One of three people stabbed to death in Nice has been named as church worker Vincent Loques.
Local politician Eric Ciotti tweeted a picture of Mr Loques dressed in a t-shirt, looking relaxed and smiling.
He said Mr Loques was a “devoted employee” of the Notre Dame church, where the attack took place.
One of the other victims – a woman – was decapitated.
La Parisien newspaper reported that Mr Loques was 55 and a father of two.
Members of the parish said he had been church warden for ten years, and was “expansive and sympathetic”.
Nice’s mayor, Christian Estrosi, tweeted that the attacker shouted “Allahu Akbar [God is greatest]” several times.
“Everything suggests a terrorist attack,” he added.
President Emmanuel Macron, who visited Nice on Thursday afternoon, said his country had been “attacked” and expressed the “support of France towards the Catholic community”.
He also pledged to deploy soldiers to protect key sites such as places of worship and schools.
French interior minister Gerald Darmanin encouraged people to stay away from the area with a police operation under way.
