Two senior Russian colonels have been caught insulting Vladimir Putin's flailing invasion of Ukraine and retreat from Kyiv in a secret recording, reports claim.
Russia has failed to make the significant headway expected since the invasion of its neighbour was launched on February 24 - and it has turned into a war of attrition.
Ukrainian soldiers have put up a fight over every inch of land, with the Russian army forced to change its strategy by withdrawing troops from the north and ditching attempts to topple the capital, instead focusing resources in more pro-Russian eastern regions close to the border.
