- The gunmen targeted workers who were building a bridge
- Three other workers were injured
The gunmen targeted workers who were building a bridge in Turbat in Balochistan province, said Imran Qureshi, a local police officer.
They sped away after the attack, which left three other workers injured.
"It was an act of targeted killing," Qureshi said.
The workers belonged to Pakistan's Sindh province.
There was no immediate claim of responsibility for the attack. In the past, Baloch separatists have targeted area security forces and laborers.
