In this Tuesday, May 13, 2014 photo, Palestinian refugees Fathiyeh Sattari, 62, and her son Hassan, 40, look at their photograph that was taken at the Rafah U.N. Relief and Works Agency, UNRWA, clinic in 1975, at their family home in Rafah Refugee Camp, the southern Gaza Strip. The UNWRA photo shows Sattari, her eyes wide with worry, as she presents her malnourished baby boy, Hassan, to a doctor. The picture is part of UNWRA's vast photo archive being digitized in Gaza and Denmark to preserve a record of one of the world's most entrenched refugee problems, created in what the Palestinians call the "Nakba," or “catastrophe”-- their uprooting in the war over Israel's 1948 creation.
