The Islamic State of Iraq and the Levant (ISIL), also known as the Islamic State of Iraq and Syria (ISIS), Islamic State (IS), and by its Arabic language acronym Daesh, is a Salafi jihadist militant group that follows a fundamentalist, Wahhabi doctrine of Sunni Islam.

The group has been designated a terrorist organisation by the United Nations and many individual countries. ISIL is widely known for its videos of beheadings of both soldiers and civilians, including journalists and aid workers, and its destruction of cultural heritage sites. The United Nations holds ISIL responsible for human rights abuses and war crimes, and Amnesty International has charged the group with ethnic cleansing on a historic scale in northern Iraq.
