Cohabitation is difficult on the front line. Putin's armed forces avoid all contact with them, considering them “cruel and devoid of humanity.” Testimonies from Russian prisoners speak of many problems with North Koreans on the front line.

Weapons and notes left on dead North Korean troops in Russia give Ukraine a glimpse into their mindset — and show how they are quickly adapting to modern war.

Ukrainian President Volodymyr Zelenskyy posted a video showing the apparent interrogation of two North Korean soldiers captured alive in the war.

Ukrainian soldiers, along with units of the Ukrainian Defence Forces, thwarted several Russian assault operations near Kursk. A recording of the intense battles was published online. Russian troops continue their attempts to push the Ukrainian Defence Forces' units out of the Kursk region in Russia.

Videos of captured North Korean troops posted online by Ukrainian President Zelensky show them admitting that they thought they were being sent on an exercise.

North Korean leader Kim Jong-un reportedly sent New Year’s messages to North Korean soldiers deployed in Russia's war against Ukraine, urging them to "fight with courage" until the end, according to a news report.

According to Ukrainian President Volodymyr Zelensky, North Korean soldiers were transported to Russian territory by ferry, then by train, and kept in total isolation as far as information was concerned.

Ukrainian operatives from special units have captured another group of North Korean soldiers in the Kursk region. Their equipment is surprising, as one was found carrying a modern Russian AK-12 rifle.
