Iraq pauses their advance on Mosul after start of a massive operation

Iraqi and Kurdish commanders on Tuesday said they paused their advance on Mosul, a day after the start of a massive operation to retake the Islamic State-held city, which is expected to take weeks, if not months.

The front lines to the east of Mosul were largely quiet, a day after Iraqi Kurdish forces advanced amid a barrage of US-led airstrikes and heavy artillery.

"We are just holding our positions," said Col. Khathar Sheikhan, of the Kurdish forces known as the peshmerga, which captured a handful of villages east of Mosul on Monday. "The Iraqi army will now advance past our arenas of control."

"We have achieved our objectives," he said. But an Iraqi special forces commander said his troops have delayed an advance following a request from Kurdish forces for more time to achieve their goals.

It was not immediately possible to reconcile the conflicting accounts. Brig Gen Haider Fadhil said his men had planned to move at dawn, but postponed the operation. He said Iraqi army and Kurdish commanders would meet later on Tuesday.

Iraqi Prime Minister Haider al-Abadi had announced the long-awaited offensive before dawn Monday, vowing to liberate the city from more than two years of extremist rule. Mosul is Iraq's second largest city and the IS group's last major urban bastion in the country.

The large and complex battle for Mosul is expected to last weeks or months. It will involve more than 25,000 troops, including the Iraqi army, the Kurdish peshmerga, Sunni tribal fighters and Shiite militias. The U.S. military is providing air support and playing a supporting role on the ground.

A spokesman for the US-led coalition said the operation was proceeding as planned and that Iraqi forces were making "excellent progress."

"There's no pause in efforts to liberate Mosul. Troops are on the move on various axes of advance toward the city," said Col. John Dorrian. "Some commanders have reached their objectives ahead of schedule after encountering light-to-moderate resistance."

The Iraqi Army's 9th Division meanwhile reached the outskirts of the town of al-Hamdaniyah, south of Mosul, but stopped advancing because of snipers and suicide bombers, according to a military officer. The Federal Police reached al-Houd village to the east, another officer said.

Both spoke on condition of anonymity as they were not authorised to brief the media.

By the end of the day on Monday, Kurdish forces had retaken some 200 square kilometers, according to Massoud Barzani, the president of Iraq's largely autonomous Kurdish region.
