At least four people were killed and 19 injured in an explosion in Quetta on Saturday, Civil Hospital Spokesperson Waseem Baig said.

A Frontier Corps (FC) vehicle was the target of blast, Balochistan Home Minister Sarfaraz Bugti confirmed. Two FC vehicles, three rickshaws and motorcycles were also damaged as result of the blast.

Deputy Inspector General (DIG) Police Quetta Abdul Razzaq Cheema said most of the victims were civilians and that a child was among the dead.

He said the blast seemed to have been the result of a suicide attack.

The injured have been shifted to Civil Hospital Quetta, while those critically injured have been moved to the Trauma Centre.

The intensity of the blast rocked the entire Sariab Road area, prompting shopkeepers in the area to pull down their shutters. Traffic was also suspended.

Police and personnel of FC cordoned off the attack site as an investigation into the blast went underway.

Sariab Road is considered to be one of the more sensitive areas of Quetta. Miscreants in the area have targeted security forces, police and officials for more than a decade.
