Tunisia's official TAP news agency says the death toll from violent clashes in the southwest of the country has been raised from five to seven.
Another 90 people have been injured in the violence in Metlaoui, which has raged since Friday and pitted members of different tribal clans against one another.
A rumor that the depressed mining region's main employer had changed its recruitment policy to favor one tribe reportedly sparked the violence.
Five people were initially reported dead on Saturday, with two additional victims dying later Saturday and Sunday.
Stores in Metlaoui have been torched and pillaged, and the staff of the local hospital fled after they were threatened by angry townspeople. A curfew is in effect.
