At least five labourers were killed and two others critically injured on Wednesday in a targeted attack carried out by two motorcycle-borne gunmen at a construction site in Pakistan's restive Baluchistan province.
"There were a dozen or more labourers working at the time and most of them rushed to safety but five of them were killed on the spot," Mohtashim Chengazi, a senior police official said.
He said two other labourers were injured and had been rushed to a hospital as they were in critical condition.
"The casualties could rise," he added.
So far no militant, sectarian or separatist group has claimed responsibility for the attack, but in the past separatists have targeted labourers from other provinces working on the Pakistan-China Economic Corridor projects in the province.
In May, unknown gunmen had killed six labourers in the remote area of Lajjey in the province.
