Police officers stand guard at the scene of a reported knife attack at Notre Dame church in Nice, France, October 29, 2020. France's national anti-terror prosecutors said Thursday they have opened a murder inquiry after a man killed three people at a basilica in central Nice and wounded several others. The city's mayor, Christian Estrosi, told journalists at the scene that the assailant, detained shortly afterwards by police, "kept repeating 'Allahu Akbar' (God is Greater) even while under medication." He added that President Emmanuel Macron would be arriving shortly in Nice. Photo by Eric Gaillard/Pool/ABACAPRESS.COM
