In the French city of Annecy in the east of the country, a Syrian with refugee status attacked with a knife a group of children aged about 3 years.
This is reported by the BFMTV channel.
The attack happened on Thursday morning near the lake in the city park. Initially, five wounded were reported, four of whom were children.
The condition of at least four victims is extremely serious.
The head of the French Ministry of Internal Affairs, Gérald Darmanin, announced that the suspect in the attack had been arrested.
As it turned out, the attacker is an asylum seeker from Syria born in 1991. He applied for asylum in France last November, but was granted refugee status in Sweden in April this year.
French President Emmanuel Macron condemned the attack as "absolute cowardice" in a tweet.
"Children and adults are between life and death. The nation is in shock. Our thoughts are with them, as well as their families and rescue services," he also wrote.
Prime Minister Elizabeth Bourne went to the scene, as did several other French officials.
Politicians of various views condemned the attack. The attacker's motives are still unknown.
