QAYYARAH, Iraq -- Iraqi paramilitary forces launched an operation Saturday to cut the Islamic State group’s supply lines between its Mosul bastion and neighbouring Syria, opening a new front in the nearly two-week-old offensive.
Forces from the Hashed al-Shaabi, a paramilitary umbrella organisation dominated by Iran-backed Shiite militias, have largely been on the sidelines since the launch of the operation to retake Mosul.
But on Saturday, they began a push on the town of Tal Afar on the western approach to the city, the only side where ground forces, which have advanced from the north, east and south, are not yet deployed.
“The operation aims to cut supplies between Mosul and Raqa and tighten the siege of (IS) in Mosul and liberate Tal Afar,” Hashed spokesman Ahmed al-Assadi told AFP, referring to IS’s main stronghold in Syria.
Assadi said the operation was launched from the Sin al-Dhaban area south of Mosul and aimed to retake the towns of Hatra and Tal Abta as well as Tal Afar.
The drive toward Tal Afar could bring the fighting perilously close to the ancient city of Hatra, a UNESCO world heritage site that has already been vandalised by IS.
Though it was not mentioned by name, the operation may also pass near the ruins of Nimrud, another archaeological site that has previously been attacked by IS.
The involvement of Shiite militias in the Mosul operation has been a source of contention, although some of the Hashed’s top commanders insist that do not plan to enter the largely Sunni city.
Iraqi Kurds and Sunni Arab politicians have opposed their involvement, as has Turkey which has a military presence east of Mosul, despite repeated demands by Baghdad for the forces to be withdrawn.
Turkish President Recep Tayyip Erdogan Saturday warned Shiite militias against attacking Turkmen residents of Tal Afar.
“If the Hashed al-Shaabi sow terror there, then our response will be different,” Erdogan said, according to the state-run Anadolu news agency, without specifying what measures would be taken.
Relations between the Hashed and the US-led coalition fighting IS are also tense, but the paramilitaries enjoy widespread support among members of Iraq’s Shiite majority.
Tal Afar was a Shiite-majority town of mostly ethnic Turkmens before the Sunni extremists of IS overran it in 2014, and its recapture is a main goal of Shiite militia forces.
As the Hashed push on Tal Afar got under way, Iraqi forces battled IS in Al-Shura, an area south of Mosul with a long history as a militant bastion that has been the target of fighting for more than a week.
Iraq’s Joint Operations Command later announced “the complete liberation of Al-Shura area,” saying that security forces advancing from four different sides had now linked up in the area.
The offensive operations came despite an assertion from the US-led coalition on Friday that Iraqi forces were temporarily halting their advance on Mosul for a period expected to last “a couple days.”
