François Vauglin, the mayor of the 11th arrondissement, told BFM TV that he had asked the schools and nurseries in the neighborhood to lock themselves out as a precaution.
While in recent years, numerous attacks in France have targeted law enforcement officers, especially in 2017 when a veteran police officer was shot dead on the Champs-Élysées, the attackers also orchestrated indiscriminate attacks.
In March 2018, an armed man killed four people in a supermarket in southern France, including a police officer, and two months later, an assailant stabbed five people near the Paris Opera, including one fatally. In October 2019, a former police employee killed four of his colleagues in a knife attack at Paris police headquarters, in what authorities later called a terrorist attack.
Al-Qaeda, the terrorist group, had recently launched new threats against Charlie Hebdo, which moved after the 2015 attack to highly secure offices elsewhere. The threats followed the newspaper’s decision to reprint satirical cartoons of the Prophet Muhammad at the start of the trial of several people accused of aiding the attackers.
During the 2015 attack, two brothers, Chérif and Saïd Kouachi, broke into the building housing the satirical newspaper and shot and killed a maintenance worker. The brothers then forced under the threat of a cartoonist, who had just come out, to enter a security code to access the offices.
