As civil society leader Osman Kavala marks one year in Turkey’s highest security prison, Amnesty International and Human Rights Watch renewed their call for his immediate and unconditional release. One year on since a court ruled that Osman Kavala be remanded in Silivri prison near Istanbul, no indictment outlining the precise charges against him has yet been issued by the prosecuting authorities. Neither Osman Kavala, nor his family or lawyers have been shown the evidence to back up the vague allegations levelled against him, allegations which form the basis of his prolonged and punitive prison detention.
