Killing Innocent in Karachi : Responsile is Who??

Just in a Week in the City of Lights-Karachi, around 40 people have been shooted by Un-Know shooters, who just fired a bullet and ran away.
The killed belonged to the Different Plitical parties lies MQM, ANP, Jamat-e-Islami, PML(N), PPP and the Tehrik Sunnat.
and the Political icons like Zulfikar Mirza from the Sindh Government says " hum to kya Amerca ki police bhi Karachi men Target Killing ko nahn roksakti" :))

In my thought the Reason behind the target killing is , No Law and Order Bieng Obeserved.

Bomb Bomb

Very Bad Scene on Ashura.
Many Killed in bomb Blost, and the Bussiness near By looted and burnt by target Killers in karachi at Boleten Market.
