Shia paramilitaries have captured the Iraqi town of Baaj from Islamic State, further shrinking the northern region under Islamic State control.

Eight months into the Mosul offensive, Islamic State (IS) militants have been dislodged from all of the city except an enclave along the western bank of the Tigris river.

IS’s grip on the Iraqi side of the northern region along the border with Syria, a desert area where Iraqi and U.S. sources believe IS leader Abu Bakr al-Baghdadi is hiding, has been ebbing as forces fighting on the side of Iraq’s government have advanced.

The Iraqi air force provided cover for the thrust into Baaj of the Shi’ite paramilitaries known as Popular Mobilisation, said a statement from the Iraqi joint operations command.

Popular Mobilisation is steered by neighbouring Shia regional power Iran, an adversary of the United States, but is playing a part in the campaign to defeat Islamic State, an enemy of both, in Mosul and the surrounding province of Nineveh.

While reporting nominally to Iraq’s Shi’ite-led government, Popular Mobilisation has Iranian military advisers, one of whom died last month fighting near Baaj.

Securing border territory between Iraq and Syria is important for Iran to reopen a land route to supply Syrian President Bashar al-Assad’s army with weapons in his protracted war with rebels and militants.

A statement published by Popular Mobilisation announcing the capture of Baaj came from Abu Mahdi al-Muhandis, a prominent leader of the paramilitary with longstanding ties to Iran.

Iran has helped to train and organise thousands of Shi’ite militiamen from Iraq, Afghanistan and Pakistan in Syria’s war. Fighters from Lebanon’s Shi’ite Hezbollah are also working closely with Iranian military commanders in Syria.

U.S. and Iraqi officials believe IS leader al-Baghdadi has left operational commanders behind with diehard followers to fight on in Mosul and is now focusing on his own survival.
