KIGALI, Sept 20 (Reuters) - A Rwandan court on Monday sentenced Paul Rusesabagina, a one-time hotel manager portrayed as a hero in a Hollywood film about the 1994 genocide, to 25 years in prison after he was found guilty of terror-related charges. "Rusesabagina is guilty of being a member of a terror group and participating in terror activities," judge Beatrice Mukamurenzi said. "His act of terrorism led to death."
