Clashes between members of two local tribes in Iraq's capital Baghdad have killed at least six people, including four policemen who intervened in the violence, the interior ministry said on Sunday.
Iraqi security officials, speaking to AFP on condition of anonymity, said that the clashes late Saturday erupted over increased fees for a private power generator.
The vast majority of Iraqis rely on private generators to compensate for daily long power cuts to public electricity.
The violence Saturday in Baghdad's Saada area resulted in the deaths of four police officers, two of them commanders, after they had intervened to disperse a "tribal dispute", the interior ministry said, revising an earlier toll.
A security official, requesting anonymity because he was not authorised to brief the media, said the toll was updated after two policemen succumbed to their injuries.
Another nine officers were wounded, the ministry said.
It said the force was attacked by "those who started the clashes", and returned fire that killed two people.
Five of those involved in the clashes were wounded and several arrested, the ministry said.
