Actually it's war of monopoly in Karachi. There are, according to an estimate, more than 6 million Pakhtun if they registered their votes, MQM will lose its hegemony. Participants mentioned by Hafiz Shab are correct but most frequently clash occurs between MQM and ANP.

All of the police officials who participated in Karachi Operation, are killed one by one and according to the story which I read in DAWN, plan was devised in Governor House Karachi. So, it is not easy to detain the culprits easily.

Govt.'s silence is due to the influence of MQM and Govt. don't want any disturbance so, they bypass such heinous murders. Most of the people who die are Pakhtuns. It's totally ethnic issue and it can only be solved when MQM will accept the status of Pakhtuns in Karachi and leave regional politics and join politics of national level.
