South Korea blocks leaflet launch after North 'strike' threat

South Korean police have blocked activists from sending propaganda leaflets over the border, after threats of military action from North Korea.

A group of North Korean defectors now living in the South had planned to launch balloons carrying the leaflets near the border town of Paju.

On Friday Pyongyang threatened to open fire on South Korean territory if the launch went ahead.

The BBC's Kevin Kim in Seoul said that tensions appeared to have eased after it became clear that the protest would not be allowed to go ahead.
