On a mountaintop near the heavily fortified North Korean border, a group of human rights activists stuffs three large plastic bags with anti-Pyongyang leaflets, dollar bills and USB memory sticks loaded with popular South Korean soap operas and K-pop music.
They then strap the bags and a giant placard condemning North Korea’s ballistic missile launches to cylindrical 7m-tall helium balloons, which they release in the hope they will drift deep into the hermit kingdom.
It is the latest stunt by Fighters for Free North Korea, an activist group led by North Korean defector Park Sang-hak, who has for the past decade been at the vanguard of the propaganda campaign against the secretive Communist state.
