Kim said the danger of an armed confrontation on the Korean peninsula is fast becoming a reality because of hostile maneuvers by the enemies including the United States, requiring the country to "sharpen the sword" to protect itself.

"If they choose military confrontation and set the fire, we must mobilize all the most powerful means ... to deal a crushing blow and completely destroy them," KCNA state news agency quoted Kim as saying.

Kim hosted senior military leaders on Sunday at the ruling Workers' Party headquarters to congratulate them on the accomplishments made in 2023, KCNA said.

In separate reports, KCNA said Kim hosted a reception for senior members of the ruling party and attended a late night concert celebrating the new year.
