This was reported by the Special Operations Forces.
The assault by North Korean soldiers lasted all day — from morning until night.
During this time, the SSO forces managed to eliminate 17 military personnel from the DPRK. In the morning, they encountered one of the surviving soldiers who had fought alongside the Russians. He attempted to deceive the Ukrainian soldiers by luring them in, intending to blow himself up along with them.
However, the SSO warriors quickly deciphered the North Korean's plan and moved away from him. He detonated, but there were no casualties among the Ukrainians.
On January 5, the Ukrainian Defense Forces attacked the Russians in several directions in the Kursk region of the Russian Federation, stated Andrey Kovalenko, head of the Center for Counteracting Disinformation under the National Security and Defense Council. According to him, this came as a surprise to the Russians.
Russian bloggers also reported on the Ukrainian military's offensive, which is ongoing northeast of Sudzhi toward Bolshoye Soldatskoye, as well as heavy fighting near the Berdin farmstead.
By January 7, the American Institute for the Study of War (ISW) noted in its report that the Ukrainian military had achieved tactical successes in the Kursk direction following the initiation of new offensive operations.
