Iraqi security forces have recaptured Mosul airport, a key part of the government's offensive to drive the Islamic State (IS) from the western half of the city. <br/><br/>The operation took four hours. IS continued to fire mortars at the airport from further inside the city after losing the ground to the army. A military spokesman said, the jihadists have also entered a nearby military base amid further clashes. Eastern Mosul was retaken last month.
