Pakistan dam builders shot dead in Balochistan

At least 20 workers accused of working on an army-backed dam construction site in the south-western Pakistani province of Balochistan have been shot dead by a large group of gunmen, officials say.

Police say that the gunmen overpowered eight security guards, and shot the labourers on Friday night.

A separatist group said it was responsible for the attack.

Taliban militants, Baloch separatists and other groups fight in the Balochistan region, which borders Iran.
