dude I hate the MQM, but your conspiracy theories are just dumb, i don't think you even live here in Karachi; this was clearly an attack by the Taliban or other fanatics; MQM has a lot of Ismailis, they get the Ismaili vote eveytime in Karachi.
I think people living in Punjab need to learn a little about Karachi demographics, the safoora goth area is dominated by Afghan refugees, non-Afghans don't go there that much.
So it makes more sense to evict Afghans from KHI and clean up the Afghan ghettoes
