The object was to reach the Village of Daechuri - which is scheduled for demolition in order to expand the U.S. military base Camp Humphreys. The rally was in support of the Korean famers who refuse to move from their homes in Daechuri. The government denied a permit for the peaceful demonstration and posted 10,000 police and soldiers around the village to prevent the marchers from reaching their destination. All roads to Daechuri were blocked so the marchers were forced to try to reach Daechuri by walking through the fields near the village. Here are my photos.
