The RCMP is analyzing a video recorded by Michael Zehaf-Bibeau shortly before he killed a reservist at the National War Memorial and shot his way into the Parliament buildings last week, the police force said in a statement Sunday.

“The RCMP has identified persuasive evidence that Michael Zehaf-Bibeau’s attack was driven by ideological and political motives,” RCMP Comm. Bob Paulson said in his second update on the Ottawa terrorist attack.

“Zehaf-Bibeau had prepared a video recording of himself just prior to conducting this attack. The RCMP is conducting a detailed analysis of the video for evidence and intelligence. You must understand that we cannot release this video at this time and I would ask for your patience in this regard.”
