Islamic State militants have executed at least 50 more tribesmen in Iraq's Anbar province as part of a mass killing campaign being carried out by the group for resisting IS rule.
Local sources say the shooting of members of the Sunni Muslim Al Bu Nimr tribe occurred on Friday.
Militants accused the men and women of the tribe of retaliating against them after being displaced from their homes when the group seized the Anbar town of Hit last month, Anbar councilman Faleh al-Issawi said.
A few days ago, Iraqi officials said 150 bodies from that tribe, which resisted the Islamic State advance west of Baghdad, were found buried in a mass grave near the city of Ramadi.
More than 70 others were dumped near Hit.
A witness reported at the time that one of the Islamic State fighters said the executions were punishment for "anybody fighting the Islamic State." IS militants are also Sunnis.
The Islamist group has overrun large areas of Anbar province in its push to expand its territory, which currently stands at about one-third of Iraq and Syria.
Officials with the Iraqi government, as well as those with the U.S.-led coalition targeting the extremists, repeatedly have said that Iraqi tribes are key elements in the fight against the Islamic State group since they are able to penetrate areas inaccessible to airstrikes and ground forces.
Meanwhile, U.S. and partner nation military forces have launched five air strikes against Islamic State militants near Kobani, Syria and five in Iraq since Friday, United States Central Command said on Saturday.
The strikes in Iraq destroyed an Islamic State vehicle southwest of the Mosul Dam and hit four vehicles and four buildings used by militants near Al Qaim, Centcom said.
Officials say the strikes were conducted as part of Inherent Resolve, the operation to eliminate IS and the threat it poses to Iraq, the region and the wider international community.
Among the coalition nations conducting airstrikes in Iraq are the U.S., France, the United Kingdom, Australia, Belgium, Denmark and the Netherlands.
