The terrorists used light weapons and the cover of darkness to target the PMU fighters east of Tikrit, the capital of Iraq’s Saladin province, on Saturday.
The deadly ambush came two days after a twin suicide attack claimed by Daesh killed 32 people in Baghdad.
One of the Hashd al-Sha’abi officers, named Abu Ali al-Maliki, told AFP that the attack targeted the PMU’s Brigade 22.
He said the brigade commander was among those killed before reinforcements from the federal police came to the unit’s aid.
PMU security sources said the total toll was 11 dead and 10 wounded.
There was no immediate claim of responsibility, but security sources interviewed by AFP blamed Daesh.
‘Saudi terrorists enter Iraqi’
Meanwhile, a member of the Iraqi Parliament’s Security and Defense Commission announced on Saturday that a group of Saudi terrorists have entered the Iraqi territory via the Arar border crossing with the KSA.
Speaking to Iraq’s al-Maalomah news website, Mehdi Taqi urged security forces to control Arar crossing and closely inspect the checkpoint as it has turned into a gate for arrival of terrorists and suicide attackers in Iraq.
He also blamed Iraqi Prime Minister Mustafa al-Kadhimi for the Thursday blasts in Baghdad, and said the premier has failed in controlling the country’s security conditions.
