Ukrainian Prosecutor-General Yuriy Lutsenko has said that 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, UNIAN quoted RFE/RL as reporting.
Lutsenko told Inter TV that although he believes negligence by Ukrainian security forces guarding the depot in Kalynivka, Vinnytsya 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, Lutsenko told Inter.
"We have no proof that it was an unmanned aerial device in Kalynivka, but we have all the facts of a possibly planted detonator, which likely caused the explosion," he said. Lutsenko said Ukraine earlier this year detected a drone that investigators believe set off a massive explosion and fire on 23 March at a munitions depot on an army base in Balakliya, near Kharkiv.
The explosions and fire in both Kalynivka and Balakliya occurred late at night and thousands of people had to be evacuated from the surrounding areas.
