A prominent critic of the Rwandan government has been arrested after being abducted in Dubai and taken back to Rwanda to face charges. Paul Rusesabagina is best known for being portrayed in the film “Hotel Rwanda,” which tells the story of how he saved 1,200 Rwandans during the 1994 genocide by sheltering them in a hotel he managed. Rusesabagina has lived in exile for years in Belgium and the United States.
