The producers of Comedy Central's "South Park" are apparently undeterred by a warning of violence.
Wednesday's episode of the animated series included the Prophet Muhammad as a character, despite a warning from a radical Muslim group that producers Trey Parker and Matt Stone could be killed.
The character's face was obscured by a black box because Muslims consider a physical representation of their prophet to be blasphemous.
A similar episode last week angered the New York group Revolution Muslim. It posted a warning on its website that Parker and Stone could face the same fate as a Dutch filmmaker who was killed after making a movie about a woman who rejected Muhammad's teachings.
Last week the character was hidden in a bear costume. When the costume was removed this week, Santa Claus appeared.
