"As of 9 p.m. [Oct. 10], isolated explosions were taking place at two smoldering sites with a frequency of one or two blasts per hour. They no longer pose threat to the towns and villages located near the arms depot," the press service of the Ukrainian Defense Ministry said in a statement, Censor.NET reports citing Ukrinform.
According to Defense Ministry spokesman Colonel Oleksii Chernobai, units of the Ukrainian Armed Forces, together with the State Emergency Service, are taking measures to put out smoke and smoldering from the fire.
EOD teams are clearing the administrative territory as well as the territory near the arsenal from unexploded ordnance.
As reported, an explosion rocked the support area of the 6th arms depot near the town of Ichnia, the Chernihiv region, around 3:30 a.m. on Oct. 9 setting it on fire. The corresponding security measures were introduced all across the Chernihiv region.
The State Emergency Service reported at least 10,000 locals being evacuated from the danger zone.
The prosecutor's office opened criminal proceedings over negligence. The pre-trial investigation was entrusted to the Security Service of Ukraine (SBU) directorate in the Chernihiv region.
According to the SBU, there are three theories behind the causes of the accident, with the major one being an act of sabotage committed by a subversive group. Two others are the violation of the rules for fire safety or storage of ammunition, and deliberate arson or detonation in order to conceal the lack of ammunition.
