Survivors reveal Superdome horror:
"They killed a man here last night," Steve Banka, 28, told the Reuters news agency before he left on Sunday.
"A young lady was being raped and stabbed. And the sounds of her screaming got to this man and so he ran out into the street to get help from troops, to try to flag down a passing truck of them."
"He jumped up on the truck's windscreen and they shot him dead," Mr Banka said.
