Facebook boss Mark Zuckerberg has used his own social networking page to condemn this week's attack on the staff of French satirical publication Charlie Hebdo.
Three gunmen, thought to be Islamist extremists, opened fire at the Charlie Hebdo offices in Paris, believed to be acting in retaliation to cartoons published depicting the prophet Muhammed. 12 people were killed, including two police officers. The gunmen remain on the run.
Now Zuckerberg has come out to show his support for those murdered, and reaffirm his goal to allow Facebook to be a digital destination where users can speak freely "without fear of violence".
A few years ago, an extremist in Pakistan fought to have me sentenced to death because Facebook refused to ban content about Mohammed that offended him.
We stood up for this because different voices -- even if they're sometimes offensive -- can make the world a better and more interesting place.
Facebook has always been a place where people across the world share their views and ideas. We follow the laws in each country, but we never let one country or group of people dictate what people can share across the world.
Yet as I reflect on yesterday's attack and my own experience with extremism, this is what we all need to reject -- a group of extremists trying to silence the voices and opinions of everyone else around the world.
I won't let that happen on Facebook. I'm committed to building a service where you can speak freely without fear of violence.
My thoughts are with the victims, their families, the people of France and the people all over the world who choose to share their views and ideas, even when that takes courage. #JeSuisCharlie
