SEOUL -- South Korean conservatives stepped up their opposition Friday to a visit by a North Korean official suspected of plotting deadly attacks on their country, creating a test for President Moon Jae-in's attempt to use the Olympics as an opening for dialogue.
The North's delegation to the Winter Olympics closing ceremony on Sunday will be led by ex-spymaster Kim Yong Chol, considered responsible for the 2010 sinking of South Korea's Cheonan naval ship.
