Uh, Ukraine (GUR) deliberately blew up a random civilian who was unwittingly transporting explosives for them across the Kerch Bridge. As well as whoever happened to be nearby (fortunately it was early morning so traffic was light). They also randomly shell residential areas in the Belgorod region and Donetsk city using low-accuracy tube artillery and Grad rockets (including cluster munitions and butterfly mines). The fact that Russia is guilty of much worse does not mean these are not war crimes.
