According to the released account, fighters of Ukraine’s 225th Separate Assault Regiment counterattacked and regained positions previously held by Russian forces. Shortly afterward, their position was targeted by an FPV drone and a munition reportedly carrying an unknown toxic substance. The soldiers managed to leave the dugout in time and move to another position.
The incident was documented, and the available evidence has reportedly been handed over to the relevant authorities for inclusion in investigations into alleged Russian war crimes.
