De-escalation Ukraine? Hardly?
First read from the "War is Boring" Internet web site.
Personally I hard time determining from the article if this school was located in Ukrainian controlled territory.
Here from the wiki Stanytsia Luhanska on the Ukrainian side of the frontline entrenchments:
"On 21 August 2014, Ukrainian forces reportedly were clearing Stanytsia Luhanska from the pro-Russian separatists. The settlement remained under control of the Ukrainian authorities. It became situated on the frontline with forces representing the Luhansk People's Republic and became regularly the victim of shelling. An early 2017 agreement between the Ukrainian army and the separatist forces of the war in Donbass on the disengagement of forces in Stanytsia Luhanska failed to materialise"
RATHER THAN A "FALSE FLAG" OPERATION I PERSONALLY WOULD CONSIDER THIS RATHER TO BE A PROVOCATION AND INTIMIDATION!
Additionally from the Twitter account of Anastasiia Laspatina:
"Russian shelling of Urainian territory today - across the entire frontline."
