'We have nothing.' As Israel attacks Rafah, Palestinians are living in tents and searching for food

The tent camps stretch more than 16 kilometers (10 miles) along Gaza's coast, filling the beach and sprawling into empty lots, fields, and streets. Families dig trenches to use as toilets. Fathers search for food and water. Children dig through garbage and wrecked buildings for wood or cardboard for their mothers to burn for cooking.
