Authorities have confirmed that the attack on a Parisian magazine's publication office has left twelve dead. The massacre is believed to be a terrorist attack carried out by militant Islamists.

Of the twelve deaths, four were of the magazine's popular cartoonists, one of them also being the editor.

The Charlie Hebdo attack is being considered the most fatal attack on France since 1961, when a bomb set off by radicals supporting French Algeria killed twenty-eight people on a train. This time, the terrorists wearing masks entered an office in the Charlie Hebdo building during an editorial meeting, read off the names of their targets, and shot them with rifles before firing shots at police in the street. The attackers then fled away by car, and proceeded to leave the vehicle behind in northern Paris to hijack another car.

Those who witnessed the massacre claim they could hear the suspects shouting Islamic threats in Arabic, such as "We have avenged the Prophet Muhammad" and "God is great."

On that note, it has been revealed the the editor of Charlie Hebdo had been receiving death threats and was living under the protection of police. In addition to the twelve deaths during the attack, four other magazine employees were injured in the terrorist assault.
