"The main deficiency of our military-political position is that, in a way, we are in full geopolitical isolation and that, however much we would hate to admit this, virtually the entire world is against us," he said. "And it's that situation we need to escape."

But Russia has continued to cover up or minimise its losses during a disastrous three-month campaign in Ukraine.

A month after the sinking of the Moskva, the Russian government has only confirmed the death of one crew member and said another 27 were missing. But the families of crew members say that the death toll could be as high as 200, and many have not received any confirmation about what happened to their husbands, brothers, and sons.

On Monday, the Ukrainian government also released new data claiming that Russia's 1st Guards Tank Army lost a staggering 131 tanks in just the first three weeks of the war, one of the bloodiest periods of combat for the Russian army.
