The gunmen opened fire on the polio team in the Shalkot area, killing the two women in what law enforcers believe is a targeted attack, Dawn reported, quoting police sources.
The attackers escaped unhurt from the site of the attack, police said.
Earlier today, two policemen were shot dead in a targeted attack in the Zarghoon Road area in Quetta.
Polio teams have been the target of militants after the Taliban spread rumours that the vaccination drives were a front for espionage or a conspiracy to sterilise Muslims.
At least 13 policemen and a civilian were killed in the Tehreek-i-Taliban Pakistan-claimed suicide attack near a polio centre.
