Something weird happened in east Ukraine today. Allegedly some insurgents from the "Gorlovka" group attacked a Ukrainian military checkpoint near the town Volnovakha in Donetsk oblast. Some 13 soldiers were killed, over 30 wounded and several armored personal carriers were destroyed (vid). There are no reports yet of wounded or killed insurgents.
It does not sound plausible to me that a group of rag tag insurgents only recently formed and without much fighting experience attacks a platoon plus size military unit and destroys it completely.
There is also video that shows two Ukrainian MI24-Hind helicopter gunships making several heavy bomb runs in the area of the incident. The Guardian's Shaun Walker confirmed that Ukrainian helicopters were involved. One explosion in the video seems to be followed by heavy secondary ones which is typically the case when an armed vehicle with lots of ammunition on board gets hit.
Did those helicopter pilots hit the Ukrainian military unit? That would explain the high casualty rate and rather heavy damage.
Was the checkpoint attacked before the helicopters destroyed it? By whom?
