"But we also know that other conflicts have started through an escalation caused by sleepwalking...We have to hope that the seriousness of this threat puts us on the path of reason before it is too late," he added.
He went on to stress that North Korea must halt is nuclear and ballistic missile tests and start adhering to United Nation Security Council resolutions.
"We must also maintain the unity of the Security Council at all costs, because it is the only tool which can carry out a diplomatic initiative with a chance of success," he added.
