A second group of South Koreans are holding private meetings with their long-lost North Korean relatives on the second day of reunions at the North's Mount Geumgang.

A total 149 South Koreans are meeting with 237 of their kin from the North whom they haven't seen for half a century. Later in the day, they will take a tour around the Samilpo Lake near the mountain resort.

The South Korean group is slated to return home Friday.

Earlier on Tuesday, the first group of some 470 South Koreans returned to the South after wrapping up three days of reunions in the North.

The latest round of family reunions is the tenth since the historic inter-Korean summit in 2000.
