North Korean authorities have released this image purporting to show the country’s leader Kim Jong-un signing the order to conduct the test on a hydrogen nuclear device which it claimed was carried out today. North Korea stated that it successfully tested a ‘Hydrogen Bomb’ at its main nuclear test site today. State media announced the test after monitors detected a 5.1 magnitude quake close to the Punggye-ri site.
