Islamic State militants 'burn to death 45 in Iraq'

In a separate development on Tuesday, the influential Shia cleric Moqtada Sadr announced he was withdrawing his forces from an umbrella group of Shia militia fighting IS alongside the Iraqi army.

He cited what he called the bad behaviour of other militia within the Popular Mobilisation Forces, whom he accused of "wreaking havoc through murdering, kidnapping and violating sanctuaries".
