A Yazidi militia group, to seek revenge for the atrocities on its people, attacked a Sunni village and killed at least 21 persons, including several children, an Amnesty International report has revealed.

The Amnesty International report, "A deadly spiral of sectarian violence - a year on from IS onslaught on Iraq", released on Wednesday noted that the Yazidi militia carried out a "revenge attack" on two Arab villages on 25 January, 2015.

"Virtually not a single house was spared. Half of those killed were elderly or disabled men and women and children," the report noted. During the onslaught, 40 Sunni residents were abducted, 17 of whom are still missing.

Isis, which is a Sunni militant group has killed thousands of Yazidi men and women in Iraq. Hundreds of Yazidi women and girls have been taken as sex slaves by the radical group as it sees the minority community as the worshippers of devil.

The father of two of the victims -- a 15-year-old boy and his 20-year-old brother from Jiri -- told Amnesty International that after killing his sons, the Yazidi militia dumped their corpses in a nearby village. His third son, a 12-year-old, was shot four times in the back, chest, arm and leg but he survived miraculously.

Nahla, a 34-year-old mother of five from Jiri, who lost her husband and a son in the attack claimed that even her baby had a narrow escape when a bullet pierced the blanket she had wrapped him in as she carried him in her arms.

"We could not imagine the assailants would target the old and the sick but they did," said a man, describing how his 66-year-old father was shot dead in his wheelchair.

The report citing Iraqi residents noted that members of the Peshmerga and Asayish security forces of the Kurdistan Regional Government (KRG), who were present at the time of the attack, did little to stop the killings.
