North Korea Conducts 'Crucial Test' as Deadline Nears William Gallo SEOUL - North Korea said Saturday it had conducted a "crucial test" at a satellite launch facility to bolster its "reliable strategic nuclear deterrent." The test comes just weeks ahead of the country's self-imposed end-of-year deadline for the U.S. to provide more concessions in nuclear negotiations and amid its threats to resume long-range missile or nuclear tests. The Korean Central News Agency did not say what was tested Saturday and did not include pictures. However, it said the test occurred at the Sohae Satellite Launching Ground, where North Korea a week before said it conducted another "very important test," apparently of a rocket engine. North Korea has launched 13 rounds of short- or medium-range missiles since June. Some analysts predict it may soon use the Sohae site to launch a satellite into space using long-range missile technology.
