PARIS (AP) — Police say the mother of a pupil at a French pre-school has stabbed a teacher to death in front of her class of 5 and 6-year-olds on the last day of the school year.

French President Francois Hollande (frahn-SWAH' oh-LAWND') is expressing outrage at what he calls "this abominable drama" and has sent the education minister to the school in Albi in southern France.

A police official in Albi says the mother attacked the teacher this morning at the pre-school. Police have not commented on possible motives for the attack.
