Iran's Revolutionary Guards killed six "armed bandits" in the country's southeast on Saturday, the force said on its website, in a second day of clashes in an impoverished and often restive region.
Three local members of the volunteer Basij militia fighting alongside the Revolutionary Guards were killed in the clashes, the statement said.
The Sistan-Baluchistan province near the Pakistani and Afghan borders has long been plagued by unrest from both drug smuggling gangs and extremist militants fighting the country's authorities.
On Friday, Revolutionary Guards shot dead three men believed to have been involved in the killing of two Guards on December 25, according to Iranian media.
