A delegation crosses from North to South Korea.
Cross-border traffic has been rare since relations on the peninsula cooled in 2008.
But this group, which includes the widow of former President Kim Dae-jung and Hyundai group chairwoman Hyun Jeong-eun, made the journey to pay their respects to the late leader Kim Jong-il.
They were received by his youngest son and successor Kim Jong-un on Tuesday.

"The lady delivered condolence messages and I was told that Kim Jong-un, Vice Chairman of National Defence Commission, said 'thank you for coming this far.'"
Meanwhile scuffles broke out between more than 100 anti-North Korea demonstrators and police in South Korea's capital Seoul.
The protesters are angry that a civic activist flew to Pyongyang recently, breaking the National Security Law banning unapproved trips to the North.
In another part of town a small group of pro-North demonstrators rallied to demand they be allowed to travel to pay their respects.
