Kurdish forces in northern Iraq are claiming their biggest victory yet against Islamic State (IS) militants.

They say they have broken the IS siege of Mount Sinjar, where thousands of Yazidis and other displaced Iraqis have been trapped since August.

IS controls a swathe of Iraq and Syria, where it has declared a caliphate.
