Thousands of Palestinians are fleeing south on foot with only what they can carry after running out of food and water in the north, a U.N. agency said Wednesday, as Israel said its troops were battling Hamas militants deep inside Gaza City.
Over 70% of Gaza's population of 2.3 million have already fled their homes, but the growing numbers making their way south point to an increasingly desperate situation in and around Gaza's largest city, which has come under heavy Israeli bombardment.
