Iraqi government forces have made some gains in their efforts to retake Falluja, which is under the control of so-called Islamic State (IS) militants.
They are being supported by US-led coalition airstrikes, which the US said on Friday had targeted and killed the group's commander in Falluja.
Meanwhile, on the outskirts of Falluja, a network of tunnels apparently built by IS has been uncovered.
Reged Ahmad reports.
