Gerashchenko also said that militants are crossing the border of the Russian Federation carrying weapons, and Russian border guards are not taking any actions to arrest them.
"Russian FSB does not detain them in the territory of the Russian Federation, when they come to the border of Russia. What do you call this? I do believe that Russia is sponsoring terrorism. We must call things what they are," said Gerashchenko .
He noted that Ukraine is strengthening its borders.
"For twenty-three years we lived considering Russia a fraternal country. We did not expect that it will provides hordes of terrorists who are going to sow blood and hatred in our country. Therefore, we are strengthening the border. I think in the next few weeks these situations will not arise again. Besides, I can say that the groups of vehicles that are being prepared now will be destroyed from the air when they cross the Ukrainian border," said Gerashchenko .
