Russian have no troops close - they are all tied up in Izyum. Take away there, and another salient forms into Russian lines - they can’t win it seems.
“Russians have no troops close - they are all tied up in Izyum.”
Units had been re-deploying from that area to the Kherson front for the last several weeks - now they are cut off down there.

A lot of stuff is blowing up and burning behind Russian lines in Zaporizhzhia as well.
