North Korea allowed only six people to return to South Korea from a joint industrial complex in the North on Saturday, a day after Pyongyang closed the inter-Korean border for the second time in the last week.

Some 600 South Korean workers were prevented from traveling to the Gaeseong Industrial Complex and 250 from returning home from the North's border city on Friday.

Three Chinese, one Australian and two South Korean were permitted entry back into South Korea.

One of them, Kim Hyang-hee, who will get married tomorrow, said she was able to return to the South by making a request to the Gaeseong Industrial Complex management office in the North’s border city.

On Monday, North Korea cut inter-Korean military hotlines and blocked border traffic in protest of the annual South Korea-U.S. joint military exercises currently under way, but lifted the travel ban the following day.

Currently, some 760 South Koreans are staying in the North --- some 730 at the Gaeseong complex and 30 at the Mount Geumgang resort near the east coast.
