The Russian president, Vladimir Putin, has warned that the escalating North Korean crisis could cause a "planetary catastrophe" and huge loss of life, and described US proposals for further sanctions on Pyongyang as "useless".
"Ramping up military hysteria in such conditions is senseless; it's a dead end," he told reporters in China. "It could lead to a global, planetary catastrophe and a huge loss of human life. There is no other way to solve the North Korean nuclear issue, save that of peaceful dialogue."
On Sunday, North Korea carried out its sixth and by far its most powerful nuclear test to date. The underground blast triggered a magnitude-6.3 earthquake and was more powerful than the bombs dropped by the US on Hiroshima and Nagasaki during the second world war.
Putin was attending the Brics summit, bringing together the leaders of Brazil, Russia, India, China and South Africa. Speaking on Tuesday, the final day of the summit in Xiamen, China, he said Russia condemned North Korea's provocations but said further sanctions would be useless and ineffective, describing the measures as a "road to nowhere".
