Militant members and sympathizers of the Islamic State of Iraq and Syria (ISIS) have circulated pictures of what they said was the passport of the so-called "caliphate" declared last week by the militant group.

The "State of the Islamic Caliphate" appears to be inscribed at the top of the purported passport. At the bottom, it says: "The holder of the passport if harmed we will deploy armies for his service."

ISIS reportedly said the new document will be distributed to 11,000 citizens living in cities bordering Iraq and Syria.
