North Korea tests hydrogen nuclear device
North Korea has announced it successfully conducted a test of a miniaturised hydrogen nuclear device.
SEOUL - North Korea said it had successfully conducted a test of a miniaturised hydrogen nuclear device on Wednesday morning.
The announcement of a test being conducted followed a 5.1 magnitude earthquake near its known nuclear test site.
Just hours after North Korea carried out a hydrogen nuclear test, South Korea is warning it will take all necessary measures to protect its people.
The North's leader Kim Jong Un made public statements a few weeks ago confirming that the country was developing a hydrogen bomb.
The nuclear test is the fourth by the isolated country, which is under U.S. and UN sanctions for its nuclear and missile programmes.
The White House has released a statement in the last half hour saying it is aware of Pyongyang's claims of a nuclear test.
It says while it cannot confirm the claims just yet - it condemns any violation of the United Nations Security Council resolution.
