Russia is preparing for an "extreme breakthrough" in the war against Ukraine, Secretary of the NSDC of Ukraine Oleksiy Danilov said in the telethon.

"They are preparing for an extreme breakthrough. The processes of changing people [in the military leadership] are related to this. They used Wagner fighters, Kadyrov fighters, the Russian army is being replaced," he said.

"They have a ‘last call.’ There will be no one else to change and write off the defeats they will suffer on our land," Danilov said.

According to him, "it may be on the anniversary [of the war], maybe in March.

"Their mobilization, which did not stop, is a challenge for us. We must prepare for their offensive attempt," the NSDC secretary said.
