Twenty-one year old computer engineering student Shayma Ahmed used to live in a house with concrete walls. She'd drive to campus each day in a car. Now, home is a tent. Her only means of transport is a donkey cart that winds through streets of rubble in the central Gaza city of Deir al Balah. She tells host Marco Werman about the immeasurable sorrow the past year has brought her family and friends.
