"Meanwhile, panic appears to be setting in within Putin’s inner circle, with the Russian leader allegedly firing eight generals and putting the head of his FSB spy arm Sergei Beseda and his deputy under house arrest"

All that while 3 generals have already been killed in Ukraine in addition to uncounted number of officers with no major military success. That is bound to cause "friction" between various arms of the "siloviki". There is also a large fight brewing between FSB and Chechens (they have been in "cold war" state) as large convoy of Chechen forces in Ukraine was completely destroyed by Ukrainians based on information that seems to had been leaked by FSB.
