French President Emmanuel Macron has said he can understand why Muslims were shocked by controversial cartoons depicting the Prophet Muhammad.
But, in an interview with broadcaster Al Jazeera, he said he could never accept the issue justified violence.
It comes after Thursday’s deadly knife attack on a church in Nice, the third suspected Islamist attack in the country in little more than a month.
A row has been growing with some Muslim countries over issue of the cartoons.
Some have urged a boycott of French products as Mr Macron has defended the right to use the images in the context of freedom of speech.
Earlier this month a teacher was beheaded in a Paris suburb after showing cartoons of the Prophet Muhammad to some of his pupils.
Meanwhile Tunisia’s state news agency is reporting that two people have been detained there for questioning in connection with the attack in Nice, which was carried out by a Tunisian man.
France’s interior minister has said more militant attacks are likely.
On Saturday an Orthodox priest was shot and wounded in the city of Lyon, though no details about the attacker are known as yet.
What did Mr Macron say?
The French president said he believed strong reactions had come from Muslim nations because people had mistakenly thought that he supported the cartoons, or even that they had been created by the French state.
“I understand the sentiments being expressed and I respect them. But you must understand my role right now, it’s to do two things: to promote calm and also to protect these rights,” he said, referring to the freedom of expression of those who created the cartoons.
“Today in the world there are people who distort Islam and in the name of this religion that they claim to defend, they kill, they slaughter… today there is violence practised by some extremist movements and individuals in the name of Islam.”
Mr Macron also said a boycott of French goods proposed amid anger at the cartoons was “unworthy” and “unacceptable”.
What is the context of Mr Macron’s remarks?
France has raised its national security alert to the highest level, with security increased at places of worship and schools across the country.
Earlier this month teacher Samuel Paty was beheaded in a Paris suburb after showing controversial cartoons of the Prophet Muhammad to some of his pupils.
Responding to the series of attacks, Mr Macron said France would never give in to violence.
The issue has led to tension with some Muslim-majority countries, with effigies of the French leader burnt in Bangladesh and a war of words with Turkish President Recep Tayyip Erdogan, who questioned Mr Macron’s mental health.
