North Korean leader Kim Jong-un observed a special warfare unit's drill to destroy specific targets in South Korea, the North's Korean Central News Agency reported Sunday.

Kim watched the combat drill of the service personnel of the special operation battalion of KPA Unit 525, which included artillery shelling of and infiltration into key South Korean targets, such as the presidential office Cheong Wa Dae, the KCNA report said.

"Watching the brave service personnel independently and pro-actively perform their combat duty destroying specified targets of the enemy, he said with a broad smile on his face, 'Well done, the enemy troops will have no space to hide themselves, far from taking any counteraction,'" said the report dispatched in English.

Kim then praised the commanding officers and men for having bolstered up the unit, making it an unstoppable force, it added.

"He said that if the service personnel of the unit are to conduct bold combat actions with the southern part of Korea as their theater, they should stage intensive drills for marching, firing, swimming, overcoming natural obstacles and acquiring ability to maneuver in fields under the simulated conditions of an actual battle and thus firmly prepare themselves to be stalwart fighters for guerrilla warfare," the report said.
