A senior Iraqi commander declared that the city of Fallujah was “fully liberated” from Islamic State group militants on Sunday, after a more than monthlong military operation.

Iraqi troops have entered the northwestern al-Julan neighborhood, the last area of Fallujah to remain under IS control, the head of the counterterrorism forces in the operation, Lt. Gen. Abdul-Wahab al-Saadi, told The Associated Press.

Al-Saadi said the operation, which began in late May, “is done and the city is fully liberated.” The Iraqi army was backed by U.S.-led coalition airstrikes and paramilitary troops, mostly Shiite militias.

“From the center of al-Julan neighborhood, we congratulate the Iraqi people and the commander in chief…and declare that the Fallujah fight is over,” he told Iraqi state TV, flanked by military officers and soldiers. Some of the soldiers were shooting in the air, chanting and waving the Iraqi flag.
