SEOUL (Reuters) - North Korea on Saturday called a recent CNN program depicting a public execution in the communist state a "sheer fabrication" and dismissed it as a ratings ploy by the U.S.-based broadcaster.North Korea takes any criticism of its internal affairs sensitively and brands it a part of U.S. conspiracy to topple the government of its leader, Kim Jong-il.CNN earlier this month broadcast a documentary, "Undercover in the Secret State," which among other images showed a grainy clip of what it called a public execution by firing squad of a man accused of helping a refugee cross into neighboring China."The video tape is full of sheer lies negating the popular and class nature and the democratic principle of the DPRK's laws and tarnishing its image from A to Z," the North's official KCNA news agency said in a commentary.DPRK is short for the North's official name, the Democratic People's Republic of Korea.
