ISIL terrorists are reported to have slaughtered dozens of members of the Albu Nimr tribe, which took up arms against them in Anbar.

On Monday, tribal leader Naim al-Kuoud al-Nimrawi told AFP that IS "executed 36 people, including four women and three children" on Sunday alone.

Accounts have varied as to the number and timings of the executions, but sources have spoken of more than 200 people murdered in recent days.

A police officer and an official gave figures of more than 200 to 258 people killed, while Iraq's human rights ministry put the toll at 322 and a tribal leader said 381 were executed.

The mass killings appear aimed at discouraging resistance from powerful local tribes in Anbar, where ISIL overran large areas in June.
