Tension is rising between the two Koreas as North Korean defector and conservative groups plan to send anti-Pyongyang leaflets to the North.
 
President of Fighters for Free North Korea Park Sang-hak said Monday that the group plans to send 500-thousand leaflets and 10-thousand copies of the film "The Interview" around March 26, which marks the fifth anniversary of the sinking of the South Korean warship, the Cheonan.
 
Park said his group hasn't received a request from the government to restrain from the campaign, and that it will move forward even if it does.
 
North Korea's main propaganda Web site, Uriminzokkiri, said sending leaflets across the border during war exercises is an open declaration of war.
 
The Rodong Sinmun, the newspaper of the North's ruling Workers' Party, said the South Korean government overlooking the leaflet campaign while cracking down on leaflets against President Park Geun-hye is a contradiction.
 
A Ministry of Unification official said there's no change in the government's position that the leaflet campaign is a matter of freedom of expression. Nevertheless, the official said that the government is looking into ways to ask civic groups to refrain.
