Khan Younis, Gaza Strip (AP) — In their bare-bones tent in southern Gaza, Mostafa Shaaban built his family’s makeshift toilet behind a curtain in a corner. He dug a shallow pit in the sandy soil, poured a concrete slab around it, fixed a bottomless bucket over the hole, then topped it off with a battered, plastic toilet seat.

It reeks with a foul odor and buzzes with flies and mosquitoes only a few feet from where they sleep and prepare meals. Every week, Shaaban has to dig the sewage sludge out of the pit. But at least it’s more private than the fetid communal latrines used by hundreds of other people in their sprawling tent camp.
