The suspect has been placed in custody. According to the investigation, this 37-year-old individual was on a list of people suspected of terrorism. Several sources indicate that he is originally from Algeria. A prior decision had been made regarding his house arrest and expulsion from France.
It has been reported that the attacker first assaulted municipal police officers while shouting, "Allahu Akbar!" A passerby who rushed to assist the police was fatally wounded by the assailant. The deceased was an elderly foreigner, a citizen of Portugal.
French President Emmanuel Macron referred to the incident as an "Islamist terrorist attack," emphasizing that there is no doubt about it.
The events unfolded during a demonstration in support of the Democratic Republic of the Congo, in a busy area of Mulhouse. The police had deployed security in light of this event.
