That's a LIE! Press footage suggests otherwise. A peaceful procession is proceeding on its way, some mullah turns on the loud speaker of the masjid, starts instigating like minded folks to stop these "kafirs" in there foots - - - - - - - - - miscreants then take control of the masjid roof and a barrage of bricks and stones is dispatched towards the procession - - - -.
Some shia youth gets agitated, elders try to cool em down but are pushed back - - - all on footage.. Before this episode took place, there had been many suicide bombings on Shias in Rawalpindi----.
What followed was also horrible, a professor of gujrat University gets assassinated and another shia killing spree kicks into action.
P.S : No beheadings took place, no heads got dipped into honey to be preserved as trophies, no water and food supply got blocked, no corpses were set on fire, none ripped off the pregnant ladies bellies and threw their infants off the cliffs - - - - - only weapons used were fists, kicks and sadly ak 47's.
