A government source has denied any sign of a second nuclear test by North Korea at the suspected test site in Kilju County, North Hamgyeong Province.

The source on Tuesday said the recent Korea-U.S. Military Committee Meeting examined intelligence on a possible second test, but found no particular signs even in suspected test areas.

The official said that joint intelligence authorities are closely watching several suspected sites, but movements of cars and personnel in recent days do not differ much from those detected earlier in the month.
