Wastewater has already caused death to tunnellers in Gaza.

But to make peace accords stick between Israel and Egypt, Egypt’s new government has no choice but to enforce the borders between Gaza and Egypt-controlled Sinai. The tunnels are not only used for goods into Gaza, they are used to transport weapons.
