SEOUL, Oct. 22 (Xinhua) -- South Korean authorities on Monday stopped activists from sending propaganda leaflets across the border following threats from the Democratic People's Republic of Korea (DPRK) to open fire.
Police and army blocked access to Imjingak, a pavilion at a tourist park just south of the heavily fortified border, where the activists, many of them DPRK defectors, had planned to launch giant balloons carrying anti-Pyongyang leaflets.
Police also ordered evacuation of some 820 residents along the demilitarized zone separating the two Koreas.
The military is put on high alert and has self-propelled howitzers and rocket launchers on standby, according to local reports.
Activists have regularly launched giant balloons loaded with propaganda leaflets which Pyongyang has denounced as "an undisguised psychological warfare."
