A Ukrainian military drone unit near Stepove, a village just north of Avdiivka, where some of the most intense battles have taken place, shot the video this month.

It’s an apocalyptic scene: In two separate clips, the bodies of about 150 soldiers — most wearing Russian uniforms — lie scattered along tree lines where they sought cover. The village itself has been reduced to rubble. Rows of trees that used to separate farm fields are burned and disfigured. The fields are pocked by artillery shells and grenades dropped from drones. The drone unit said it’s possible that some of the dead were Ukrainians.

The footage was provided to the AP by Ukraine’s BUAR unit of the 110th Mechanized Brigade, involved in the fighting in the area. The unit said that the footage was shot on Dec. 6 over two separate treelines between Stepove and nearby railroad tracks and that many of the bodies had been left there for weeks.
