SEOUL, South Korea (AP) -- North Korea plans to allow six detained South Koreans to return home, officials in Seoul said Thursday.
Pyongyang's Red Cross sent a letter to the South saying the South Koreans will cross over the heavily armed border at the so-called truce village of Panmunjom on Friday, according to a short statement from the South's Unification Ministry, which is responsible for cross-border ties.
The statement says Seoul plans to accept the South Koreans and investigate how they entered North Korea. Their identities weren't immediately clear.
It's also unclear whether any of the six were among the four South Koreans the North said it was investigating in 2010 for illegally entering the country. Seoul says it has repeatedly asked Pyongyang to confirm those citizens' identities but has received no reply.
Relations on the Korean Peninsula have recently improved, but the rival Koreas were trading threats of war in March and April. They've since reopened operations at a jointly run industrial park in the North.
South Koreans visiting North Korea without government approval can be punished by up to 10 years in prison under South Korea's National Security Law.
The Korean Peninsula is still technically in a state of war because the 1950-53 Korean War ended in a truce, not a peace treaty.
