Hungry for help: Children at the Rafah refugee camp on Oct. 16 pack food aid distributed by the U.N. Relief and Works Agency. Some 750,000 Gazans depend on U.N. food aid. On Nov. 13, the United Nations agency ran out of food; Israel hadn’t allowed trucks with relief supplies to enter since Nov. 4 in response to rocket and mortar firing by Gazan militants into southern Israel. Trucks were allowed in Nov. 17, but the border was closed again Nov. 18 after rockets were fired into Israel.
