Boubaker el Hakim, an ISIS leader believed to have played a role in the ISIS attack on Charlie Hebdo, was killed in Raqqa, Syria in late November.

Intelligence failures, in France and abroad, led to the failure to foil attacks in Paris last year by Islamic radicals that killed 147 people.

In a special edition laced with blasphemy, obscenity and profanity, Charlie Hebdo's surviving artists and writers declared that the satirical newspaper is alive, but "the murderer is still at large."
