This much is certain: Charlie Hebdo will live another day.

The magazine, which was the target of a deadly attack Wednesday, will be kept going through financial and editorial backing from some of France's largest media groups.

Luc Bronner, a top editor at Le Monde, a leading French newspaper, tweeted a joint letter from Groupe Le Monde, which owns Le Monde, as well as public broadcasters Radio France and France Televisions.

The letter says the three media organizations are offering Charlie Hebdo their equipment and staff to ensure the magazine continues to publish. It also invites other French media organization to join the effort to "preserve the principles of editorial independence and freedom of thought — principles that are fundamental to our democracy."

Although there have been expressions of solidarity for the weekly satirical magazine across France, the letter is so far the most direct offer of support.

Journalists across France observed a minute of silence and held placards that said "Je Suis Charlie." (I Am Charlie.) Here's an image from the Agence France-Presse newsroom.

There also have been massive rallies in Paris, where the gunmen who carried out the attack are still at large, to express solidarity with Charlie Hebdo.
