Pakistan bomb: Karachi standstill after Shias attacked

A powerful bomb ripped in Karachi. The bomb killig 45 people or more. After these strike , schools and bussiness was called to protest these attac. Nobody says who put the bomb in this place but Pakistan's Shia minority are a group that always attac by sunni militans. The explosion destroyed buildings and there are 150 wounded.

In my opinon the terrorist attacs in this countries are very terriyfing, because there are a lot of inocent people that the terrorist kill and the buildings support big attacs. In this cases police doesn't do anithing but I think that they would do more but they don't like anithing.
