Karachi January 12, 2021 A little more than half a kilometre of the bank of Karachiâs Mehmoodabad Nullah was rid of hard encroachments as the second phase of the operation for clearing both sides of the storm water drain started on Monday. Six or seven houses were partially demolished, while the rest of the residents of the locality were told to vacate their homes in two or three days. Last weekâs four-day operation of the Karachi Metropolitan Corporation (KMC) saw the land on either side of the nullah cleared of all kinds of soft encroachments in the presence of a heavy contingent of police and other law enforcers.
