In western France, a policeman stabbed a woman, seriously injuring her and killed a man on Friday, local police said.
One suspect, still armed, was on the run after an attack in La Chapelle-sur-Erdre, near Nantes, and police have sent officers to pursue him, police said.
The BFMTV station said he took the police woman’s service weapon before fleeing.
A city official told AFP that students from the area’s primary and middle schools were kept indoors.
A source close to the investigation said the woman’s injuries were fatal.
Home Secretary Gerald Dermin was on his way to the scene, his ministry said.
La Chapelle-sur-Erdre is a small town of 20,000 inhabitants, north of Nantes, near the French Atlantic coast.
The attack came on the same day that Justice Minister Eric Dupund-Moretti urged French judges to show “perseverance” in dealing with people convicted of attacking police forces.
In a memo to investigate magistrates seen by AFP, he said all incidents of violence should go to criminal court.
French police have called for better security and harsher punishments for the attacks against them.
Earlier this month, African Eric Mason was shot dead while investigating activity at a known drug trafficking site in the southern city of Avignon.
Mason was killed in a jihadist attack in France on April 23, following the stabbing of police officer Stephanie Monform in the town of Ramboulette outside Paris.
