The Kazakh poet Aron Atabek has been in prison since 2007. He has been placed in solitary confinement for two years as punishment for writing a book that criticises President Nursultan Nazarbayev, and is due for return to the general prison population at the end of 2014. He has previously spent two years in solitary confinement for refusing to wear a prison uniform: one third of his incarceration so far has been spent in isolation. Both the UN Human Rights Committee and the UN Committee against Torture have concluded that prolonged solitary confinement may amount to torture.
