The not-so-diplomatic war of words between North Korea and the US has taken a strange turn.
North Korea's state-run Korean Central News Agency (KCNA) has called Nikki Haley, the US ambassador to the United Nations, a "political prostitute... crazily swishing her skirt".
"Nikki should be careful with her tongue though she might be a blind fool," a newsreader for KCNA said. "The US administration will have to pay a dear price for her tongue-lashing."

It comes after Ms Haley accused the North Koreans of "begging for war" after conducting a massive nuclear test.
The KCNA said it was a "hysteric fit".
"She is crazily swishing her skirt, playing the flagship role in the Trump administration's hideous sanctions and pressure racket."
The language is reminiscent of a warning KCNA issued to Australian Foreign Minister Julie Bishop earlier this year.
"The Australian Foreign Minister had better think twice about the consequences to be entailed by her reckless tongue-lashing before flattering the US," the KCNA said.
Another nuclear test is feared this weekend, as North Korea celebrates the anniversary of its founding.
