 More garbage is falling from the sky in South Korea. Previous balloons sent south by North Korea carried waste paper, cigarette butts, even manure, more than 2,000 since late May. After a pause, this tactic appears to have resumed. South Korea's Joint Chiefs of Staff say the balloons are flying north of Seoul, just an hour's drive from the border. Citizens are warned to watch out for falling objects and report any grounded balloons to authorities.
