The Norwegian man charged with the twin attacks that claimed at least 92 lives in Norway apparently published a manifesto and video on the internet prior to the deadly acts, media reported late Saturday.
In addition to a 12-minute video uploaded on video-sharing site YouTube, the 32-year-old also published a 1,500-page manuscript titled "Declaration of independence of Europe," where he outlined his views, dpa quoted the broadcaster TV2 as reporting.
The video showed the man with an automatic weapon and wearing a diving suit adorned with a badge with the inscription "Marxist hunter." The video was titled Knights Templar 2083.
The manuscript slammed multiculturalism and stated how immigrants, especially Muslims, should be banished from Europe. It was signed with the name Andrew Berwick, likely a Anglicized version of the suspect's Norwegian name.
The suspect has been charged with shootings that have claimed at least 85 lives on Friday, as well as for a bombing hours earlier in central Oslo that killed seven people.
According to police sources quoted by TV2 and the online edition of daily VG, the suspect has admitted to publishing the material on the internet prior to Friday's attacks.
