A 2.9 magnitude earthquake has been recorded close to a nuclear testing site in North Korea, a US-based monitor has said, fuelling fears the country has tested another hydrogen bomb.

The earthquake is believed to have occurred around 23km north-east of Sungjibaegam – a known North Korean nuclear testing site. Although analysts cannot be 100% certain it is the result of a nuclear test, it shares many "characteristics" with past tests.

It comes after a 6.1-magnitude magnitude quake last month, which Kim Jong-Un claimed was the result of hydrogen bomb test.

A statement on the US Geological Survey website reads: "This event occurred in the area of the previous North Korean Nuclear tests... The event has earthquake like characteristics, however, we cannot conclusively confirm at this time the nature (natural or human-made) of the event."

This event occurred in the area of the previous North Korean Nuclear tests.

More to come.
