On 5 and 6 December, security services in Addis Ababa arrested an estimated 90 people during attempts to stage a demonstration by a coalition of nine opposition political parties. The arrests are the latest manifestation of the authorities’ hostility towards the political opposition ahead of the general election scheduled for May 2015. The Ethiopian authorities must ensure the immediate and unconditional release of those arrested for peaceful participation in, or the organization of, the demonstration, and all others imprisoned in Ethiopia for the peaceful expression of their political opinion.
