BAGHDAD (AFP) - Iraqi troops and militia looted and burned homes and destroyed villages after breaking the Islamic State in Iraq and Syria (ISIS) group's months-long siege of a Turkmen town last August, Human Rights Watch said on Wednesday.
"Following the operations to end the Amerli siege, pro-government militias and volunteer fighters as well as Iraqi security forces raided Sunni villages and neighbourhoods around Amerli in Salaheddin and Kirkuk provinces," the New York-based group said in a report.
"During the raids, militiamen, volunteer fighters and Iraqi security forces looted possessions of civilians who fled fighting during the onslaught on Amerli, burned homes and businesses of the villages' Sunni residents," HRW said.
They also "used explosives and heavy equipment to destroy individual buildings or entire villages," it added.
HRW said that many of the villages targeted in the raids were ones that ISIS Islamists had either passed through or used as bases to attack Amerli.
"Iraq can't win the fight against (ISIS) atrocities with attacks on civilians that violate the laws of war and fly in the face of human decency," its deputy Middle East and North Africa director, Joe Stork, said.
"Militia abuses are wreaking havoc among some of Iraq's most vulnerable people and exacerbating sectarian hostilities." ISIS spearheaded an offensive last June that overran large areas north and west of Baghdad, sweeping security forces aside.
Reeling from the assault, Baghdad turned to Popular Mobilisation units - paramilitary forces that are dominated by pre-existing Shiite militias.
The units have played a key role in the fight to drive ISIS back, but relying on such groups further entrenches them in Iraq, giving them an expanded power base that will be difficult to dislodge.
