On 7 January 2015 at about 11:30 a.m. CET local time, two French Muslim brothers, Saïd and Chérif Kouachi, forced their way into the offices of the French satirical weekly newspaper
Charlie Hebdo in Paris. Armed with rifles and other weapons, they killed 12 people and injured 11 others. The gunmen identified themselves as belonging to the Islamic terrorist group al-Qaeda in the Arabian Peninsula, which took responsibility for the attack. Several related attacks followed in the Île-de-France region on 7–9 January 2015, including the Hypercacher kosher supermarket siege where a terrorist held 19 hostages, of whom he murdered four Jewish people.
