For 4th Time, Nigerian Military Claims It Killed Boko Haram Leader Claims have not been independently verified By Evann Gastaldo, Newser Staff Posted Aug 24, 2016 12:00 AM CDT 4 comments Comments This Monday May 12, 2014, file photo taken from video by Nigeria's Boko Haram terrorist network shows their leader Abubakar Shekau speaking to the camera. (AP Photo/File) (Newser) – For the fourth time, Nigeria's military says Abubakar Shekau, the leader of militant group Boko Haram, has been killed. On all three prior occasions, Shekau (or at least, someone claiming to be him) has afterward shown up again in new videos. The Wall Street Journal notes that the most recent claims of his demise cannot be independently verified. The Nigerian military said Tuesday that Shekau and other top Boko Haram commanders were killed in an "unprecedented and spectacular air raid" Friday. Boko Haram did not immediately respond to the military's claims.
