South Korea believes about 500 of its soldiers are alive and have been held in the North since the end of the Korean War in 1953, Yonhap News agency reported.
The South Korean Parliament Monday passed a resolution calling on the North to send Korean war prisoners back home instantly and to "accept Seoul's request for cooperation to resolve relevant issues."
The resolution, adopted by the Foreign Affairs and Unification Committee of the National Assembly, comes on the eve of the 60th anniversary of the Armistice Agreement that ended the Korean war.
"Considering the fact that most of the prisoners there are more than 80 years old now, the [South Korean] government has no luxury to sit idle," the resolution said.
