"During the last week, the number of provocations on the Ukrainian-Russian border has significantly increased. The militants have regularly shelled the Russian territory by mortars and small arms, causing a death of a Russian citizen," Lysenko noted.
According to the speaker of the NSDC, the Russian side accuses the Ukrainian forces in shelling.
He noted that the Russian side has repeatedly violated the airspace of Ukraine, usually a few times a day the Russian militants and equipment attempt to break into the territory of Ukraine.
