Iraqi forces have recaptured territory from Islamic State militants which links the recently recaptured city of Ramadi to a major army base in western Iraq, the military says.
A statement broadcast on state television said the army, police and counter-terrorism forces had retaken several areas including the town of Husaiba al-Sharqiya, about 10km east of Ramadi.
"[Our forces] also managed to open the road from Ramadi to Baghdad which passes through al-Khaldiya," the statement added, referring to a highway that links the city to the Habbaniya base where US-led coalition forces are located.
Iraq's army declared victory in December over IS in Ramadi, the provincial capital west of Baghdad. It was the first major gain for the US-trained force since it collapsed in the face of an assault by the militants in 2014.
Government forces are still dismantling bombs planted in Ramadi, and much of the city's infrastructure needs to be rebuilt.
Tuesday's advance (local time) boosts government efforts to close in on Falluja, the IS stronghold located between Ramadi and Baghdad which is besieged by the army and Iranian-backed Shi'ite militias.
The ultra-hardline Sunni militants of IS swept through a third of Iraq in 2014, declaring a caliphate in Iraq and Syria, carrying out mass killings and imposing a draconian form of Islam.
