It’s at the VERY END of the vid..
Almost like there were two attempts in the works. One team and one lone bomber , unaware of the others. Looks like the shooter is grabbed by the shoulders and turned back and too his left and pushed away by someone dressed almost in the same manner......yet they have no time too get away before the bomb goes off.
How many others were killed in that blast ? If that guy that was the trigger was thrown too the ground or into a crowd away from the bomb he could still be walking around .....albeit saying Huh ? A lot.
Good eye RR.......
