Ban Ki-moon warns North Korea crisis could be 'uncontrollable'

UN Secretary-General Ban Ki-moon has warned the crisis on the Korean peninsula may become "uncontrollable".

He once again urged North Korea to tone down its "provocative rhetoric" and to keep open a joint North-South Korean industrial complex.

Mr Ban said: "If any small incident is caused by miscalculation or misjudgement, it may create an uncontrollable situation.''
