US 'regret' at fatal Iraqi coalition strike
An air strike by the US-led coalition during an offensive against the so-called Islamic State killed nine Iraqi soldiers, including an officer, Iraq's defence ministry has confirmed.
Coalition strikes were called in to support an advance by ground troops near Fallujah on Friday but failed to note the scale of their advance.
US Defence Secretary Ash Carter said he had called Iraq's prime minister to express his condolences.
