According to the officials, the Iraqi army is deploying thousands of soldiers to a northern base in preparation for operations to retake the Islamic State group's hub of Mosul. IS seized Mosul in June 2014 and except for air strikes has held Iraq's second city largely unopposed for over 18 months as the country's security forces battled the jihadists in other areas.
According to a staff brigadier general, "Units from the Iraqi army have begun arriving to a military base near the Makhmur district to start launching initial military operations toward Mosul."
"There are three brigades located in that base now," and their number will eventually reach 4,500 soldiers, the officer said, adding that troops from the 15th and 16th division will take part in operations to retake Mosul.
Makhmur lies around 70 kilometers southeast of Mosul.
The official also stated that the initial aim is to completely sever IS supply lines between Mosul and areas farther south including Hawijah in Kirkuk province and areas near Baiji in Salaheddin.
A Kurdish official said that most of the soldiers deployed to the area, which is located within territory controlled by Iraqi Kurdistan, are ethnic Kurds from the Iraqi army.
Halgurd Hekmat, a spokesman from the ministry responsible for the autonomous region's forces, said, "These forces came with the approval of the presidency and government of the Kurdistan region of Iraq."
Hekmat also stated that the base will be for both soldiers and aircraft. Multiple Iraqi divisions collapsed during the early days of IS's 2014 offensive, which overran large areas north and west of Baghdad.
With the help of US-led air strikes and training, Iraqi forces have since regained significant areas from IS, but Mosul will be the most difficult battle of the war against the jihadists.
