People Are Rallying In Support Of Charlie Hebdo Across Europe

Marches and other displays of solidarity are popping up across France and Europe in the wake of the deadly attack on the offices of satirical weekly magazine Charlie Hebdo.

Many of them are being captured on social media under the hashtag #JeSuisCharlie. On the afternoon of Jan. 7, the words appeared on Twitter over 21,000 times in just an hour.

In the French capital, Parisians held up pens in a show of support for freedom of expression.

The white-on-black "Je Suis Charlie" sign also appeared in Berlin, as captured by an AFP photographer. A crowd gathered around the German capital's French embassy.

The AFP's own newsroom passed copies of the motto around for a solidarity photo (the American embassy in Paris also changed its Twitter profile image to present the words).

And Le Monde used the image of a crowd carrying the words "Not Afraid" as the banner for its main web story covering the attack.
