Despite constitutional guarantees for freedom of expression, journalists in Yemen face extraordinary risks. After the 2011 revolution the number of print and electronic media increased, but these gains were short lived. The breakdown of security, political crisis and open conflict mean that independent reporters are regularly subjected to censorship, threats and violence. At least 13 journalists have been killed in Yemen since 1992. In practice, state and non-state actors control the airwaves. Arbitrary detention and abduction of critical journalists is rife meaning that self-censorship is imperative to ensure survival. Furthermore, internet freedom is increasingly controlled by the authorities, depriving freedom of expression on the net. All of these factors combine to make Yemen one of the worst performing countries for media freedom in the world.
