South Korea raises its military alert level

North Korea may have carried out a threatened nuclear test as monitoring agencies report an "unusual seismic event".

An earthquake measuring 4.9 on the Richter scale was detected just north of a site where Pyongyang conducted nuclear tests in 2009.

The South Korean Defence Ministry, which raised its military alert level after the quake, said the suspected test had an explosive yield of between six and seven kilotonnes.

Spokesman Kim Min Seok said it had "enormous destructive power".

A UN nuclear test monitoring organisation detected what it called an "unusual seismic event" in North Korea.
