Despite the restoration of control over part of the border, the danger remains.
The enemy is constantly shelling the liberated border localities in the Sumy (north-east of Ukraine) and Chernihiv (north of Ukraine) regions. However, Ukraine managed to regain control of 1,200 km of the border. Two-thirds of this area is the border with Russia.
