Earlier on Sunday, Abdul-Wahad Saadi, the Iraqi army commander heading the counter-terrorism operation in the city, said that Iraq's armed forces had "fully liberated" Fallujah. Iraqi Prime Minister Haider Abadi later raised the country' national flag near the city hospital, urging Iraqi people to celebrate the victory and pledging to liberate Mosul, which is still overrun by militants.
"The lessons to be learned from this battle show that a quick and important victory is possible thanks to our unity. If we want to determine the outcome of the battle for the liberation of Iraq this year, avoiding large losses and winning quickly, we must fight while supporting each other," Amiri said in a statement.
Fallujah, located some 42 miles west of the Iraqi capital Baghdad, is one of the largest cities in the Anbar province. The Daesh, outlawed in many countries including Russia, has been in control of the city since 2014.
The Iraqi Army and Shiite militias, backed by US airstrikes, launched the offensive to retake Fallujah on May 22.
Last week, Iraqi Prime Minister Haider Abadi declared Fallujah liberated from the Daesh, as the government forces gained control of the city center. However, media reported that fighting continued in the city.
