Eli Harel was an Israeli soldier in his early thirties when he was sent into Lebanon in 2006 to battle fighters from the Iranian-backed group Hezbollah in a bloody, largely inconclusive month-long war.

"There are booby traps everywhere," he told reporters. "People are popping up from tunnels. You have to be constantly on alert otherwise you will be dead."
