Kim Young-chol, head of a high-level North Korean delegation, and other delegates arrive at a Seoul hotel on Feb. 25, 2018, for a three-day visit to attend the closing ceremony of the PyeongChang Winter Olympics and meet with Seoul officials. Kim, a key party official handling inter-Korean affairs, is suspected of having orchestrated the North's torpedoing of the corvette Cheonan in March 2010, killing 46 South Korean sailors.
