Palestinians seeking refuge in southern Gaza say every day has become a desperate struggle to find food, water, medicine and working bathrooms. They often spend hours waiting in line for aid distributed by the U.N. Families also live in fear of Israeli airstrikes and the growing threat of diseases. Israel’s bombardment and ground invasion to eradicate Hamas have pushed almost all Palestinians toward Gaza’s southernmost city of Rafah. In nearly every plot of land that stretches west from the city, thousands of nylon tents have sprung up for those without a house to shelter in.
