Hypercacher kosher supermarket siege
On 9 January 2015, Amedy Coulibaly, armed with a submachine gun, an assault rifle, and two Tokarev pistols, entered and attacked a Hypercacher kosher supermarket in Porte de Vincennes in Paris, France. There, Coulibaly murdered four Jewish hostages and held fifteen other hostages during a siege in which he demanded that the perpetrators of the Charlie Hebdo shooting, the Kouachi brothers, not be harmed.
