QUETTA: Three people were killed and two sustained injuries on Tuesday when unidentified gunmen attacked a yellow cab at Quetta’s Spiny Road, DawnNews reported.

According to police sources, the unidentified motorcycle riders opened fire at the cab, which was carrying five people to a town in Hazara district, injuring all passengers.

Three of five injured succumbed to their wounds while being taken to the Bolan Medical Complex.

The attackers escaped the site immediately after the incident, said a police official.

A heavy contingent of police and Frontier Constabulary (FC) cordoned off the area and initiated an investigation.

The incident forced many shop owners to shut their shops and small business in the area. Many enraged residents also came out on roads to protest against the attack and shouted slogans against the government. They set blaze tyres in front of the hospital as well.

The police have declared that the attack was an incident of targeted killing.

The victims are yet to be identified but Balochistan is rife with sectarian violence, where several people, particularly Shia Hazaras have been targeted in the recent past.
