Photographs of leader with soldiers’ coffins were displayed at a gala concert marking anniversary of military treaty with Russia

Kim Jong-un has paid tribute to North Korean soldiers killed during Russia’s war with Ukraine, resting his hands on their repatriated coffins in a rare public acknowledgment that his armed forces have suffered fatalities in the conflict.

Photographs of the North Korean leader pausing in front of a line of half a dozen coffins draped in the country’s flag were displayed on a screen at a gala performance held on Sunday to mark the first anniversary of a military treaty between the North and Russia.
