Iraqi forces are set to launch an offensive to drive Islamic State militants out of Anbar province.
The start of the operation - backed by Shi'ite and Sunni forces - was announced on state television, although no further details were given.
Iraqi forces will retake the city of Ramadi from Islamic State militants "in days", the country's prime minister has said.
Thousands of civilians fled the city, which lies around 78 miles from Baghdad, after insurgents seized control.
"It makes my heart bleed because we lost Ramadi, but I can assure you we can bring it back soon," Haider al-Abadi told the BBC.
He defended the Iraqi military amid criticism from US Defence Secretary Ashton Carter, saying they were overwhelmed by the "onslaught" of IS.
"They have the will to fight but when they are faced with an onslaught by Daesh [IS] from nowhere, with armoured trucks packed with explosives, the effect of them is like a small nuclear bomb - it gives a very, very bad effect on our forces."
