Islamic State militants have in recent days executed dozens of prisoners taken from villages the group has been forced to abandon by an Iraqi army advance on the city of Mosul, officials in the region said on Wednesday.
Most of those killed were former members of the Iraqi police and army who had lived in areas under Islamic State control south of Mosul, Abdul Rahman al-Waggaa, a member of the Nineveh provincial council, told Reuters.
The militants forced them to leave their homes with their families, and took them to the town of Hammam Al-Alil, 15 km (9 miles) south of Mosul, where the executions took place, he said in Erbil, the capital of the Kurdish region, east of Mosul.
The men were shot dead, he said, quoting the testimony of remaining residents of the villages and people displaced from the area.
The executions were meant "to terrorize the others, those who are in Mosul in particular", and also to get rid of the prisoners, he said.
"Daesh (Islamic State) was taking families from each village it left," said Waggaa.
Separately, Hoshiyar Zebari, an influential Kurdish politician, told Reuters in Erbil that at least 65 people had been executed by Islamic State south of Mosul three days ago.
Revolt
The militants started rounding up hostages in the villages of Al-Hudd and Al-Lazzaga, after a revolt broke out against them a week ago to aid the army's advance, said Zebari, a former Iraqi finance minister and foreign minister.
More than 20 were put to death as punishment in two villages located just north of the town of Qayyara, he said.
Families of the executed hostages are being held in Hammam al-Alil or in Mosul, he said.
U.N. human rights spokesman Rupert Colville on Tuesday said Islamic State fighters had reportedly killed scores of people around Mosul in the last week.
Colville said security forces discovered the bodies of 70 civilians in houses in Tuloul Naser village south of Mosul last Thursday.
Islamic State also reportedly killed 50 former police officers outside Mosul on Sunday, he said.
Iraqi army and Kurdish Peshmerga forces on Oct. 17 launched an offensive on Mosul, Islamic State's last major city stronghold in Iraq.
