Lawmakers from South Korea's main opposition party Liberty Korea failed to prevent the arrival of a North Korean Winter Olympics delegation led by General Kim Yong Chol after leading a protest at the Unification Bridge on Saturday and Sunday.

The sit-in protest, which was conducted at a location Kim's delegation would normally have to pass after crossing the overland border on Sunday morning, was organized due to his alleged involvement in the orchestration of the sinking of South Korea's Cheonan naval corvette in 2010.
