North Korean leader Kim Jong-un oversaw a joint strike drill by his military, expressing his firm conviction that the North's armed forces will steadily develop its combat capability, state media said Friday.

Kim attended the drill Friday, "to judge the mobility and the fire power strike ability of the defense units on the front and in the eastern area," according to the Korean Central News Agency.

Kim expressed "his admiration for the combat capability of the units of the services of the KPA, and for defense units on the border and eastern areas keeping themselves fully ready to go into action on a moment's notice," KCNA said.
