In the southern French town of Albi on Friday, a teacher was stabbed to death in front of her class by a student's mother. "This morning, a mother showed up with a knife and stabbed a 34-year-old teacher in front of her students, for reasons that will be determined by the investigation," Albi prosecutor Claude Derens told AFP. When he arrived she was in cardiac arrest and there were attempts underway to revive her. French President Francois Hollande has sent his education minister to the town to handle the government response. "All state services will be mobilized to take care of these children and the staff who witnessed this awful tragedy," Hollande said.
