Masked gunmen wielding Kalashnikovs and a rocket launcher killed at least 12 people and injured 10 more at the Paris offices of satirical French newspaper Charlie Hebdo on Wednesday before escaping. French president François Hollande called the shooting "unquestionably a terrorist attack."

Video published by BFMTV and Le Monde, said to be from outside the Charlie Hebdo offices, shows two masked gunmen with large rifles.
