The Korean People’s Army (KPA) vowed to initiate the strike if a group of North Korean defectors now living in the South went ahead with plans to scatter propaganda leaflets next Monday from balloons floated over the border.
The threat came a day after South Korean President Lee Myung-Bak made a surprise visit to an island close to the disputed maritime border that was shelled by Pyongyang two years ago.
“The moment a minor movement for the scattering is captured … a merciless military strike by the Western Front will be put into practice without warning,” the KPA said in a statement carried on the official Korean Central News Agency.
Residents in and around the area where the activists plan to launch their balloons should “evacuate in anticipation of possible damage”, the statement said.
