Eleven people were killed Wednesday when masked gunmen opened fire after storming the office of a French satirical magazine that courted controversy over its portrayal of Prophet Mohammed.
BBC and Sky News quoted witnesses as saying that a number of hooded men were involved in the horrific attack on the office of Charlie Hebdo which also left 10 others badly wounded.
Police confirmed 11 deaths and said they have launched a manhunt for the killers.
A journalist told iTele network that he saw several masked armed men. They reportedly fired from automatic rifles.
A broadcast journalist with Europe1 News said the attackers were heard shouting "the Prophet has been avenged" before they fled.
The London-based Telegraph quoted a man as saying that the attackers escaped in two vehicles.
Charlie's latest tweet -- just about an hour before the attack -- was a cartoon of the IS militant leader Abu Bakr al-Baghdadi.
The magazine was fire-bombed in November 2011, a day after it carried a caricature of Prophet Mohammed.
