According to a report by Human Rights Watch, "Since President Ahmadinejad came to power, treatment of detainees has worsened in Evin Prison as well as in detention centers operated clandestinely by the Judiciary, the Ministry of Information, and the Islamic Revolutionary Guard Corps." Human Rights Watch also has stated, "Respect for basic human rights in Iran, especially freedom of expression and assembly, deteriorated in 2006. The government routinely tortures and mistreats detained dissidents, including through prolonged solitary confinement." Human Rights Watch described the source of human rights violations in contemporary Iran as coming from the Judiciary, accountable to Ali Khamenei, and from members directly appointed by Ahmadinejad.
