Relatives of Japanese abductees taken to North Korea in the 1970s and 1980s submitted Thursday 62 questions and points they consider suspicious in Pyongyang's latest explanation of the fates of their kin.

The relatives presented their questions and doubts in a 10-page paper submitted to the government.

It is their latest attempt to put to pressure on Tokyo to take tougher measures, including economic sanctions, to obtain more information from the reclusive state.
