Video thanks to Golem, who writes: "Shia Muslims have been viciously persecuted in Pakistan for decades...[1] Here is a recent article describing this situation." Note that it is from an Iranian Shi'ite source; still, it gives much illuminating information.

Golem adds about the video above: "Here is a brutal example of this situation, a Shia Muslim who survived a prior attack, being gunned down in the hospital."
