North Korean troops are suffering heavy losses in the fighting in Russia's Kursk region and facing logistical difficulties as a result of Ukrainian attacks, Ukraine’s military intelligence said Thursday.

Russia launched a massive attack on Ukraine’s energy grid, leaving many in the country in the dark over the holiday. Retired Col. Jack Jacobs shares his thoughts about recent developments in Ukraine and a potential twist in North Korea’s involvement.

The announcement followed reports from Ukrainian media outlet Militarnyi, which claimed the soldier was captured by Ukrainian special forces during operations in Russia’s Kursk region.
