North Korea scored poorly on efforts in nuclear arms reduction, nonproliferation and nuclear security in a report issued Monday by the Hiroshima Prefectural Government, which graded 31 nations.

The "Hiroshima Report" said that North Korea, which conducted its third nuclear test last February, scored negative points in nuclear arms reduction and nuclear security and zero in the field of nonproliferation.

The five major nuclear powers of Britain, China, France, Russia and the United States, meanwhile, were also slow in making progress on disarmament, according to the report, the second of its kind. The Hiroshima government began compiling the report last year, when it graded the arms reduction efforts of 19 nations.
