Armed militants opened fire indiscriminately at labourers while they were sleeping. The injured labourers were rushed to District Headquarter Hospital for medical treatment, Dawn online reported.
"No one has claimed responsibility for the attack," said Imran Qureshi, the District Police Officer (DPO) Turbat.
"It may be an act of target killing. All the victims received multiple bullet injuries," he added.
Labourers belonged to Sindh and were employed for construction of a bridge in the area.
Balochistan Chief Minister Abdul Malik Baloch arrived in Turbat to chair a high-level meeting on the incident and concerns regarding security.
Panic prevailed in the locality in the aftermath of the killings. Turbat, the home town of chief minister is considered to be one of the sensitive districts in Balochistan.
Instances of labourer killings have repeatedly taken place in Balochistan over the years. Last year in October, eight labourers were kidnapped from a poultry farm in Sakran area near the industrial town of Hub.
