Reports Suggest Plan to Test Nuclear Bomb

Activity at a North Korean facility suggests Pyongyang could be preparing its first test of a nuclear bomb, according to news reports citing unnamed U.S. officials.

U.S. officials publicly gave no new evidence of any such plan.

ABC News quoted an unidentified senior military official as saying a U.S. intelligence agency had observed “suspicious vehicle movement” at a suspected North Korean test site.

CNN reported that U.S. military sources said satellite images showed wire bundles appearing at a suspected test site that could be used to monitor an underground test. It said the wires had not been connected to anything and it was unclear if a test was being prepared.
