The mass media in Burkina Faso consists of print media and state-supported radio, news, and television stations, along with several private broadcasters with programs consisting of sports, music, cultural, or religious themes. Government media influence and control In Burkina Faso, the authorities have periodically announced their respect for freedom of the media; RadioDiffusion Burkina states that the country's transmission facilities are open to "all political and social sensibilities". Privately owned newspapers, television, and radio stations are allowed. The Information Code of 1987 provided for freedom of speech and freedom of the press. However, there are serious exceptions to this freedom. A revised Information Code, implemented in 1993, allows for news outlets to be arbitrarily banned if "accused of endangering national security or distributing false news." The Conseil Supérieur de la Communication (CSC), the government's Supreme Council on Information, is charged with media oversight. Additionally, non-legal constraints on critics of the government exist. The mission statement of the state-owned Radiodiffusion-Télévision du Burkina (RTB) declares that its broadcast networks are "adapted" to the requirements of law and democratic pluralism. It emphasizes that journalists using public mediums are obliged to "respect the principles of ethics" with regards to "objectivity and balance" in the treatment of information. Acts against journalists and government critics In December 1998, journalist Norbert Zongo was murdered by unknown assailants, and his body burned. Since his death, the tragedy has been used by unidentified persons leaving 'warnings' to journalists and broadcast commentators critical of alleged government injustice and/or corruption. In August 2002, police in Burkina Faso arrested Newton Ahmed Barry, editor-in-chief of the private monthly L'Evénement. Barry was held for two days before being released without charge. Mathieu N’do, managing editor of the opposition weekly San Finna, was detained by authorities on November 5, 2004, as he was returning from Ivory Coast. His detention may have been linked to his journalistic work, which is often critical of the Burkina Faso government. In particular, N’do has been an outspoken critic of government policy in Ivory Coast where Burkina Faso has been accused of arming the rebellion. N'do was held incommunicado by Burkina Faso's national security service in Ouagadougou until being released without charge on November 11. Since the death of Norbert Zongo, several protests regarding the Zongo investigation and treatment of journalists have been prevented or dispersed by government police and security forces.
