Some of the labourers were working on a mobile tower while others were sleeping in tents when gunmen opened fire at them, reported AFP. There was no immediate claim of responsibility over the incident.
Two of the six men, Amanat and Javed, were brothers, while others shot dead include Mohammad Shahzad, Muhammad Waqas, Fajhar Rafeeq and Mazhar Fareed.
The bodies of the labourers have been returned to their hometown in Okara for burial purposes.
Militants have repeatedly targeted labourers from Punjab and Sindh working in various parts of Balochistan.

"All the labourers were shot at close range," said senior levies official Muhammad Zareef, adding that the shooters were travelling on a motorcycle.
