On Jan. 7, 2015, the French satirical magazine Charlie Hebdo was targeted by two Islamic extremists over a cartoon drawing of the Prophet Muhammad, which the magazine had published in 2006.

The two brothers who carried out the shooting injured 11 and killed 12 others, including nine members of Charlie Hebdo’s editorial team, a guard, a patrol officer, and one guest. The killers, who were supporters of the terrorist group al Qaeda, fled the scene and a manhunt broke out while authorities searched for the two brothers, Cherif and Said Kouachi.
