Hong Kong, Rabi'II 2, 1434, Feb 12, 2013, SPA - North Korea said Tuesday that it had conducted a new, more powerful underground nuclear test using more sophisticated technology, jolting the already fragile security situation in Northeast Asia and drawing condemnation from around the globe. It is the first nuclear test carried out under the North's young leader, Kim Jong Un, according to a report of CNN. The nuclear test Tuesday, which follows previous detonations by the North in 2006 and 2009, had greater explosive force and involved the use of a smaller, lighter device, the North's state-run Korean Central News Agency (KCNA) reported. --MORE 11:25 LOCAL TIME 08:25 GMT www.spa.gov.sa/1077650
