US envoy Bill Richardson warns of Korea tinderbox
An unofficial US envoy visiting North Korea has warned that the situation on the peninsula is a "tinderbox".
Bill Richardson, made the comments after talks with officials in Pyongyang, whom he asked to exercise "extreme restraint".
He said he had urged them to let South Korea go ahead with planned live-firing exercises on an island which was shelled by the North last month.
Pyongyang has been threatening to strike back if the drill goes ahead.
