Shi’ite Turkmen families, who have fled the violence in Mosul, gather at a Shi’ite mosque in the town of Nahrawan, east of Baghdad, July 16, 2014. Baghdad has struggled to recapture territory from the insurgents who seized Mosul, Tikrit and other cities last month in a rapid offensive which threatens to fragment Iraq on ethnic and sectarian lines.
