Al Jazeera receives videos allegedly filmed by Toulouse gunman
Video footage filmed by Mohamed Merah, who killed seven people in south-west France, has been received by al-Jazeera in Paris, police sources say.
A computer memory stick containing a montage of clips along with readings from the Koran was sent to the TV channel before being passed to police.
Merah, 23, was killed in a shoot-out with police last week.
His brother, Abdelkader Merah, has been charged with complicity in the murders, but denies the accusations.
The spate of shootings, which included the killing of three young children, shocked France.
The package sent to al-Jazeera was reportedly dated 21 March, the day police surrounded Merah's apartment, according to Le Parisien daily newspaper.
"Investigators are trying to find out whether the letter was posted Tuesday night by Mohamed Merah himself or by an accomplice Wednesday morning," Reuters quotes the newspaper as saying.
