The interior minister of France reports that at least six very young children have been stabbed in a park close to Lake Annecy.
According to Gérald Darmanin, police surrounded and detained the assailant.
According to reports, at least two of the kids, who were around three years old, were in a critical condition.
The French prime minister, Élisabeth Borne, is en route to the scene and regional deputy Antoine Armand called the attack "abominable.".
Thoughts were with the victims and their loved ones, Mr. Armand said, adding that authorities were looking into the matter and knew "very little.".
According to reports from Le Parisien, BFM TV, and AFP citing police sources, the suspect is thought to be a Syrian seeking asylum.
Roads are blocked near the attack site, and the National Assembly of France has observed a minute of silence.
According to a tweet from President Emmanuel Macron, the country is in "shock," and several children and an adult are in critical condition.
