Powerline gives more info on the Gaza tunnels - how Hamas killed those who worked on the system.
Hamas reportedly executed dozens more diggers in the past few weeks out of fear that they would provide information to Israel about where the tunnels are located.
The executions were reported on an Israeli military blog, based on statements by Palestinians involved in the digging. The Times of Israel could not independently confirm the report. But who can doubt that Hamas, which reportedly spent 40 percent of its budget on the digging and used child labor, would take the most extreme measures to keep the locations secret from Israel?
Israelis head to underground shelters to live.
In Gaza, going underground means you're going to die.
