Iraq militias start fightback against IS in Ramadi
The pro-government forces say they have retaken Husayba, east of Ramadi.
Ramadi - the capital of Anbar province - is only 110km (70 miles) west of Baghdad. Its fall was seen as a major embarrassment for the government.
About 500 people died in the city, and more than 40,000 - a third of the population - have fled.
