French police say at least 11 people are dead after a shooting at the Paris headquarters of the satirical weekly paper Charlie Hebdo.
Media reports say at least two gunmen opened fire with Kalashnikov rifles and a rocket launcher inside the building housing the newspaper's offices. After the shooting, the gunmen are believed to have fled in two different vehicles.
French President Francois Hollande told reporters that the incident was "no doubt" a terrorist attack. He was headed to the scene of the shooting.
France has raised its terror alert in Paris to the highest level following the attack.
In 2011, the satirical newspaper's office was fire-bombed after it published an issue featuring a cartoon image of the Prophet Muhammed on its cover.
