Kurdish-led forces gave the United States key DNA evidence, including ISIS leader Abu Bakr al-Baghdadi’s used underwear and blood, before the raid that killed him on Saturday, the leader of Kurdish forces said in an interview with NBC News.
Syrian Democratic Forces Gen. Mazloum Abdi described the source as one of Baghdadi’s security advisers, who proved to U.S. intelligence that he had direct access to Baghdadi by handing over his used underwear and a sample of his blood.
U.S. intelligence tested the samples and got positive DNA matches for Baghdadi this summer, according to Abdi. He did not describe how the informant obtained the blood. He said that the informant was able to describe a room-by-room layout of Baghdadi’s compound, including the number of guards, floor plans, and tunnels.
