“Found these in the Zaporizhzhya direction. The enemy is throwing chocolates with an explosive mechanism. Do not open them under any circumstances. Our guy was lucky that it did not detonate, otherwise he could have ended up crippled. I know guys whose fingers were torn off like that.”
Far more likely this is being prepared by Russians as they retreat in Kursk and blamed on Ukraine just in case any Russian civilians get hit. We know for a fact that Russia booby traps civilian areas which is a war crime. There have been zero cases of Ukraine doing this. So if a booby trap exists it should be assumed Russian.
