Anchor: North Korea has been found to be exemplifying a double standard in its denouncement of the anti-Pyongyang leaflets sent across the border by South Korean civic groups. While the North has lashed out against such activities, even using them as a pretext to suspend inter-Korean dialogue, it has been revealed that North Korean leader Kim Jong-un has been working toward upping the ante in the North's own propaganda campaign.  
Our Park Jong-hong has this report.
 
Report: In the past, North Korea played up the superiority of its regime in propaganda leaflets sent to South Korea. Recent leaflets, however, now exude hostility, showing the North has taken a rogue turn in the past three years. 
 
Sending leaflets to the five islands in the West Sea, the North has used a menacing tone, making threats that it could turn Baengnyeong Island into an island of white bones if it opened fire.
 
A North Korean military document exclusively obtained by KBS has confirmed that the North’s leader Kim Jong-un is behind the leaflet threats.
 
The document dated on August 27, 2012 said Kim Jong-un visited a corps headquarters in the country’s eastern frontlines where he instructed the troops to make the leaflets look like an advertisement as a way to deal a psychological blow to the enemy. He also instructed the entire military to hold a leaflet contest.
 
Experts on North Korea believe the leaflets started to change following the North Korean leader's instructions.
 
Another military document from April of last year said the North also gave orders to step up monitoring the skies and searching the areas where leaflets from the South were suspected to have landed.
 
The North’s leaflet propaganda campaign was put on hold following the inter-Korean summit in 2000. But in the aftermath of Kim Jong-un’s rise to power, it has continued from 2012 until at least early this year.
