Iraqi forces and Shi'ite paramilitaries captured an air base from Islamic State on Monday, the army said, gaining a strategic foothold in the north of the country as they push towards the town of Hawija.
Iraq launched an offensive on September 21 to dislodge Islamic State from Hawija, which lies west of the oil city of Kirkuk and is one of two areas of the country still under the control of the militant group.
Iraqi army commanders said the Rashad air base, which is around 30 km (20 miles) south of Hawija, was used by the militants as a training camp and logistic base.
Militants took control of the air base after the Iraqi army collapsed in 2014 in the face of the Islamic State offensive.
"After quick rehabilitation works, the air base will play a key role for Iraqi forces by allowing helicopters to transport soldiers and arms in any future operation to maintain security in the north," said army Lieutenant Colonel Salih Yaseen.
"The air base will help to put an end to the terrorists' pockets hiding in mountainous areas near Kirkuk and remove any possible threat to the energy facilities and oilfields."
Hawija, north of Baghdad, and a stretch of land along the Syrian border, west of the Iraqi capital, are the last stretches of territory in Iraq still in the hands of Islamic State.
Islamic State's self-declared caliphate effectively collapsed in July, when US-backed Iraqi forces captured Mosul, the group's de facto capital in Iraq, after a gruelling nine-month battle.
