According to initial reports, the two others got out and attempted to hide underneath the car, but were shot by soldiers who feared they might be wearing explosive belts.

A taxi driver told Israel Radio he was on his way to Jerusalem when he noticed the suicide bomber.

"There was a huge explosion," he said. "I saw them pull the two [other] terrorists out of the car and force them to the ground. Apparently there was an explosive belt on one of them. After five or 10 minutes, I heard gunshots - apparently they shot at the terrorist."
