BEIT LAHIYA Gaza Strip (Reuters) - In a school in northern Gaza, scores of families sweat in cramped classrooms. Babies cry, while restless kids draw on chalkboards and worried parents give thanks for their relative safety.
They are among more than 50,000 civilians taken in by the main United Nations agency in Gaza, UNRWA, as they flee heavy shelling amid an Israeli ground offensive into the border areas of the Gaza Strip.
