Three levies forces personnel were martyred in a targeted attack on Quetta's Sariab Road on Eid day, DawnNewsTV reported.
Initial reports suggest that a paramilitary forces vehicle was intercepted by unidentified men on Sariab Road near Killi Bangulzai.
The levies personnel sitting in the car were fired at by the attackers. They lost their lives after suffering bullet injuries.
Rescue teams later reached the scene and moved the slain personnel's bodies to Civil Hospital Quetta.
The slain men have been identified as Anwar Ali and the brothers Najeebullah and Haseebullah.
Quetta's Deputy Inspector General of Police Razzaq Cheema said the miscreants had escaped unhurt from the spot after the attack.
"This seems to be an act of targeted killing," he said.
Cheema had earlier said over 4,000 police and Frontier Corps personnel had been deployed on the eve of Eid in Quetta city.
