Vilkha MLRS
Neutral (?) reminder that my question was about what details your "Mossad" account on X was providing. You appear to have pivoted to the Russian MoD as a source, which to put it kindly, has not had the best record for truth and accuracy in this conflict.
If a Vikha was indeed used, the bomblet carriage should have survived and would be a very difficult to deny piece of evidence. I haven't seen anything yet to confirm one was recovered though.
Using cluster munitions on an essentially civilian target would be a serious change in tactics for Ukraine, and give Russia's allies in the US Congress a clear reason to drop support. That doesn't mean they couldn't have screwed up their targeting, or had a missile intercepted though, so I'd love to see any actual evidence.
