The suspect was later reportedly shot dead by police. While his motives are expected to be fully determined and confirmed by police, the prosecutor’s office on counterterrorism has launched an investigation into the attack.
Separately, media reported that Daesh* terrorist group has claimed responsibility for the stabbing attack.
Last November French President Emmanuel Macron signed an anti-terror law in order to replace a state of emergency, imposed after terror attacks in Paris in November 2015 that killed 139 people. The law led to a heated discussion in the parliament, while the UN experts criticized it for "vague wording."
According to French media, jihadist attacks have killed over 245 people in France over the past three years.
