South Koreans were alert Friday for possible new launches by North Korea of balloons carrying rubbish into the South, a day after Seoul activists flew their own balloons to scatter political leaflets in the North.
Any resumption of trash balloon launches by North Korea would likely prompt South Korea to respond, possibly with anti-North Korean loudspeaker broadcasts or live-fire exercises along their heavily fortified border. North Korea would probably retaliate with its own measures, further escalating tensions between the rivals.
