That actually got me wondering what type of long range munitions an SU-34 can carry besides a Kinzhal.

Reading up a little, It’s highly likely that they are using improvised glide bombs, S8s and KH-29s, but those would be limited range munitions better used on the front lines.

However.

FAV-250’s have been used on civilians in the Belgorod region, where that plane was reported downed (from Russian sources). So yeah, those two were probably part of those civilian bombings.
