North Korea has announced that it had conducted an underground nuclear test at its Punggye-ri Nuclear Test Site.
North Korean media claimed that it had successfully tested a hydrogen bomb, which was speculated to have existed the month before the test was carried out. The United States Geological Service reported a 5.1 magnitude earthquake from the location, the China Earthquake Networks Centre reported the magnitude as 4.9.
A newsreader on North Korean state TV said: “The republic’s first hydrogen bomb test has been successfully performed at 10:00 am on January 6, 2016.”
Last month, North Korean leader Kim Jong-un said the country had developed a hydrogen bomb, most however were sceptical.
North Korea declared in 2009 that it had developed a nuclear weapon, and the country reportedly possesses a small stockpile of relatively simple nuclear weapons, this is believed to have been the fourth test.
Since 2003, North Korea is no longer a party to the Nuclear Non-Proliferation Treaty.
