SEOUL, South Korea (AP) — South Korea expressed outrage Monday over a rhetorical attack on President Park Geun-hye by the North Korean government that likened her to a prostitute in a tirade far exceeding even the North's often strident standards. The statement issued by the North's Committee for the Peaceful Reunification of Korea expressed anger over President Barack Obama's visit to Seoul last week. In a statement of its own, South Korea's Unification Ministry strongly criticized the comments, saying they were immoral and contained words that were unacceptable.
