Light at the end of the tunnel? Above, a 10-meter shaft leading to a tunnel is discovered by Israeli troops Aug. 4, 2004, at a home in Rafah. Tunnel openings are frequently hidden in homes—for example, in closets. As Israel continues its blockade to weaken Hamas’s control and respond to hostilities, tunnels have proliferated. Debate rages over whether Israel is creating a humanitarian crisis, or whether Palestinian militants are digging Gaza into a hole, metaphorically speaking, by resorting to violence. For the foreseeable future, though, it appears that authorities will continue playing whack-a-mole with Gaza’s underground economy.
