I honestly have no idea what to believe in this. Could be any number of things.
Could be Russian partisans attacking civilians
Could be Ukranian soldiers attacking civilians
Could be Ukranian soldiers attacking civilians because they approached a checkpoint that was supposed to be closed to traffic
Could even be a negligent discharge, it kinda looks like the sound of a shot went off after the (passenger? passenger side is on the left?) was thrown against the back of the car.
