CBS News spoke recently with an Israeli soldier who has questioned the military’s tactics. Tommy — not his real name, as he agreed to speak with CBS News on the condition of anonymity — fought in Gaza for the IDF, and his account of the tactics used raises some serious questions.

“We’ve burned down buildings for no reasons, which is violating the international law, of course,” he told CBS News. “…And we used human shields as protection.”

Tommy said his commander ordered his unit to use Gazan civilians to search buildings for explosives instead of dogs.

“They were Palestinian,” he said. “We sent them in first to see if the building was clear and check for booby traps…They were trembling and shaking.”

“We talked to our commander, and we asked him to stop doing it,” Tommy said, but they were ordered to continue. He told CBS News it was policy.
