WASHINGTON (Sputnik) — "Our [US] operational objective is to place pressure across the entire breadth and depth of this battlefield," Warren said.
Pressure, Warren added, creates movement and movement creates additional targets.
Daesh (Islamic State), which is outlawed in Russia and a number of other countries, seized the northern Iraqi city of 2.5 million in June 2014. Mosul has since become the de facto Iraqi capital of the terrorist group.
The Kurdish media network Rudaw reported earlier this week that US forces are setting up a military unit of Sunni Arab fighters for a future offensive to retake Mosul. In addition, Rudaw reported that Turkey is also training 9,000 fighters for the battle.
