Mass murder and target killings in Karachi are intolerable. The daily routine of smattering streets of Karachi with blood of the 'aborigines of the city is going on and on. A well-known terrorist group is slaying more and more innocent people, even those that are settled in Karachi for centuries by calling them aliens. This so-called political group having ethnic orientation is an ally of the international imperialism that is working in this city with the aim to grab all resources of this part of the world. -DR MOHAMMAD MATARO HINGORJO, Jamshoro, January 11.
