"They are killing everyone they meet," he said. "Over there is a slaughterhouse. It's not a joke. It's a slaughterhouse. No one is in Benghazi now. Shooting is everywhere, all shots in the head and the chest."

The Tunisian expatriates told ABC News they were leaving both because of the violence -- telling stories of gunfire in the night -- and because of fear that Gadhafi has stirred anger at foreigners in his country.
