Washington, May 7, SPA -- The U.S. intelligence community is monitoring what appears to be preparations by North Korea to conduct a nuclear test, a Defense Department official told CNN Friday. But the official strongly emphasized that it is unclear whether the activity is real or deceptive. The official said there are indications of North Korea "digging holes and then filling them up with dirt" and that such activity is suggestive of underground test preparations. But he added, "The North Koreans are letting the U.S. see what they want us to see."--SPA1317 Local Time 1017 GMT www.spa.gov.sa/260496
