North Korea condemned South Korean civic groups for their plan to send anti-Pyongyang leaflets over the weekend by balloon, calling it a declaration of war. Seven conservative groups announced they would send 500,000 leaflets today from northern Gyeonggi near the border. The North issued another warning against insulting the dignity of its leadership with the leaflets. Earlier this month, North Korea fired at balloons carrying leaflets, with some shells landing in South Korea and prompting return fire.
