Zoriah is an independent photojournalist, and although he’s not currently located in Gaza, his blog features some older images that are nonetheless important. This collection of photographs of the Hamas tunnel system is a must-see:

January 8 In August I was granted access to descend into and photograph a Hamas tunnel system, something that few local journalists, much less foreign press are allowed to see or document. Palestinians risk their lives working in the tunnels both for monetary reward and basic survival, so for me it was interesting to document the risks they take in order to dig and operate these tunnels. They have always been a risky operation and many people have lost their lives. Three people died in a tunnel collapse the day before I arrived to shoot this story and the tunnel I was supposed to visit collapsed on my trip down to Rafah from Gaza City.
