The problem of transport in Karachi University is nothing new but it has become rather more severe in the month of Ramadan. KU has closed the shuttle service on the premises of university because of a recent clash between students that resulted in four casualties. At the moment, thousands of students (who are not responsible for this clash) have to walk from main gate to their departments. What kind of punishment is this? -JAWAID IMAM, Karachi, via e-mail, September 12.
