Ukrainian Prime Minister Volodymyr Groysman has said that those responsible for the situation in Kalynivka in Vinnytsia region, where ammunition depots have been burning since Tuesday evening, must be held accountable.

"We need a clear-cut investigation and understanding of the cause of this emergency situation. This is the arsenal of our Ukrainian troops and I believe it isn't by accident that it is being destroyed now. But we need to make sure that all those who must be responsible for this are held accountable. I believe this is absolutely a matter of principle," Groysman said at a government meeting on Wednesday.

"I remember Mariupol, I remember Balaklia. And today this is Vinnytsia. Wise men draw conclusions. Fools repeat mistakes. I think the military cabinet presided over by the commander-in-chief, the country's president, is going to meet today to analyze the situation and make appropriate conclusions," Groysman added.

As reported earlier, Ukrainian President Petro Poroshenko has decided to convene a meeting of his military cabinet with the participation of Groysman, National Security and Defense Council Secretary Oleksandr Turchynov, and chiefs of law-enforcement and defense agencies over the ongoing explosions at ammo depots in Kalynivka. The officials will attend the meeting right after their return from Vinnytsia.
