ISIS Executes 232 near Mosul
(CNN) -- ISIS has "executed" 232 people near the Iraqi city of Mosul and taken tens of thousands of people to use as human shields against advancing Iraqi forces, the United Nations says.
The terror group carried out the mass killings Wednesday, punishing people who had defied its orders, a spokeswoman for the UN human rights arm told CNN.
"ISIS executed 42 civilians in Hammam al-Alil, south of Mosul. Also on Wednesday ISIS executed 190 former Iraqi security forces for refusing to join them, in the Al Ghazlani base near Mosul," said Ravina Shamdasani of the Office of the UN High Commissioner for Human Rights.
Another 24 former Iraqi security forces officers were reportedly killed Tuesday, the office said.
Since October 17, ISIS has taken tens of thousands of men, women and children from the outskirts of Mosul into the city. Shamdasani said the United Nations feared the group intended "to use them as human shields against the Iraqi forces advance on Mosul."
There have been other reported civilian deaths over the past week as ISIS tries to herd people into its last major stronghold in Iraq and the nation's second city against the Iraqi-led operation.
Iraqi forces advance from south
Reports of the latest ISIS atrocities came as Iraqi security forces reported further progress Friday in their advance from the south of Mosul.
Abdulrahman al Wagga, a member of the Nineveh provincial council, told CNN the security forces had taken the town of al Shura, about 30 kilometers (19 miles) south of Mosul, and had evacuated 5,000 to 6,000 civilians.
The area is being cleared of homemade bombs and booby traps, he said.
Iraqi security forces and federal police have also now "90% surrounded Hammam al-Alil," the largest town south of Mosul, Wagga said.
ISIS has used human shields before
Wagga said the Iraqi forces might storm Hammam al-Alil soon but it would depend on the situation on the ground since civilians were still present.
Reports indicate that ISIS has abducted at least 5,370 families from around al Shura and 150 more from around Hammam al-Alil, Shamdasani told a briefing in Geneva, Switzerland.
Another 160 families have reportedly been seized from around Qayyara, she said, and 2,210 families from the Nimrud area of Hamdaniya district.
"Forced out by gunpoint, or killed if they resist, these people are reportedly being moved to strategic locations where ISIL fighters are located," Shamdasani said, using an alternative acronym for ISIS.
Information received by the United Nations suggests some 60,000 people are currently living in Hammam al-Alil, an ISIS stronghold with a previous population of 23,000, she said.
The use of human shields is banned under international humanitarian law, and constitutes a violation of the right not to be arbitrarily deprived of life, the UN refugee agency said.
ISIS has used the same tactic in previous battles in Iraq, notably in Falluja in June.
'Depraved, cowardly' strategy
The UN High Commissioner for Human Rights, Zeid Ra'ad Al Hussein, said the terror group's "depraved, cowardly strategy is to attempt to use the presence of civilians to render certain points, areas or military forces immune from military operations, effectively using tens of thousands of women, men and children as human shields."
He also warned last week that ISIS fighters appeared to be using civilians in and around Mosul as human shields.
The commissioner urged those fighting ISIS not to carry out revenge attacks and called on the Iraqi government to ensure respect for the rule of law.
As the fighting around Mosul intensifies, growing numbers of civilians have sought to flee despite the risks involved.
The International Organization for Migration reported the Mosul operation had displaced 16,566 people as of Friday. Camps have been set up to accommodate an expected flood of desperate families.
ISIS 'killed brother for spying'
Civilians continued Friday to stream out of villages to the east of Mosul that ISIS had held until recent days.
Several people gave insight into life under ISIS rule, telling the Kurdish network Rudaw that militants had fired at them as they left a settlement near Darwish to the northeast of Mosul.
One woman said her brother had been killed after being accused of spying for the Peshmerga, or Kurdish fighters. She said women had been forced to wear gloves and be completely covered.
A young man told the network his brother had been killed because he had a cell phone and was allegedly a spy.
Iraqi forces are holding positions about 6 kilometers (3.7 miles) from the eastern side of Mosul.
Gen. Aly Al Saady told the al Iraqiya network his force would wait for troops on other fronts to close in on Mosul before launching an attack on the city. He said they had prepared safe corridors for civilians to get out of Mosul before starting the operation.
ISIS fighters killed
The United States and its allies have killed between 800 and 900 ISIS fighters in the Mosul campaign, US Army Gen. Joseph Votel said Thursday.
US military officials estimate that 3,000 to 5,000 ISIS fighters are defending Mosul, with an additional 1,500 to 2,000 ISIS soldiers in a zone outside the city.
The ISIS fighters face a 90,000-strong force of Iraqi government troops, Kurdish Peshmerga fighters and irregular militia soldiers -- but have had plenty of time to prepare their defenses.
The militants are using a "scorched earth" policy by destroying houses, buildings and bridges to slow down the advancing Iraqi security forces, said Wagga, the local leader.
