The Yarmouk Camp is a primarily Palestinian refugee camp located in Syria that has been cut off and trapped from food and water from both ISIS and the Assad regime. The lighting in the photo I think is very appropriate to the general feeling and atmosphere of the situation where the back center of the photo is foggy and blurry, with the mass of people escaping from that center. The fogginess and blurriness I think is symbolic of the war and the bleakness of their situation.
