North Korea has compared South Korean president to 'crafty prostitute' in thrall to her 'pimp' Barack Obama.
The North also described Park Geun-hye as America's 'comfort woman'.
According to the Guardian, the comments were issued by the Committee for the Peaceful Reunification of Korea (CPRK), which handles cross-border affairs, following President Obama's two-day visit to Seoul.
He arrived in Malaysia on Sunday for the penultimate stop on his four-nation tour of Asia.
While Pyongyang is known for its aggressive rhetoric, recent remarks have been unusually personal.
The committee also accused Obama of being 'utterly indifferent to the sorrow of South Koreans' over the sinking of the Sewol ferry.
The statement also suggested that Park would be assassinated like her father, the late South Korean dictator Park Chung-hee, the report added.
