DPICM cluster munition midair deployment captured by a drone

Is the glow at the back of the round the "base bleed" in action?

Whose cluster bomb is this? Russia has been using them this whole time. It's my understanding the Ukrainians are more interested in taking the cluster bombs apart and using each bomblet as a done bomb. Using cluster bombs offensively means you have to advance through the unexploded ordinance you just dropped, since the dud rate is anywhere from 3-40% depending on who made the bomb.
