Two unidentified attackers stormed the Paris offices of controversial satirical newspaper Charlie Hebdo Wednesday, killing at least 11 people and injuring 10 others, according to local authorities.
A witness told French media the two attackers were armed with Kalashnikovs when they invaded the building in downtown Paris.
Five of the injured are in a serious condition, according to a statement from the Paris police prefecture.
Among the dead is one journalist, according to police official Luc Poignant.
“It's carnage,” Poignant told BFM TV.
The reason behind the attack remains unknown.
Charlie Hebdo has drawn international controversy for its repeated publication of cartoons depicting the Prophet Muhammad. In 2011 the newspaper's offices were firebombed after publishing a caricature of Muhammad on the cover of an issue.
According to an anonymous government source cited by Reuters, French President Francois Hollande will head to the scene of the shooting shortly to hold an emergency meeting.
