Iraqi Shi’ite paramilitaries take Baaj town west of Mosul from Islamic State

Shi’ite paramilitaries have captured the Iraqi town of Baaj from Islamic State, further shrinking the northern region under jihadist control as part of a U.S.-backed campaign to retake the city of Mosul, the Iraqi military said on Sunday.

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 Shi’ite 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.

Iraqi government armed forces are focussing their effort on dislodging insurgents from remaining pockets in Mosul, since 2014 Islamic State’s de facto capital in Iraq.

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.
