Palestinian tunnel diggers, wearing masks to conceal their identities, sit at the entrance to a smuggling tunnel in Rafah, in the southern Gaza Strip, on the border with Egypt, in this photo taken late Wednesday, Aug. 8, 2007. In underground darkness with stifling heat and limited air supply, Gazans are finding an antidote to their growing isolation: digging tunnels under their border with Egypt to smuggle everything from weapons to cigarettes to people.
