France's anti-terrorism prosecutor has taken picture magazine Paris Match to court in an urgent effort to stop sales of its latest edition showing gruesome photos of the terror attack in Nice.
The prosecutor's office said a hearing was set for later on Thursday to get the publication withdrawn from news stands.
Victims' organisations denounced the photos as the Riviera city of Nice prepares for the Bastille Day celebrations and the commemoration of the 86 people killed on July 14 2016, when a 19-ton truck barrelled into celebrating crowds.
Stephan Gicquel, who heads the leading victims' association Fenvac, said on BFM-TV that a favourable ruling would be a "strong signal to show... there are limits".
He added that "we don't need these shock pictures to understand the horror of terrorism".
The magazine's executive director Olivier Royant said he would defend "tooth and nail" what he said was "the right of citizens, first among them the victims, to know exactly what happened" on the day of the fatal attack.
He said the report, with photos, was a way for his publication "to pay homage to victims... so that society does not forget", adding that the right of the media to inform is a foundation of democracy.
