N Korea conducted ‘successful’ hydrogen bomb test

North Korea had successfully carried out its first hydrogen bomb test marking a stunning step forward in its nuclear development. This was the country’s fourth nucleartest since 2006, but the first allegedly to involve a hydrogen weapon – also known as thermonuclear device.

• The regime in capital city Pyongyang detonated a hydrogen device at the Punggye-ri underground test site in the far northeast.
• UN Security Council prepares new sanctions as world leaders urge for “strong action” to be taken against Pyongyang following nuclear test which caused 1 magnitude earthquake.

Bombs which rely on nuclear fusion, release far more destructive power than other weapons based on a fission reaction.
