Most remaining South Korean workers at a troubled joint industrial zone in North Korea returned home today after Seoul ordered a pullout following months of tensions.
Forty-three workers from Kaesong -- once a rare symbol of inter-Korean cooperation -- crossed back over the world's most heavily militarised frontier, according to Seoul's Unification Ministry.
But seven supervisors remained for talks with the North Koreans about unresolved administrative issues such as the wages of local workers, according to the ministry, which did not say when they were expected to return.
The evacuation raises the prospect of the permanent closure of the industrial park, the last point of contact between the two Koreas and a key source of income for Kim Jong-Un's isolated regime.
South Korean companies with factories at the site have expressed shock at the sudden pullout.
The complex is the victim of escalating tensions triggered by a nuclear test by the North in February, which has been followed by a series of bellicose threats of nuclear war and missile tests by Kim Jong-Un's regime.
The South's Unification Ministry played down concerns about the seven remaining employees, who work for the Kaesong Industrial District Management Committee and telecoms company KT Corp.
"We believe there is no chance of South Korean officials being held as hostages because both sides have been locked in talks on specific and practical issues since Friday," said ministry spokeswoman Park Soo-Jin.
"North Korea did not raise such issues suddenly to block them from crossing the border. We hope both sides will narrow their differences soon."
Seoul announced on Friday that it had decided to pull all employees from Kaesong after Pyongyang blocked access to the site and refused to open talks on restarting the stalled operations.
South Korean Foreign Minister Yun Byung-Se told a forum in Seoul that "the window of dialogue is still open" on Kaesong, according to the South's Yonhap news agency.
But some observers believe the shutting down of the complex would be permanent as the factory equipment there would fall into disrepair and the firms would soon lose their customers.
