At least 12 people were killed and five seriously injured after masked men stormed the offices of Paris-based satirical magazine Charlie Hebdo at around midday on Wednesday.
The incident is France's deadliest terror attack in at least two decades.
French president François Hollande said the shooting was "undoubtedly" a terrorist attack.
It is thought one motivation for the attack may have been some of the controversial cartoons the magazine has published, including some caricatures of the Prophet Muhammed.
However, no group has yet come forward to claim responsibility for the attack and the gunmen remain at large.
Twitter users shared several of these moving cartoons as a tribute to the victims of the killings.

The cartoon for French daily Le Monde read "all hearts with Charlie Hebdo".
The newspaper wrote: "Le Monde expresses its amazement and indignation, solidarity with the team of Charlie Hebdo and condolences to the victims' families.
"Attacking our colleague is an attack on freedom of thought and expression, and thus the founding values ??of our society.?Le Monde has continued since these values since its creation in 1944."

Separately the hashtag #JeSuisCharlie (which means "I am Charlie" in French) began trending worldwide on Twitter around an hour after the news of the shootings broke.
British satirical publication the Daily Mash changed its Twitter profile picture to 'Je Suis Charlie', while German newspaper Bild were among hundreds of thousands who tweeted out the image and the hashtag. The US embassy in France also changed its Twitter profile picture to "Je Suis Charlie".

More than 100,000 people gathered across France to pay tribute to the victims of Wednesday's massacre by Islamist gunmen in Paris, as thousands also rallied in other European cities and the "JeSuisCharlie" hashtag swept the Internet.
As at 1pm New Zealand time there had been over 2.1 million tweets using #JeSuisCharlie.
With the gunmen still on the loose in Paris after killing 12 people, defiant crowds swarmed into the Place de la Republique, barely a kilometre (half a mile) from the scene of the bloodbath at the Charlie Hebdo satirical weekly.
At least 35,000 held vigils in Paris, and some 20,000 people turned out in the French cities of Lyon and Toulouse, police said. Thousands more took to the streets in cities including Bordeaux and Marseille.
There were also rallies in European cities such as Berlin, London and Lausanne. Many demonstrators wore black stickers with the words "Je suis Charlie" (I am Charlie), a slogan aimed at showing solidarity with the victims of the deadliest attack in France in decades and in support of the paper's decision to print controversial prophet Mohammed cartoons.

Others waved banners with slogans such as "Press freedom has no price" and "Charb mort libre" (Charb died free), a reference to the newspaper's slain editor-in-chief Stephane Charbonnier. Charbonnier was one of four cartoonists killed in the attack that also left 11 people injured.
The provocative magazine had repeatedly published controversial cartoons of the prophet Mohammed, in part as a campaign to defend freedom of the press, but offending many Muslims who view such depictions as blasphemous.
"It's terrible that these people were murdered. In future, no one will be able to speak his mind. We have to demonstrate in our thousands," said Beatrice Cano, a woman in her fifties carrying the latest issue of Charlie Hebdo in Paris.
Others carried candles or even pencils as a symbol of support for freedom of the press. The "Je suis Charlie" slogan and hashtag spread quickly on the Internet, with Charlie Hebdo itself replacing its homepage with the phrase printed on a black background.
Clicking on a link revealed translations of the phrase into a number of languages, including Arabic.
Mourners take to social media
Many replaced their social media profile pictures with the slogan, including the US embassy in France for a time.
The hashtag #jesuischarlie was used hundreds of thousands of times on Twitter.
Others reposted old cartoons from Charlie Hebdo, including one showing a jihadist set to decapitate Mohammed.
Media outlets globally tweeted tributes, including a drawing of the four cartoonists and a quote from Charbonnier: "I prefer to die standing than live on my knees.
"Photos showing protesters holding a sign reading "Not Afraid" were also widely shared online while the slogan "the pen is mightier than the sword" was repeatedly tweeted.
French resident Yannick Raynaud summed up the sentiment in France with a tweet that said: "They wanted 2 bring France 2 her knees, instead they made her stand up" #JeSuisCharlie Amazing picParis! #standproud
