Umm al-Waz

Iraqi forces have launched an offensive to recapture the last bastion of so-called Islamic State in the country.

Soldiers, police, Sunni tribesmen and mostly Shia paramilitary fighters are taking part in the assault on al-Qaim and Rawa, in the Euphrates river valley close to the border with Syria.

The prime minister told IS militants to "choose between death and surrender".
