Pyongyang said to be planning to increase support despite high casualties among estimated 11,000 already sent

North Korea is preparing to send more soldiers to fight in the Ukraine war, military officials in South Korea have said, despite reports of heavy casualties among troops from the communist state who have already been sent to the battlefield.

The claim that Pyongyang could be planning to increase its support for the Kremlin came as Donald Trump suggested he would attempt to rekindle his relationship with Kim Jong-un, describing the North Korean leader as a “smart guy” in an interview with Fox News.
