Next edition of Charlie Hebdo to appear Feb. 25: journalist

"Finally. A bit more patience, but Charlie Hebdo will come out on February 25 at all good kiosks," said Laurent Leger on his Twitter account.

A so-called "survivors' issue" published on January 14 had a print run of seven million, with a first batch selling out within minutes. Before the attacks, the weekly sold around 30,000 copies.

The front cover of the last issue featured a cartoon of the prophet Mohammed holding a sign "Je Suis Charlie", which became a rallying cry for freedom of expression since the deadly attacks, and the words "all is forgiven" over the cartoon.

The cover sparked deadly demonstrations in some parts of the Muslim world, where depicting the prophet is seen as deeply offensive.

The new publishing director of the magazine said last month that there would "probably not" be a cartoon of the prophet in the next edition.

On January 7, two Islamist gunmen stormed into Charlie Hebdo's offices in Paris and killed 12 people, most of them journalists and cartoonists.
