Al Jazeera television has said it will not broadcast video footage showing the murders committed in southwest France by Mohamed Merah.
President Sarkozy had publicly appealed for the film not to be aired. Al Jazeera said it added no new information and had passed it onto the police, declining requests from other media organisations for copies.
In one of the murders, Merah reportedly grabbed a small girl by the hair as he shot her at point-blank range. He strapped a camera to his chest as he killed three Jewish children, a rabbi and three soldiers.
The memory stick containing the video was posted from a small town outside Toulouse, while Merah was under siege. The pictures had been re-edited, adding Koranic verses.
The gunman’s family have decided to have him buried in his parents’ native Algeria. His father’s threat to sue the French state over his son’s death has been roundly condemned.
He believes his son could have been captured alive.
The French foreign minister said “if I was the father of a monster I would shut my mouth in shame”.
Merah was shot dead last week after a 33-hour siege in Toulouse. Investigators are said to be looking for a “third man” who may have provided logistical help. The gunman’s brother who’s in custody is being probed as an accomplice.
