However, he did not specify the number of armored vehicles, which the terrorists brought to Debaltseve.
According to him, the Ukrainian soldiers are reinforcing the line of defense of the city and try to forecast the development of the situation.
"We have enough power to stop this force," the speaker of the National Security Council assured.
