In Turkey, four journalists and a writer have been charged with being involved in a plot to overthrow the government.
All of the men have been fiercely critical of the administration in their writing. They are accused of membership of a terrorist group and inciting hatred.
The US, human rights groups and the European Union - which Turkey wants to join - had already expressed concerns about the Turkish government’s commitment to press freedom and democracy.
Human Rights Watch said the latest arrests had a ‘chilling effect‘ on free speech in Turkey.
But prosecutor Zekeriya Öz said the action had nothing to do with the men’s writings.
He is heading an investigation into the shadowy ultra-nationalist Ergenekon group over allegations that its members are plotting to bring down the government.
Hundreds of people have been charged as part of the inquiry.
