Anchor: North Korean leader Kim Jong-un has reportedly observed a special forces’ exercise simulating an attack on South Korean targets, including the presidential office. The North's state-run Korean Central Television(KCTV) on Sunday carried photos of Kim watching the drill of the special operation battalion.
Ro Aram has more.

Report: The North's KCTV showed Kim jong-un looking through a pair of binoculars to watch North Korean special agents descend from helicopters to attack a replica of the South Korean presidential office.

An artillery unit then opened fire at the mockup building. North Korean commandos infiltrated the building and reemerged dragging a dummy in civilian clothing.  

The young North Korean leader was seen bursting into laughter as he saw the drill that came in an apparent response to the South Korean military's plans for a decapitation mission with the U.S.

"[Leader Kim Jong-un] burst into laughter, saying 'good job, good job!, the enemy wouldn't even have time to hide not to mention fight back.'" 
 
The North's Korean People's Army Unit 525 was created by Kim. He threatened to turn the South Korean presidential office into a sea of fire, citing his military's deadly shelling of Yeonpyeong Island in November 2010.

The South Korean military denounced the North's commando exercise. Seoul's Joint Chiefs of Staff(JCS) said Sunday that if the enemy misjudges and commits a provocation against the South, the North Korean leadership will suffer a critical blow.
