North Korea staged an apparent nuclear test of six to seven kilotons in a striking act of defiance that, if confirmed, is sure to trigger global condemnation from enemies and allies alike. Regional seismic monitoring agencies detected a seismic event, of a magnitude between 4.9 and 5.1, at 11:57 am (0257 GMT) with the epicentre in the same location as the North's Punggye-ri nuclear test site. —Photos and texts by Agencies
