Two Islamic State leaders behind the terrorist attacks in Paris last year were killed in a U.S.-led drone strike Dec. 4 in Raqqa, Syria, the Pentagon confirmed Tuesday.

The two targets, Salah Gourmat and Sammy Djedou, worked with external terror operations and recruitment of foreign fighters in Europe. They were directly involved in facilitating the Nov. 13 attacks in Paris, which killed 130 people.

Gourmat and Djedou were close associates of Abu Muhammad al-Adnani, ISIS's former chief spokesman who was killed in a U.S. drone strike in August. (RELATED: ISIS Leader Sees Sunshine For First Time In Months, Hellfire Missile Obliterates Him)
