KARACHI: At least 12 people including a Shia doctor and three madressa students were killed and several others injured in different incidents of violence in the port city, DawnNews reported on Wednesday.

The latest incident took place near Continental Bakery in Gulistan-i-Jauhar neighbourhood when unidentified attackers killed three students of an Islamic seminary. Two students sustained bullets wounds also. They are reportedly in critical condition at Jinnah Postgraduate Medical Centre (JPMC).

Enraged people took to the streets after the incident. They set ablaze push carts and forced local shop keepers to shut their businesses.

Police and Rangers personnel reached the site to disperse the angry mob.

The incident followed yet another high-profile Shia killing in the same area when Doctor Haider Raza was gunned down by unidentified attackers in front of Darul Sehat Hospital. Another man accompanying Raza in his car was injured in the attack. His identity is yet not known.

Jafaria Alliance and Pakistan Shia Ulema Council condemning the attack demanded an early arrest of the culprits.

Earlier during the day, a bomb weighing 13 kilograms was defused near Khalid Bin Waleed road in Karachi’s PECHS area.

Karachi, the largest metropolitan city of Pakistan, is riddled with targeted killings, gang wars, kidnappings for ransom, extortion and sectarian violence. Targeted operations led by Rangers’ forces with the support of police are ongoing in the city under a directive issued by the federal government against criminals already identified by federal, military and civilian agencies.
