Karachi, Oct 25: Unidentified gunmen on Friday abducted 18 workers from a construction company’s site in the Khuzdar district of the restive Balochistan province, security officials said. The armed men also set several vehicles on fire before taking away the 18 labourers at gunpoint. The armed men first overpowered the site guards and then took the workers to an undisclosed location, officials said. In a second such incident in the last five days, labourers mostly belonging to other provinces have been kidnapped at gunpoint.
