North Korea's Kim vows a ‘beautiful life’ for families of soldiers killed fighting for Russia

North Korean leader Kim Jong-un has promised "a beautiful life" for the families of "martyrs" who perished fighting for Russia in the war against Ukraine, state media said, praising the bereaved for the heroism of their sons and husbands.

Kim, on Friday, hosted the families of soldiers and expressed "grief at having failed to save the precious lives" of the fallen men who sacrificed their lives to defend the country's honour, KCNA state news agency reported on Saturday.

The heroic feats of the soldiers and officers were possible because of the strength and courage given to them by families who are "the most tenacious, patriotic and just people in the world," Kim told the parents, wives and children, KCNA said.

"They did not write even a short letter to me, but I think they must have entrusted their families, including those beloved children, to me," Kim was quoted as saying.

The country will "provide you with a beautiful life in the country defended at the cost of the lives of the martyrs," he said.

The meeting was the latest honouring of troops who suffered heavy casualties in Russia's Kursk region that borders Ukraine, after Kim and Russian President Vladimir Putin acknowledged the deployment in April after months of silence.

At the ceremony last week, images released by KCNA showed an emotional Kim embracing a returned soldier who appeared overwhelmed, burying his face in the leader's chest.

The leader was also seen kneeling before a portrait of a fallen soldier to pay his respects and placing medals and flowers beside images of the dead.
