He shared the information on Espreso TV.
"The enemy does not stop trying to conduct sabotage activities, the most active area is the Sumy region. The largest number of attempts by enemy subversive reconnaissance groups is recorded there. The last group detected by the border guards and fired upon was also exposed in the Sumy region," noted Demchenko.
According to the State Border Guard Service of Ukraine spokesperson, a few days ago a Ukrainian group detected an attempt of a Russian subversive group to enter the country while patrolling.
"This Russian group tried to plant explosive devices in the path of our group. Our servicemen opened fire on the subversive group, and a small arms battle started. Artillery units joined in to hit the group. Anti-subversive reserves were also deployed to clear the area. Later, this Russian group moved beyond the state border. Such groups can be detected 1-2 times a week," added Demchenko.
On April 15, Ukrainian border guards prevented an attempt by a Russian sabotage and reconnaissance group to enter the Sumy region from Russian territory.
