Sir: Karachi University (KU), which is the second largest university in Pakistan and is known for producing acclaimed scholars, has become a hub of criminal activities. Political parties use students to unleash personal vendettas. Political activities on the university premises are causing distress among students. Even the heavy contingents of Rangers deployed in the university are unable to check these negative activities. Innocent lives are lost due to clashes among rival parties. Who is to be blamed for this situation? A country where academic institutions are not safe and are turned into battlegrounds, where else could one look for peace and harmony?SAIMA YASEENKarachi
