'Dirty' depiction of Kim's wife outraged NKorea: Russian envoy

North Korea's fury over anti-Pyongyang leaflets launched from the South is driven by "dirty, insulting" depictions of leader Kim Jong Un's spouse, Russia's top envoy in the reclusive country has said. In recent weeks Pyongyang has issued a series of vitriolic condemnations over anti-North leaflets which defectors based in the South send across the militarised border -- usually attached to balloons or floated in bottles. The campaigns have long been a point of contention between the two Koreas, but this time, Pyongyang upped the pressure, blowing up a liaison office and threatening military measures.
