KARACHI, Pakistan (AP) -- Police say four more bodies have been found in Pakistan's largest city, bringing the death toll in three days of suspected gang-related violence to 52.
Many of the victims in Karachi were tortured, shot and stuffed in sacks dumped on streets.
Police chief Saud Mirza says the new bodies were discovered Friday morning. Seventeen people were killed Wednesday, and 31 on Thursday.
The gangs are allegedly affiliated with the city's main political parties and have been blamed for a surge in killings in recent months in Karachi, a city of some 18 million people.
Although Karachi has a long history of political, ethnic and sectarian violence, the recent wave is high by historical standards. More than 300 people were killed in July alone.
