Iraqi forces 'retake Islamic State Ramadi stronghold'

The complex was "under complete control" and there was no sign of IS fighters, a spokesman said.

He said this heralded the defeat of IS in the city, although he admitted there could be pockets of resistance.

The government has been trying to retake Ramadi for weeks.

The mainly Sunni Arab city, about 55 miles (90km) west of Baghdad, fell to IS in May, and was seen as an embarrassing defeat for the army.

Tough fighting

In recent days, troops have been picking their way through booby-trapped streets and buildings as they pushed towards the city centre, seizing several districts on the way.

After sniper fire from the compound stopped and aerial surveillance detected no human activity, Iraqi soldiers moved in.

The military spokesman, Sabah al-Numani, told Reuters: "The complex is under our complete control, there is no presence whatsoever of [IS] fighters in the complex.

"By controlling the complex this means that they have been defeated in Ramadi. The next step is to clear pockets that could exist here or there in the city."

There had been no clear indications of the number of IS militants who had been defending the city, although some reports put it at around 400. No official toll of Iraqi army casualties has been given.

The Iraqi military believes the remaining militants have headed north-east; with fighting also reported to be under way to the south-west of the compound.

Gen Ismail al-Mahlawi, head of Anbar military operations, told Associated Press that the fighting had been tough given IS's use of suicide bombers, snipers and booby traps.

Concern also remains for the plight of hundreds of families who have been trapped on the frontline, the BBC's Thomas Fessy reports from Baghdad.

Although the full extent of the situation on the ground remains unclear, Agence France-Presse reported there had been celebrations on the streets of a number of Iraqi cities.

The operation to recapture Ramadi began in early November, but made slow progress, mainly because the government chose not to use the powerful Shia-dominated paramilitary force that helped it regain the northern city of Tikrit, to avoid increasing sectarian tensions.
