Residents of occupied Kadiyivka (formerly Stakhanov) have confirmed to Radio Liberty's Donbas Realiyi project the explosions at the occupiers' depots last night.
The explosions happened around 3 a.m., after which the ammunition began to detonate, Radio Liberty said.
"It is still exploding. Heavy smoke, hard to breathe. The private sector is affected. In eight years this has never happened before," an eyewitness from Kadiyivka said on the condition of anonymity.
There have been no official reports on the destruction yet.
Kadiyivka has been occupied since 2014.
