Every night, 14 year old Said scrambles down a narrow shaft leading to a tunnel. He'll spend the next eight hours digging without a break. It's claustrophobic, difficult work. The heat in the tunnel is unbearable and the more they advance, the harder it becomes to breathe. At any moment, the tunnel could come crashing down, burying them alive. That's not the only danger. "Sometime the Egyptians shoot gas into the tunnel that might kill us", states Ramdan. "There are risks of electric shocks and the Israelis might bomb the entrance". Since Hamas seized control of Gaza, the borders have been closed. The tunnels are the only way to import goods into the territory. "They're a gold mine!" states Said. But to his disgust, most of the profits go to other people. "We do all the work, then they swindle us", he complains. Once the tunnel is nearly ready, "other people will open it, do the trafficking and make more money than us". The money he does make will enable Said to support his entire family. But everytime he goes into the tunnel, he knows: "You are digging your own grave".
