The video is via The Daily Mail. The Blaze points out that some women out in front of the cafe had a miraculous intervention:

• A particularly chilling moment in the video appeared to show the Islamist gunman aim his AK-47 point blank at a woman hiding under an outdoor table. After trying to fire unsuccessfully – either because the gun jammed or ran out of ammunition – the gunman walked away, allowing the woman to escape.

Wow.
