China calls for a return to talks to ease tensions on peninsula

The risk of a flashpoint is running high on the Korean Peninsula after Pyongyang announced it would rebuild and restart its nuclear facilities, analysts said.

"What we must be cautious of is accidental events that might be misread, resulting in a firefight or even larger disasters," said Huang Youfu, a professor of Korean studies at Minzu University of China. But he said the chances are slim that Pyongyang will launch a planned attack against the US.
