecutor General Yuriy Lutsenko said investigators are operating under a theory that saboteurs may have used a detonator to trigger a massive explosion and fire at a munitions depot in central Ukraine this week, according to RFE/RL.
Lutsenko told Inter TV that although he believes negligence by Ukrainian security forces guarding the depot in Kalynivka may have contributed to the incident there, "we are inclined to presume that all recent blasts are part of the Russian Federation's warfare," RFE/RL reports.
"We see all signs of sabotage... We detected an unmanned aerial vehicle's flight across the Russian-Ukrainian border in Balakliya to drop thermobaric charges, which caused the explosions near Balakliya. Therefore, this is an act of sabotage on the part of Russia, which is destroying our military capability," he told Inter TV.
Investigators do not believe, however, that a drone was involved in setting off the explosions in Kalynivka in the Vinnytsya region, Lutsenko told Inter.

Lutsenko said Ukraine earlier this year detected a drone that investigators believe set off a massive explosion and fire on March 23 at a munitions depot on an army base in Balakliya, near Kharkiv.
