On 7 January 2015 at about 11:30 local time, two brothers, Saïd and Chérif Kouachi, forced their way into the offices of the French satirical weekly newspaper Charlie Hebdo in Paris. Armed with assault rifles and other weapons, they killed 11 people and injured 11 others in the building. After leaving, they killed a French National Police officer outside the building. The gunmen identified themselves as belonging to the Islamist terrorist group Al-Qaeda's branch in Yemen, who took responsibility for the attack. Several related attacks followed in the Île-de-France region, where a further five were killed and 11 wounded.
