Due to the nature of the conflict, exact numbers are hard to come by. But as of the end of 2014, the United Nations estimated that almost half of Syria's civilian population had been uprooted by the conflict with over 3 million Syrians becoming refugees and a further 6.5 million having become internally displaced people.
The immeasurable suffering of so many people is impossible to grasp. But in an effort to humanize those numbers, Associated Press photographer Muhammed Muheisen visited Syrian refugee camps in Jordan. In an effort to capture the life of refugees, Muheisen took a series of portraits of the displaced children of Syria.
We have featured some of Muheisen's most powerful photos below. Each photo features a quotation from the portrait's subject, as well as the subject's name, age, and home city in Syria.
