Rumours are spreading that President Vladimir Putin, enraged by military setbacks in Ukraine, has launched a purge of some of Russia's most powerful officials.
On Thursday,
reports in Ukrainian media claimed that Putin had fired Roman Gavrilov, the deputy chief of Rosgvardia, the Russian national guard.
Rosgvardia had deployed into Ukraine alongside the regular military and suffered heavy losses as Ukraine resisted with unexpected ferocity.
Christo Grozev, the lead Russia investigator for the outlet Bellingcat,
said three sources confirmed the firing to him.
The Russian newspaper Kommersant meanwhile reported that Gavrilov had resigned.
One source told Bellingcat that Gavrilov was detained by the FSB's military counter-intelligence department over "leaks of military info that led to loss of life", while two others say it was "wasteful squandering of fuel."
The details of top-level moves in the Kremlin are difficult to confirm because of Russia's penchant for secrecy, the high costs of speaking out of turn, and the long campaign by Russia to destroy its independent media.
But even what can be seen suggests that all is not well in Putin's inner circle.
