The U.N. has sent over 50 requests to the North Korean government since last year seeking information about its role in enforced or involuntary disappearances but has yet to receive a response, according to a U.N. working group on Wednesday.

In its annual report, U.N. Working Group on Enforced Disappearance (WGEID) states that Pyongyang’s silence toward the 55 new requests sent between May 2021 and May 2022 demonstrates “the persistent lack of cooperation from the Government” on clarifying the fate and whereabouts of disappeared persons.
