The Islamic State militants was said to have overran Ramadi and hoisted their black flag over local government headquarter in Ramadi city on friday.
They claimed victory through mosque loudspeakers after overrunning most of the western provincial capital.
And if indeed Ramadi were to fall,it would be the first major city seized by the insurgents since security forces and paramilitary groups began pushing them back last year.
The insurgents attacked Ramadi overnight using six sucide car bombs to reach the city centre,where the Anbar provincial government compound is located,police source said.
Fighting however,continued in one distric of Ramadi,100km(60 miles)west of Bagdhdad,and government forces were still in control of a military command centre to the west of the city.
