N. Korea carries out "very important" test at satellite launch site-KCNA

North Korea has carried out a "very important" test at its Sohae satellite launch site, state media KCNA reported on Sunday, a rocket testing ground that U.S. officials once said North Korea had promised to close. Tensions have risen ahead of a year-end deadline set by North Korea, which has called on the United States to change its policy of insisting on Pyongyang's unilateral denuclearisation and demanded relief from punishing sanctions.
