SEOUL, South Korea (AP) — South Korea has expressed outrage 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 and likened Park to a “despicable prostitute” with Obama as her pimp.

The North’s officials and state-run media frequently use flourishes of inflammatory rhetoric. It has called past South Korean presidents dogs, but has shown a particular penchant for insulting Park with sexist slurs.
