ISIS has reportedly claimed credit for the attacks separately in a statement it released in Arabic and French. Another statement claimed to be from ISIS reads: "Our brothers who carried out these miracles in Gaul, the day of 29th and 30th Muharram."
The dates mentioned are related to the Islamic calendar and correspond to Nov. 12 and Nov. 13, respectively. The statement is being credited to the official media wing of ISIS, known as the Al-Hayat Media Center, which warns: "Today we bring you your death, and tomorrow we will do the same."
