A knife attack in eastern France has killed one person and injured several others in an “act of Islamist terrorism,” French president Emmanuel Macron has said.
A man attacked local police officers in the city of Mulhouse shouting "Allahu Akbar" ("God is greatest") on Saturday afternoon, the PNAT prosecutor's office said in a statement.
A passer-by was killed trying to intervene, while three police officers were injured, the prosecutor's office added.
"It is without any doubt an act of Islamist terrorism," Macron told reporters on the sidelines of the annual French farm show, adding that the interior minister was on his way to Mulhouse.
He added that the government has "complete determination" to respond to the attack.
A 37-year-old Algerian man was arrested, the prosecutor's office said.
The victim was a 69-year-old Portuguese man, the anti-terrorism prosecutor's office said. Those wounded were police officers who intervened.
The suspect had been on a list of people flagged for radicalism, the regional prosecutor said.
France has been on high alert for extremist threats.
The French city of Mulhouse is near Germany and Switzerland in eastern France.
