A year after its blitz across Iraq and Syria, Islamic State group creates nation of fear

In the Islamic State's realm, a document testifying that one has "repented" from a heretical past must be carried at all times and it can mean the difference between life and death. Abdullah learned that not long after the extremists took over his home village. (AP Photo/Bram Janssen) (The Associated Press)

Iraqis and Syrians who lived under territories held by the Islamic State group say that the extremists have entrenched their rule into a quasi-nation over the past year.

More than 20 people interviewed by The Associated Press describe an extensive bureaucracy run by the group to impose control and spread their radical version of Islamic Shariah law over their territories bridging Iraq and Syria.

Those interviewed provided an array of documents, including copies of "repentance cards" that former government loyalists and police must carry to show they abandoned their "heretical" past.
