Pyongyang, August 25 (KCNA) -- Some twenty small arms including carbines, M-1 rifles and machine guns were unearthed in a south Korean school on Monday, said the south Korean MBC (Munhwa Broadcasting Corporation).

The military said the arms, found on the campus of a girls' middle school in Chongju, North Chungchong Province, are believed to date back to the Korean war (1950-1953) in view of their erosion.
