In April 2014 BBC Trending covered the arrest of six bloggers and three journalists in Ethiopia. The bloggers are part of a group known as Zone 9, and are well known for campaigning around censorship and human rights issues in Ethiopia. Ten months on from their arrest, the hashtag #Free Zone9 Bloggers continues to be used in the country as the trials continue.
That's not typical - campaigning hashtags often tail off over time. This one is being kept alive by activists both inside and out of Ethiopia who are challenging the government's decision. The total number of tweets is still only in the tens of thousands, but that is enough to be noticed on the global map (Twitter does not produce an official trending topics list for Ethiopia).
Why are they so focused on social media? It certainly isn't the best way to reach the Ethiopian people: the internet is estimated to reach just over 1% of the population there. But it does allow them to network with the global blogging fraternity and the international media. Recently a blog began in support of the nine prisoners, and to report on the hearings. A campaign video has also been released in which complaints are raised over the conditions of Kalinto prison and Kality prison, where the bloggers are being held.
These complaints include torture, unlawful interrogation tactics and poor living conditions. The Ethiopian Embassy in London told BBC Trending that allegations of torture and unlawful interrogation tactics are unfounded, and that they have taken a series of measures "in collaboration with stakeholders, including civil society, to improve the conditions of prisons". They say the nine individuals are charged with "undermining the constitutional order, inciting violence and advocating the use of force to overthrow the legitimate government." They are also accused of working with an organisation proscribed by the Ethiopian Parliament as a terrorist organisation. However, activists in support of the group maintain that Zone 9's actions were constitutional.
