KARACHI: At least 12 people were killed in renewed unrest in Karachi during the past 24 hours, DawnNews reported.

Moreover, Inspector General Sindh Wajid Ali Khan Durrani said terrorists were better armed in Karachi than the police.

On Tuesday, parts of the city descended into violence and those killed included two political activists. The activities were gunned down and some private property was also damaged in arson attacks.

The fresh killings and subsequent arson attacks mainly in Orangi were carried out at a time when the new police set-up started functioning in the city following the Monday notification of the new police officers of the five districts.
