French authorities said Tuesday the gunman that killed a rabbi and three young children in an attack may have filmed his actions.
Claude Guéant, French interior minister, told a French radio station that surveillance footage from the Jewish school's security cameras showed what appeared to be a video camera strapped to the gunman's chest, the New York Times said.
With the nation's terrorism alert at its highest level - "scarlet" - the French authorities pursued a broad and high-profile search on Tuesday for the assailant, but Guéant said little was known about him.
The attack has been linked to two earlier shootings of French paratroopers, with the police saying that the same gun, a .45-caliber automatic pistol, was used in all three assaults and the attacks were carried out the same way - a man on a powerful motorbike who killed and then fled. The soldiers were all Arab or black, and appeared to have been targeted specifically, witnesses said.
"We are faced with an individual who targets his victims specifically," said Élisabeth Allannic, a spokeswoman for the Paris prosecutor's office, which is handling the investigation. "He targets his victims for what they represent."
Authorities released a photo of some of the victims, Rabbi Jonathan Sandler and his two sons, Ariel and Gabriel, who were killed in the attack, The Daily Beast said. Miriam Monsonego, 7, was also killed in the attack.
The bodies of at least three of Monday's four victims were to be flown Tuesday to Israel for burial, said Nicole Yardeni, who leads the regional branch of the Crif, France's most prominent Jewish association.
President Nicolas Sarkozy has called the shooting a "national tragedy" and ordered a minute's silence at schools across France at 11 a.m., the Times said.
