The United Nations has asserted that the ISIS has executed 232 people and taken thousands of people to use as human shields against advancing Iraqi forces near Mosul.
A spokeswoman for the UN's human rights arm told CNN that the terror group had carried out the mass killings on Wednesday as a punishment for those people who defied its orders.
"On Wednesday 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.
She further said that since October 17, ISIS has taken "tens of thousands" of men, women and children from the outskirts of Mosul into the city, adding that the UN feared their purpose was to be to used as human shields against the Iraqi forces advance on Mosul.
There have been other reports over the past week of civilians being murdered as ISIS tries to herd people into its last stronghold in Iraq.
Iraqi Security Forces reported further progress Friday in their advance from the south of Mosul, the country's second city.
