Iraqi forces have captured the town of Hawija and the surrounding area from ISIL, one of their last strongholds in Iraq.

With the capture of Hawija, the only area that remains under control of the Islamic State of Iraq and the Levant (ISIL, also known as ISIS) group in Iraq is a stretch alongside the western border with Syria.

Prime Minister Haider al-Abadi said in Paris on Thursday that "I want to announce the liberation of the city of Hawija today," calling it a "victory not just of Iraq but of the whole world".

He said that the fight against ISIL is now focused on the border zone with Syria.

The offensive was carried out by US-backed Iraqi government troops and Iranian-trained and armed Shia paramilitary groups known as Popular Mobilisation Forces(PMF).

"The army's 9th armoured division, the Federal Police, the Emergency Response division and … Popular Mobilisation liberated Hawija," said a statement from the joint operations commander, Lieutenant-General Abdul Ameer Rasheed Yarallah, on Thursday.

Major General Raid Shaker Jawdat, commander of Iraq's Federal Police, said, "The federal forces liberated the district of Hawija, the Hawija hospital as well as the Askari, Nidaa and Thawra neighbourhoods, and are in control of the centre of the province of Hawija in full".

Strategic importance

Hawija lies between two main routes north of Baghdad; one leading to Kirkuk and the autonomous Kurdish region, the other to Mosul and further on to the Iraqi border with Syria and Turkey.

Its geographical location in the oil-rich province of Kirkuk and its proximity to Mosul and the Iraqi Kurdish region
