The military did not specify the exact date of the battle but noted that Ukrainian infantry and snipers, equipped with small arms and grenade launchers, held off the North Korean army's advance on Ukrainian positions for over eight hours.

The 67th Separate Mechanized Brigade repelled an assault of Russian troops near the village of Zhuravka in Sumy Oblast on the border with Russia's Kursk Oblast, according to the brigade's Jan. 15 statement.

"Among them are officers, sergeants, and privates from motorized rifle units, Marines, airborne troops, and other units, coming from various Russian regions and the occupied city of Sevastopol," the Airborne Assault Troops' press service said.
