 As of March 2015, the Islamic State of Iraq and the Levant (or ISIS/ISIL, Daesh), a Salafi jihadi extremist militant group and self-proclaimed caliphate and Islamic state led by Sunni Arabs from Iraq and Syria, had control over territory occupied by ten million people in Iraq and Syria, as well as limited territorial control in some other countries.The United Nations has held ISIS responsible for human rights abuses and war crimes, and Amnesty International has reported ethnic cleansing by the group on a "historic scale", including attacks on Shia Muslims.According to Shia rights watch, in 2014 ISIS forces killed over 1,700 Shia civilians at Camp Speicher in Tikrit Iraq, and 670 Shia prisoners at the detention facility on the outskirts of Mosul.
