Iraqi forces on Saturday were clearing mines in Falluja after driving the Islamic State group (ISIL) from most of the city, one of its last remaining strongholds in the Anbar province west of Baghdad,
The announcement comes nearly four weeks after the start of a US-backed offensive that led to the exodus of tens of thousands of residents.
Nearly four weeks after the start of a US-backed offensive, Iraq’s army says it has recaptured the main government headquarters in central Falluja.
The 50,000 civilians still trapped in ISIL controlled Falluja are the main victims of the city under siege.
With Sh'ite militias doing much of the heavy fighting in Iraq against ISIL, there are concerns they will alienate the Sunni communities they are trying to save from the Islamic extremists.
There has been no let-up in the Iraqi military offensive to drive ISIL out of Falluja.
At least 50,000 civilians are thought to be still inside the city, which is around 65 kilometres west of Baghdad.
Iraqi forces have begun shelling ISIL targets as the fight for Fallujah rages through a second day.
Iraqi forces have begun storming Fallujah, the first city to fall to ISIL, more than two years ago.
