He expressed his opinion on the air of the "Verdict with Serhiy Rudenko" program on the Espreso TV channel.
"I have always said that the battle for Kharkiv is still ahead. Since this is an important city for the Russians in terms of history and within the framework of, as they claim, the liberation of Donbas. Therefore, just as the battle for the South Ukraine is still ahead, we are also waiting for Kharkiv ", Kostenko is convinced.
The SBU colonel believes that the Russians can start an offensive again from several directions, but one will be the main one.
"It is definitely possible to simulate an attack from several directions. However, somewhere will be the main one. All others will be in order to tie down the forces and means of Ukrainian Armed Forces. This will make it impossible for the Ukrainian troops to maneuver for the main direction," he added.
