Displaced Palestinians prepare food in front of the United Nations Relief and Works Agency (UNWRA) school at the Nuseirat refugee camp in the central Gaza Strip, amid ongoing battles between Israel and the militant group Hamas. "Life here is incredibly difficult, and we have endured a great deal. This is the harshest war of all," says Om Anas, from Beit Hanun in the northern part of the Gaza Strip. Due to the lack of space at the camp, in many cases, as in other camps, residents have had to add extra floors to their shelters for their families. IMAGES AND SOUNDBITES
