Toulouse, France (CNN) -- The suspect in a deadly shooting spree at a Jewish school in France knows he is being hunted and might carry out another attack, Paris Chief Prosecutor Francois Molins warned Tuesday. He said the killer is "very determined" and has committed premeditated murders, targeting victims based on their race or religion. "The criminal is anti-Semitic or terrorist," Molins said. "One does not exclude the other." The shooting on Monday was the third fatal attack on minorities in southwest France in eight days. The region remains on scarlet alert, the highest level in France, after a teacher and three children -- two of them his own young sons -- were gunned down Monday at Ozar Hatorah, a Jewish school in Toulouse. The other victim, the daughter of the school's director, was killed in front of her father.
