Initially, reports indicated that an airstrike in the northeastern Syrian town of Shaddadi likely succeeded in "eliminating" the militant. But "on-the-ground" intelligence from London-based Syrian Observatory for Human Rights (who else?) suggested that in fact, al-Shishani was still alive and had been transported to Raqqa where he was being treated for serious injuries.

Fast forward to Monday and we find out that even if al-Shishani isn't technically dead, he is now "clinically dead," which according to Rami Abdel Rahman (who runs the one-man Observatory for Human Rights) means "Shishani is not able to breathe on his own and is using machines."

"He has been clinically dead for several days," Rami adds.

When the US announced the strike last Tuesday, officials likened Shishani to "the ISIS equivalent of the secretary of defense," although we have to say, he doesn't look much like Ash Carter.
