North Korea still holds Seoul’s POWs

It has been nearly 60 years since the end of the Korean War.
 
But South Korea says the North Korean government still refuses to acknowledge the existence of prisoners of war (POWs) held in the north.
 
And time is running out for POWs to be reunited with their families living in the south.
