Internally displaced Iraqis at a camp outside Fallujah, Iraq, Monday, June 14, 2016. The U.N. estimates about 50,000 civilians are trapped inside the city and that 42,000 people have fled Fallujah since a military operation to retake the city began in late May. Organizations such as MSF and The Norwegian Refugee Council say the number of those who’ve fled is closer to 30,000, lower than the U.N. estimate. (AP Photo/Hadi Mizban)
