South Korea Stops Anti-North Leaflet Launch

South Korean police on Saturday stopped a planned launch of anti-Pyongyang leaflets following a threat of violent retaliation by the North.

A group of defectors from North Korea and U.S. human rights activists had said they would use gas-filled balloons to drop 200,000 leaflets critical of Pyongyang over the tense border.

But a contingent of plain-clothed policemen prevented the activists from unloading the pamphlets and other materials for the launch from a pickup truck at Imjingak, a tourist site near the border.

Hours earlier, the North's military warned it would fire upon the launch site, denouncing the activists as "human scum" and warning the launch site was "within the range of direct sighting strike".

A leading activist, Park Sang-Hak, was taken into custody briefly after he attempted to drive the vehicle through a police line to get to the planned launch site, some 300 meters (1,000 feet) away.

"I'm wondering what they're so afraid of. Why is it illegal? Why is it wrong in what we are doing?" Thor Halvorssen, president of the New York-based Human Rights Foundation (HRF), told journalists.

"If South Korea is going to do everything because of threats from North Korea, then South Korea is a hostage. South Korea is not a free country," he said.

Police stopped similar launches in April and May this year, citing protests from local residents living in the area.

Local residents oppose such action as the North has threatened to shell sites used to launch leaflets which often carry messages such as calls for an uprising against the communist regime.
