SEOUL (REUTERS, AP) - North Korea said it had conducted another test at a satellite launch site on Friday (Dec 13) to bolster its strategic nuclear deterrence, North Korean state media outlet KCNA reported on Saturday.

KCNA on Sunday said that North Korea had carried out a "very important" test at the Sohae satellite launch site, a rocket-testing ground that US officials once said North Korea had promised to close.

The latest KCNA report called the event on Friday a "successful test of great significance" but did not specify what was tested.
