it is really shameful for pakistani police to admit this type of situation. If they knew what is happening then why they dont act instead of wait till next blast.
What Pakistani Police has to do with it? They found this after investigation.
Parts of pakistan have become a cesspool for this type of activity, and we still have people finding ways to justify suicide bombers by offering excuses or deflecting blame.
Allah hi aqal ataa farmaye un ko, Ameen !
