Yarallah also said that the Iraqi forces sustained 115 martyrs and 679 wounded during the 12-day battles to liberate Tal Afar and its surrounding areas, including the towns of Mahalabiyah and Ayadhiyah.

“Those who take a look at this figure (Iraqi forces casualties) will realize that fierce battles took place in Tal Afar area,” Yarallah said.

The troops evacuated a total of 40,758 people from the city of Tal Afar and surrounding areas before and during the offensive, 18,822 before August 20 and 21,936 others during the 12-day offensive, Yarallah said.
