Militants from Islamic State (IS) have killed at least 50 members of an Iraqi tribe in western Anbar province, officials and tribal leaders say.
The men and women from the Al Bu Nimr tribe are reported to have been lined up and shot in retaliation for resisting the jihadists.
A number of people from the same tribe were also found dead in mass graves earlier this week.
IS militants control large areas of Iraq and neighbouring Syria.
Meanwhile, AFP news agency quoted the UK-based Syrian Observatory for Human Rights as saying that at least 100 IS fighters had been killed in three days of fighting for the strategic Syrian border town of Kobane.
On Friday, some 150 Iraqi Kurdish Peshmerga fighters crossed from Turkey to join Syrian Kurds who have been defending the town against IS for six weeks.
The Observatory says that more than 950 people have died in the battle, more than half of them from IS.
