Militants accused men and women of the Al Bu Nimr tribe of retaliating against them after being displaced from their homes when the group seized the Anbar town of Hit last month, al-Issawi said.

"These killings are taking place almost on a daily basis now in the areas under the control of the [ISIS] group and they will continue unless this terrorist group is stopped," al-Issawi told The Associated Press.

An official in the Anbar governor's office confirmed the death toll. He spoke on condition of anonymity as he is not authorized to brief journalists.

On Thursday, authorities found the bodies of 48 Sunni tribesmen killed by ISIS in Anbar.

1,273 Iraqis killed in violence last month: UN

ISIS has overrun a large part of Anbar province in its push to expand its territory, which currently current stands at about one-third of both Iraq and Syria. Officials with the Iraqi government, as well as officials with the U.S.-led coalition targeting the extremists, repeatedly have said that Iraqi tribes are key in the fight against ISIS since they are able to penetrate areas inaccessible to airstrikes and ground forces.

Meanwhile Saturday, the United Nations mission in Baghdad said that at least 1,273 Iraqis were killed in violence in October, a slight increase compared to last month amid ISIS's assault.

The UNreport said violence killed 856 civilians and 417 members of Iraq's security forces, while attacks wounded 2,010 Iraqis.

The worst-hit city was Baghdad, with 379 civilians killed, the report said.

The UNfigures do not take into account causalities in Anbar province nor some other militant-held parts of Iraq.

The UNhas said September's death toll was 1,119 Iraqis killed.
