Gunmen on Saturday shot dead nine people in southeastern Iran, near the border with Pakistan.
A report by the semi-official Mehr news agency said the shooting took place at a house near the Iranian city of Saravan, and that the victims were not Iranian.
Meanwhile, no official media reported on the killings and no group has yet claimed responsibility for the attack, AP reported.
HalVash, an advocacy group for the population known as the Baluch, shared online images of what appeared to be the bodies of victims and said three other people were injured. He said they were Pakistani nationals and identified four of them, saying all the victims were workers at a car repair shop.
Last week, Pakistan launched retaliatory strikes in the same area, targeting militant hideouts, an attack that killed at least nine people. The attacks followed an attack by Iran on Tuesday in Pakistan that killed two children in the southwestern province of Balochistan.
