Karachi ground to a halt Tuesday, with most residents staying off the streets after MQM called a day of mourning to protest the deaths of at least 96 people killed in Karachi in the past week. Businesses, schools and government offices were closed, while public buses and taxis stayed off the road. The strike, called by Muttahida Qaumi Movement, came as police found the bodies of 10 more people.

The government has been unable to stop the fighting, as it also grapples with a faltering economy and a raging Islamist insurgency. "We condemn the killing of all innocent citizens, but the present wave of killing is part of a genocide of Urdu-speaking people,' Sattar said during a press conference on Monday.
