Cartoonists worldwide respond to Charlie Hebdo killings

MANILA, PHILIPPINES – "Cartoonists & Writers everywhere. Keep your wits sharp & your pencils sharper. "

On Wednesday, January 7, 12 people at the office of the French satirical newspaper Charlie Hebdo were killed in an attack by at least two masked men who screamed "Allahu akbar" as they shot the victims.

French President Francois Hollande declared a day of national mourning on Thursday, January 8, and more than 100,000 gathered across France, many protesters carrying banners reading "I am Charlie." The hashtag #JeSuisCharlie (French for "I am Charlie") also trended worldwide, including versions in Arabic.

Cartoonists around the world have taken to social media as well to show that the only thing these gruesome attacks proves is that the pen is mightier than the sword.
