The land down under: Except for basic humanitarian supplies, Israel has blockaded the flow of goods into Gaza since June 2007, when Hamas, a militant Islamist group committed to Israels destruction, ousted its more secular rival, Fatah. The blockade has led to a new economic structure -- a literal underground economy in which everything from food to gasoline to underwear is illicitly imported from Egypt via underground tunnels into Rafah, which sits on Egypts border at the Sinai Peninsula. Above, Palestinian men pull a bag of smuggled food, milk, and other supplies from an underground tunnel linking Rafah, in southern Gaza, to Egypt, on June 27.
