PARIS: Hooded gunmen stormed the Paris offices of a weekly satirical magazine, killing at least 12 people, including two police officers in the worst militant attack on French soil in recent decades.

Charlie Hebdo (Charlie Weekly) is well known for courting controversy with satirical attacks on political and religious leaders.

Two assailants were captured on video calmly leaving the scene after the shooting. A police union official said the assailants remained at liberty and there were fears of further attacks.

The satirical newspaper has been firebombed in the past after publishing cartoons joking about Muslim leaders.

France Info radio said police had confirmed 10 injured. Police informed Reuters that of the 10 wounded, five were injured critically. The news channel quoted a witness as saying he saw the incident from a building nearby in the heart of the French capital.
