in this Monday, July 7, 2014 file photo, people shop at a market in the northern city of Mosul, Iraq. It’s becoming more expensive to live in the self-styled caliphate envisioned by the Islamic State group as militant-held cities grow increasingly isolated, impeding access to basic goods and services.
