On 7 January 2015, two men 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 terrorist group al-Qaeda on 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 4 Jewish people.
