Three people have been killed in a knife attack at a church in the French city of Nice. Nice Mayor Christian Estrosi said there had been a “terrorist attack at the heart of the Notre-Dame basilica”. One elderly victim who had come to pray was “virtually beheaded”. A suspect was shot and detained shortly afterwards. Mr Estrosi spoke of “Islamo-fascism” and that the suspect had “repeated endlessly ‘Allahu Akbar’ (God is greatest).” President Emmanuel Macron is on his way to the scene. France’s national anti-terror prosecutors have opened a murder inquiry.
