The day before, the new issue, with a cartoon of the Prophet Muhammad on its cover, appeared on the stands.
Investigations editor Laurent Leger told BBC News:
"I don't have any regrets, I'm proud of this publication. We discussed the possibility of a big debate, because debating is normal, it's logical in a democracy. I mean you can talk and talk and write but not bombings, not to put a bomb in our offices. That's not normal, it's criminal... Not against the offices but against freedom of thinking, of writing and publishing."
