"Signs of pessimism" about the Russian response to Ukraine's cross-border invasion in Kursk have started to emerge on Russian state TV, according to footage posted on social media.
The invasion seemed to catch Vladimir Putin unprepared, with a major retaliation yet to materialise and Russian forces struggling to stop Ukrainian advances.
Some pro-Kremlin military bloggers and Russian commentators have claimed that Russian forces are pushing back Ukrainian troops - but in one clip posted by BBC journalist Francis Scarr, "signs of pessimism have emerged".
Filmmaker and state pundit Karen Shakhnazarov said: "We could lose if such blunders continue. And this isn't defeatism, it isn't scaremongering."
