South Korea will cremate the body of a North Korean man found adrift off its western coast, after Pyongyang failed to respond to repeated offers to repatriate the remains.

“In the previous announcement, we informed that the handover would take place on Aug. 5, and if there is no response, the remains will be treated as unclaimed,” Seoul’s unification ministry told NK News on Tuesday. However, Pyongyang did not reply by the designated time of 3:00 p.m.
