As many as 33 people lost their lives and 50 were injured in incidents of violence in different parts of the city in 30 hours till Sunday midnight.
Five vehicles, including a car belonging to the DawnNews, were set ablaze at Safoora Chowk on late Saturday night. City Police Chief Fayyaz Ahmed Leghari said around 30 people had fallen victims to targeted killings.
In reply to a question about ethnic profiles of the victims, the CCPO said they belonged to different groups.
The fresh spate of killings coincided with by-elections for the PS-94, Orangi Town, which fell vacant after the assassination of MQM MPA Raza Haider.
According to unofficial results, MQM’s candidate Saifuddin Khalid won the seat comfortably.
The Awami National Party announced on Saturday that it was boycotting the election because its demand to deploy troops had not been met.
The toll has risen to 37, according to latest reports.
