The head of the Human Resources department at Charlie Hebdo magazine has been forced to leave her home and live in hiding because of "precise and detailed threats" to her security guards, reports BBC News.
Marika Bret said her guards, who have protected her for almost five years, received the threats on September 14th.
She blamed "an unreal level of hatred around Charlie Hebdo".
The magazine was the target of a deadly terror attack in January 2015, in which 12 people were killed, after publishing cartoons of the Prophet Mohammed.
The attacks began a wave of jihadist strikes across France.
Earlier this month the magazine republished the controversial cartoons, ahead of 14 people going on trial accused of assisting the two gunmen in that attack.
Speaking to Le Point magazine, Ms Bret said: "I had ten minutes to do my business and leave my home, ten minutes to give up part of my existence... I won't be coming home."
She added that the threats started again with the start of the trial and the republication of the cartoons of Prophet Mohammed earlier this month.
"Since the start of the trial and with the republication of the cartoons, we have received all kinds of horrors, including threats from al-Qaeda and calls to finish the work of the [gunmen from the 2015 attack]," she said.
The front cover of the issue of Charlie Hebdo published at the start of September featured the 12 original cartoons of the Prophet Mohammed, which were published in a Danish newspaper before appearing in Charlie Hebdo.
