Eight newborns were among 18 civilians killed when Iraqi warplanes hit a hospital in the northern town of Hawija, which is controlled by Islamic State militants.
At least 16 people were also wounded in the bombardment on Friday, a hospital official told independent Iraqi website Alsumaria News.
The hospital building was heavily damaged, while the premature baby ward collapsed, according to the report.
“Local residents helped in retrieving the bodies from the rubble and transporting the wounded to a nearby hospital,” the official added on condition of anonymity.
There was no official comment.
Hawija is located near the oil-producing city of Kirkuk, around 250 kilometres north of the capital Baghdad.
The Islamic State seized Hawija in June, when its forces captured huge areas in northern Iraq.
Iraqi and Kurdish troops, backed by air cover, have in recent weeks wrested back several towns from the Sunni extremist group.
Ten NATO allies and partners also agreed on Friday to form a coalition to fight Islamic State.
