Russians suffer colossal losses in Kherson region - Kostenko, Ukrainian Security Service colonel

He told it "Espreso.TV" live on air.

"If Russians understood at least a little bit that they are simply destroying their resources on the right bank of Dnipro river, they would simply withdraw their troops. However, on the contrary, they keep their troops in Kherson and the Armed Forces of Ukraine successfully liquidate them. The Russians on this bridgehead suffer colossal losses. These losses are much greater for Ukrainians. And this despite the fact that we are attacking, and they are defending" - Kostenko said.

Ukrainian Security Service colonel emphasized that Ukraine should seriously prepare for the consequences of mobilization in Russian Federation.

"I think that Russians are betting on mobilization. They hope for the arrival of fresh forces. I want to note that mobilization is not only infantry, but also new calculations of tanks and artillery. We need to prepare for different scenarios. I am not saying that it will be possible for them to keep the occupied territories, but we should prepare for tough battles" - he added.
