Iraqi special forces have moved in on the ISIS-held city of Mosul.
Mosul is a vital hub for ISIS, and an offensive attack by Iraqi troops began in mid-October. Recent numbers from the U.S.-led coalition commander put about 3,000 to 5,000 ISIS fighters inside the city.
Car bombers are reportedly trying to stop the troop's advances.
The battle for Mosul has been going on for quite some time. ISIS overtook the city more than two years ago. And in March, the Iraqi government announced its plan to reclaim the area.
