The red and blue North Korean flag along with the Russian tricolor have reportedly been seen flying over Ukrainian territory. The Sun News is claiming that if the claim is true then North Korea is the first country to send troops.
So far other countries have provided assistance to Russia and Ukraine only by sending weapons and other goods.
At least 3,000 North Korean troops are present in the Kursk region of Russia and US officials fear they have been sent there to help Putin push back Ukrainian forces.
Ukrainian intelligence says Kim's troops are training at Russian military bases and fears they have been sent to join the war. The video, reportedly from Russia's Far East, shows Kim's soldiers undergoing military training with weapons.
Other footage shows North Korean soldiers posing for photos on Moscow's Red Square. Both Moscow and Pyongyang deny the presence of North Korean troops. South Korea's intelligence chief said North Korean troops are being trained in Ukraine to use equipment including drones. America and other western countries are also continuously making such allegations against Russia and North Korea.
