North Korea has floated another 600 trash-filled balloons across the border, the South's military said Sunday, with personnel in hazmat suits seen collecting piles of rubbish containing everything from cigarette butts to bits of cardboard and plastic.
South Korea has called the latest provocation from its nuclear-armed neighbour "irrational" and "low-class" but, unlike the spate of recent ballistic missile launches, the trash campaign does not violate UN sanctions on Kim Jong Un's isolated regime.
