On 30 May, at least 12 men and four boys from the Jumaila tribe were extrajudicially executed. The victims had fled fighting in Sijir together with their families on 24 May and were temporarily sheltering with relatives in a rural area nearby. According to survivors, 49 after having fled fighting in their areas and having handed themselves over to a mixed force of armed men in different military and Federal Police uniforms, the armed men separated the men and older boys from the women and younger children, told them to line up and march forward, before shooting them dead.
At least 73 other men and boys from the Jumaila tribe seized from the area of Sijir on 27 May remain unaccounted for. Witnesses reported to Amnesty International during the organization's visit to camps in Anbar in August that the disappearance took place after a large group of Sijir residents handed themselves over to an armed force composed of men in military uniform, as forces were advancing on territories previously held by IS and residents were fleeing fighting, whom they assumed to belong to the PMU based on uniform insignia and coloured flags they were carrying. Some witnesses claimed to recognize the Kata'ib Hizbullah insignia.
PMU militias abducted, tortured and killed men and boys from the Mahamda tribe from Saqlawiya during operations to retake Falluja. 50 On 3 June, thousands of IDPs fleeing from Albu Akash in Saqlawiya were intercepted by a large force of the PMU, who took away some 1,300 men and older boys. Three days later, on 6 June, local Anbar officials told Amnesty International that they were handed over 605 of the abducted males bearing marks of torture. About a dozen survivors told Amnesty International that they had been held by PMU militias at what appeared to be an abandoned farm house, beaten with various objects including shovels and denied food and water. Former detainees told Amnesty International that they witnessed others being beaten to death or taken away by militiamen never to return.51
According to findings published on 11 June by an investigative committee established by the Governor of Anbar to look into abuses in Saqlawiya and al-Sijir, 49 people were killed; and an additional 643 remain missing amid fears for their lives and safety. 52 Former detainees interviewed by Amnesty International identified members of the Kata'ib Hizbullah – based on emblems on their uniforms and coloured flags - as among those responsible for the torture and killing of men from Saqlawiya.
