Russian missiles slammed into a Ukrainian military facility four miles from the village of Koty, Ukraine, on Sunday.
Thirty-five people died in the attack and 134 were injured, according to Yaroviv Gov. Maksym Kozytskyy.
At the training facility, formally known as the Yaroviv International Peacekeeping and Security Centre, soldiers and volunteers ran for cover amid the chaos as missiles battered the barracks.
One of the foreign volunteers stationed at the base told NTD reporter Dan Skorbach and Epoch Times reporter Ivan Pentchoukov of what happened.
