Paris attack survivor tells story

A survivor of the slaughter inside the concert hall is telling his story.

Denis Plaud told the following to reporters:

"I was upstairs. The policemen were telling us how to go. There was, especially on the ground floor, a lot of dead bodies and blood. Some people had to stay for several hours among dead corpses and they went out covered with blood. I think I was quite lucky to be upstairs. Most of the killing was downstairs because the place was really, really crowded."

Police rushed blood-stained survivors to a yard for aid.
