Sometimes you can convey an idea better with images than words.
That's undoubtedly the case when it comes to the deadly mass shooting at the offices of Charlie Hebdo, a satirical publication in Paris.
Massive crowds gathered across Europe, holding up pens in a show of solidarity with the newspaper's journalists.
And on social media, artists are using their own pens to send a message.
Here are some of the most powerful artistic images that emerged in the wake of the shootings:
Translation: "Ink must flow. Not blood."
Translation: "The world has become so serious that humour has become a risky profession."
Translation: "Today, I'm a cartoonist. Today, I'm a journalist. Today, I draw for Charlie Hebdo."
Translation: "Not a fair fight."
Translation: "Wholeheartedly with Charlie Hebdo."
Translation: "Take up arms, companions!"
Translation: "Oh no, not them ..."
