SECURITY RAMPED UP
French CRS (Compagnies Republicaines de Securite) police officers patrol near the entrance of Le Bois d’Aulne middle school in Conflans-Sainte-Honorine, 30kms northwest of Paris, as the pupils are back to school after holidays, two weeks after a teacher was decapitated by an attacker. France honoured the teacher beheaded near his school by a suspected Islamist radical as millions of students returned to class after a spate of attacks that have put the country on edge.
