The Latest on the Iraqi government forces' battle to take the western half of Mosul from the Islamic State group (all times local):
Iraqi police officials say the country's militarized federal police forces have entered Mosul International Airport, taking over the runway amid fierce clashes with the Islamic State group.
Thursday's advance is part of a major assault that started five days ago to drive IS militants from the western half of Mosul, Iraq's second-largest city.
Two police officers say the airport buildings are now under fire from the Iraqi police forces. They would not provide more details but said troops from the U.S.-led coalition are with the advancing forces, though they didn't specify the nationalities of the foreign forces.
