A South Korean activist has floated propaganda balloons including footage of protests in the Middle East toward North Korea, despite Pyongyang's threat to retaliate.
Park Sang-hak says the balloons were launched Thursday from a hill near the border. They also carried 1-dollar bills and 200,000 propaganda leaflets.
The move came days after North Korea's military warned it would fire at South Korean border towns if Seoul doesn't stop the leaflets.
South Korea says it cannot do that, citing freedom of speech protections.
Park says that he won't yield to what he calls North Korean blackmailing. He says he will dedicate himself to letting North Koreans know what's going on in the world.
