Newly released footage of the gunman who killed a soldier at Canada's national war memorial and stormed Parliament before being gunned down shows him asking Allah to praise his actions before last October's attack.

Police on Friday released 18 additional seconds of gunman Michael Zehaf Bibeau's video message. That footage had been edited out of an earlier version released last October to give investigators time to analyze the dialect of Arabic he was speaking.

Zehaf-Bibeau shot Cpl. Nathan Cirillo, 24, to death while he was standing guard at the national war memorial. Zehaf-Bibeau was eventually gunned down inside Parliament.

In the newly released footage, Zehaf Bibeau asks Allah to ease his upcoming task and curses those he is targeting.
