South Korea has called on North Korea to explain why one of its soldiers shot dead last Friday an unarmed housewife holidaying at a resort in the North.
The incident occurred at the Mount Kumgang resort, a few kilometres north of the heavily fortified border.
The resort, opened in 1998 and visited by nearly two million South Koreans, was hailed as a milestone in reconciliation between the two states technically still at war.
The victim, 53-year-old Park Wang-ja, had left her hotel to watch the sunrise over the sea.
She had apparently strayed past fenced-off resort grounds and was shot by a North Korean sentry.
