People’s Daily Online on Wednesday deleted a story and 55-photo slide show that named Kim Jong-un, the young, chubby ruler of North Korea, the “Sexiest Man Alive of 2012.” The package by the People’s Daily Online, which is run by People’s Daily, the Communist Party mouthpiece, appeared to misinterpret a parody in The Onion, a satirical newspaper and Web site, about Mr. Kim being ranked the “sexiest man,” treating it as serious news. An editor at People’s Daily Online told The Associated Press on Wednesday that the news organization had now realized the Onion story was satire. The editor added that People’s Daily Online had picked up the story from the Web site of Guangming Daily, a major party newspaper. He Ning, an editor at Guangming Daily, said in an interview that she had picked up the article from another Web site and “had no idea that the news was satire.”
