Gaza has become "a much darker reality than anyone ever thought possible". That's the description from a spokesman for the United Nations Children's Fund, UNICEF. James Elder, who was in Gaza himself last week, told us how the people of the enclave are now able to live on just 15 percent of the land. They have lost their homes, their livelihoods and often many family members and friends. As the threat of widespread disease continues to rear its head, Elder spoke to us in Perspective.
