Putin warns of 'global catastrophe' over N Korea

Vladimir Putin said the North Korean crisis could cause a "planetary catastrophe". He said many people would die. He said talking was the only answer. Mr Putin warned that military action was very dangerous. He said North Korea would "eat grass" instead of stop its nuclear programme because they do not feel safe.

Tensions are dangerous because North Korea carried out its biggest ever nuclear test. The UN told North Korea to stop. Mr Putin said sanctions against North Korea will never work. The USA said North Korea was "begging for war". It said: "War is never something the US wants….We will defend our allies."
