Several French news organisations have said they will no longer publish photographs of people responsible for terrorist killings, to avoid bestowing "posthumous glorification".

Le Monde published an editorial after the latest attack, the murder of an elderly priest in a church near Rouen by two men claiming allegiance to Islamic State. Under the headline "Resisting the strategy of hate", Le Monde argued on Wednesday that all elements of society had to be involved in the struggle against terrorism, and that media organisations had a special role to play.

"The sites and newspapers that produce this information cannot excuse themselves from self-examination on several fronts. Since Isis terrorism first appeared, Le Monde has changed its practices several times," the newspaper said.

It first chose not to republish images from Isis propaganda documents. Then, after the attack in Nice on 14 July, when a truck drove through crowds enjoying the Bastille Day public holiday, Le Monde said it had decided to "no longer publish photographs of the perpetrators of killings, to avoid the potential effect of posthumous glorification".
