MOSUL, Iraq — The Islamic State group is striking back as Iraqi forces are on the cusp of full victory in Mosul, sending women suicide bombers to target soldiers as the battle for the country's second-largest city nears its end. At least 15 people were killed in the latest assaults across Iraq, officials said Monday.

On Monday morning in Mosul's Old City neighborhood — the scene of the Islamic State's last stand, where soldiers are fast closing in on the last remaining pocket of militants — two women suicide bombers, hiding among a group of fleeing civilians, targeted Iraqi troops, killing one soldier and wounding several others.

And at a camp for displaced people in Iraq's western Anbar province, a suicide bomber dressed in a woman's all-covering robe killed 14 Sunday evening, a provincial official said.

After days of fierce battles, the militant-held territory in Mosul is rapidly shrinking, with the Islamic State now controlling just about 0.40 square miles in all.

Using women as suicide bombers is apparently the latest tactic by the militants, Sgt. Ali Abdullah Hussein told The Associated Press as he returned from the front line, his troops carrying the body of their slain comrade wrapped in a blanket.

"They appeared from the basement [of a building], and they blew themselves up," Hussein said of the two women bombers.

The attack happened in the area of the destroyed al-Nuri Mosque, which was the focus of the Iraqi forces' push last week.

Over the past three days, Hussein said at least four such attacks have targeted Iraqi forces as hundreds of Mosul's civilians are fleeing the battles in the Old City's congested streets.

The Islamic State overran Mosul in a matter of days more than three years ago. The U.S.-backed offensive to retake the city was launched last October and has lasted nearly nine months, although Iraqi political and military officials had vowed that victory would be declared by the end of 2016.

Iraqi forces launched the operation to retake the Old City in mid-June and after a dawn push last Thursday, they retook the area around the al-Nuri Mosque, which the militants had blown up just a few days earlier.

After the Iraqi forces retook the landmark al-Nuri Mosque, Prime Minister Haider al-Abadi declared an end to the Islamic State's so-called caliphate and pledged victory was "near."
