A senior Iraqi commander has declared the city of Fallujah "fully liberated" from Islamic State group militants after a more than monthlong military operation.

The head of the counterterrorism forces in the operation, Lt. Gen. Abdul-Wahad al-Saadi, told The Associated Press that on Sunday his troops entered the northwestern al-Julan neighborhood, which was the last area still under IS control.

Al-Saadi says the operation, which began late May, "is done and the city is fully liberated."

Fallujah has been under the control of Islamic State militants since January 2014.
