The United States has condemned descriptions in North Korean state media of President Barack Obama as a "crossbreed" and a "wicked black monkey".
A spokeswoman in Washington DC said the comments were "ugly and disrespectful".
The Korea Central News Agency had released stories that graphically described the US leader as a "monkey" in comments by North Koreans in the days after he paid a state visit to South Korea.
"How Obama looks makes me disgusted," said Kang Hyuk, a worker at the Chollima Ironworks Factory, in a translation by the NK News website.
"As I watch him more closely, I realise that he looks like an African native monkey with a black face, gaunt grey eyes, cavate [sic] nostrils, plump mouth and hairy, rough ears.
"He acts like a monkey with a red bum, irrationally eating everything," Mr Kang added. "Africa's national zoo will be the perfect place for Obama to live, licking breadcrumbs thrown by visitors." » | Julian Ryall in Tokyo | Friday, May 09, 2014
