N. Korea carries out apparent nuclear test
SEOUL (AFP) - North Korea appeared to have carried out a threatened nuclear test Tuesday, with international monitoring agencies reporting a seismic event near the site of Pyongyang's nuclear test site.
The tremor, whose magnitude was estimated at between 4.9 and 5.1, was detected at 11:57am with the epicentre in Kilju county, where the North's Punggye-ri test site is located.
The US Geological Survey noted the seismic activity - also confirmed by monitors in South Korea, China and Japan - had a very shallow depth of just 1km.
The South Korean defence ministry and the presidential Blue House both said they were trying to verify whether a nuclear detonation had taken place.
