The Islamic State-related Amaq news agency, citing a source, said Saturday an IS "soldier" executed the attack in Nice, France, on Thursday in response to the group's call to target the anti-IS alliance.
A truck rammed into a crowd marking the national day of France in Nice on Thursday evening, leaving at least 84 people dead.
The driver of the truck, identified as a 31-year-old French citizen of Tunisian origin, was shot dead by police and arms and grenades were found inside the vehicle.
