North Korea on Thursday reverted to hostile cold-war rhetoric, reneging on a pledge to stop cross-border mudslinging.
The North's Committee for the Peaceful Reunification of the Fatherland accused Park of "blabbering" like a peasant woman and described her as a "faithful servant and stooge of the United States."
At the Nuclear Security Summit in The Hague, Park warned on Monday that North Korean nuclear devices could end up in the hands of terrorists and vowed to strengthen cooperation with the U.S. and Japan to deal with the North's nuclear weapons.
The North said Park must learn to stop such reckless talk. This is the first time since the North proposed on Feb. 14 to stop ad-hominem attacks that Pyongyang took aim at Park directly and mentioned her by name.
A spokesman for the committee accused Park of "ignorance."
The government here expressed "strong regret" at the comments and urged the North to stop being "rude."
