SEOUL, South Korea (AP) - South Korean military officials have observed activities at the North's suspected nuclear test site that may be preparations for a second test, news reports said Saturday. Yonhap news agency, citing several unidentified military officials, said Seoul is keeping a close watch on the movements of trucks and soldiers at the Punggye-ri site in the country's remote northeast."It is clear there are movements at Punggye-ri after the (previous) nuclear test," one military official was quoted as saying. "We are closely monitoring to see if these are preparations for a second nuclear test."
Another official confirmed activities at the site, but said another test "is not believed to be imminent," according to Yonhap.
Meanwhile, more unidentified South Korean government officials said they are trying to confirm whether a new facility that has been built at the site could be part of preparations for a second nuclear test, the JoongAng Ilbo newspaper reported Saturday. South Korea's Defense Ministry said it could not confirm the reports, and the U.S. State Department refused to comment. A Pentagon spokesman, Air Force Maj. David Smith, said: "We don't discuss intelligence issues as a matter of policy."
