MOSUL, Iraq (AP) -- Iraqi troops backed by U.S.-led airstrikes pushed deeper into eastern Mosul on Thursday in a multi-pronged assault after a two-week lull in the operation to retake the Islamic State-held city.
Elite special forces pushed into the Karama and Quds neighborhoods, while army troops and federal police advanced into nearby Intisar, Salam and Sumor neighborhoods. Smoke rose across the city as explosions and machine gun fire echoed through the streets.
Stiff resistance by the militants, civilians trapped inside their houses and bad weather have slowed advances in the more than two-month-old offensive to recapture Iraq's second largest city, the extremist group's last urban bastion in the country. It is the biggest Iraqi military operation since the 2003 U.S.-led invasion.
In an interview with The Associated Press on Tuesday, Lt. Gen. Abdul-Wahab al-Saadi, commander of the special forces in eastern Mosul, said his forces have been bolstered by reinforcements and are now less than 3 kilometers (2 miles) from the Tigris River, which slices the city in half. A U.S.-led coalition airstrike this week destroyed the last remaining bridge over the river.
The special forces, officially known as the Counter Terrorism Service, have done most of the fighting, pushing in from the east. But regular army troops on the city's southeast and northern edges, as well as militarized federal police farther west, have not moved in weeks, unable to penetrate the city.
The troops have faced grueling urban fighting, often house to house against IS militants who have had more than two years to dig in and prepare. Even in districts that have been recaptured, Iraqi troops have faced surprise attacks, shelling and car bombs. The extremists have launched more than 900 car bombs against Iraqi troops in and around Mosul. Al-Saadi said 260 targeted his men.
He said he expected Iraqi forces would drive IS from Mosul and the rest of Nineveh province within three months. Iraqi leaders had previously vowed to drive the extremists from Mosul by the end of the year.
IS captured Mosul in the summer of 2014, when it swept across much of northern and central Iraq, and the group's leader declared the establishment of its self-styled caliphate from the pulpit of a Mosul mosque.
The city is still home to around a million people. Some 120,000 have fled since the operation began on Oct. 17, according to the United Nations.
