Kim Jong-un has passed a law allowing pre-emptive nuclear strikes in a move likely to raise tensions in the area.
The North Korean leader said it makes his country's nuclear status “irreversible” and claims it will stop any talk of denuclearisation.
Announcing the new law in front of the Supreme People’s Assembly, the dictator said: "The utmost significance of legislating nuclear weapons policy is to draw an irretrievable line so that there can be no bargaining over our nuclear weapons."
