Gunmen have attacked the Paris office of French satirical magazine Charlie Hebdo, killing 12 people and injuring seven in an apparent Islamist attack, reports the BBC.

At least two masked attackers opened fire with assault rifles in the office and exchanged shots with police in the street outside before escaping by car.

The gunmen shouted "we have avenged the Prophet Muhammad", witnesses say.
