Seoul has taken a hard stance on Ukraine disclosing the transfer of two soldiers captured fighting for Russia, warning that their families could be targeted by Pyongyang.
North Korea is known to retaliate against defectors and their families, Euronews reported.
Both POWs are identifiable as they had been photographed by South Korean media before their arrival to the South.
The POWs were captured by Ukrainian forces early last year after being deployed alongside thousands of North Korean troops to support Russia's war against Ukraine, in exchange for economic and military assistance to Pyongyang.
