France's interior minister is protesting accusations the government tried to cover up security failings the night of the Bastille Day attack in Nice that killed 84 people.
Sandra Bertin, the woman in charge of video surveillance in Nice on July 14, told the Journal du Dimanche newspaper that government officials told her what to write in her report and that she should mention the presence of police she had not seen.
Interior Minister Bernard Cazeneuve said in a statement on Sunday that he is suing for alleged defamation and is committed to uncovering the truth about what happened.
Many French people are angry that the government could not prevent the Nice attack despite a state of emergency being in place.
Mr Cazeneuve acknowledged that no national police were protecting the beachfront promenade targeted in the attack.
