The North's leader said that the North's military should be ready to "ruthlessly" destroy Seoul's government bodies during his inspection of long-range artillery exercises, according to the Korean Central News Agency (KCNA), Yonhap News Agency wrote.
"All soldiers should be nurtured into warriors full of combat spirit and be on high alert," Kim was quoted as saying by the KCNA.
The report did not reveal when and where the drills took place.
The North's warning is the latest in a series of bellicose rhetoric in response to tougher U.N. sanctions on the North and ongoing joint military drills between Seoul and Washington.
The North said Wednesday that it is ready to turn President Park Geun-hye and her office into "a sea of flames and ashes," with its large-caliber multiple rocket launching system.
It said Thursday that it has successfully conducted a solid-fuel rocket engine test, boosting its ballistic rocket capabilities to hit its enemies.
