Hundreds of supporters of Pakistan Tehreek-e-Insaf (PTI) staged a sit-in in Karachi on Saturday, suspending traffic on Shara-e-Faisal. The sit-in began on the city's most busy thoroughfare despite refusal of police officials to grant the permission. Both the tracks of Shara-e-Faisal have been blocked by participants in the sit-in. On Friday, PTI Chairman Imran Khan announced that his party would launch sit-ins in Karachi, Multan, Faisalabad and Lahore.
