The Russian military is reinforcing its presence along the northern border as Ukrainian forces counter-attack around the city of Kharkiv, the Ukrainian military said Tuesday, APA reports citing CNN.
"Russia maintains certain forces and means of air defense in the Belgorod region [in Russia] in full readiness mode," the General Staff said, and "continues to focus its efforts on the defense of the occupied borders in order to prevent the advance of units of our troops toward the state border."
Kharkiv, Ukraine's second-largest city, lies about 24 miles (39 kilometers) from the border with the Russian region of Belgorod.
"It is expected that the Russian forces will continue defiant actions at the state border [with] Ukraine in order to restrain the actions of the Ukrainian armed forces," the General Staff said.
