Parts of Karachi remained tense on Saturday as the death toll in the latest round of violence reached 20.

Thirteen people were killed in Karachi on Friday as the Muhajir Qaumi Movement, better known as Haqiqi, attempted to stage a comeback in strongholds of the Muttahida Qaumi Movement (MQM).

City police chief Saud Mirza on Friday said the violence was sparked when “some men of a group entered Khokhrapar area of Malir and targeted their opponents”.

The area remained under siege for over three hours and gunmen were seen strutting about without facing any resistance from police and Rangers.

The violence led President Zardari to summon Sindh Home Minister Manzoor Hussain Wasan to discuss the situation.

The meeting between the two, which lasted almost an hour, ended with a resolve to meet the challenge and take indiscriminate action against terrorists.

“It would not be justified to blame anyone for recent violence as I don’t believe in politics of blame game,” the minister said after the meeting on Friday.
