Police sources said unidentified miscreants opened fire on the polio team in the Shalkot area, killing a mother-daughter duo in what law enforcers believe is a targeted attack.
The assailants escaped unhurt from the site of the attack, police said, as a heavy contingent of law enforcers and Frontier Corps reached the area.
This is the second incident of violence in Quetta today. Earlier today, two policemen were shot dead in a targeted attack in the Zarghoon Road area.
