QUETTA, Pakistan (AP) — Attackers fatally shot seven barbers before dawn Thursday in a home in a volatile province in southwestern Pakistan, police and a government official said.

The killings occurred near the port city of Gwadar in Baluchistan province, police official Mohsin Ali said. All of the barbers were from Punjab province and lived and worked together.

Provincial Interior Minister Ziaullah Langau condemned the killings and said police were investigating who was behind the attack.

There was no immediate claim of responsibility. Separatists in Baluchistan have often killed workers and others from Punjab as part of a campaign to force them to leave the province, which for years has experienced a low-level insurgency by the Baluchistan Liberation Army and other groups demanding independence from the central government in Islamabad. Islamic militants also have a presence in the province.
