The Iraqi government has announced that ground forces have begun an operation to retake Tal Afar, one of the last cities in the country still held by the Islamic State group. In a televised speech announcing the offensive overnight, Prime Minister Haider al-Abadi said the jihadists had the choice between "surrender or die".
