Britain is close to identifying a suspected British national shown beheading American journalist James Foley in a video released by Islamic State militants last week, the British ambassador to the United States said on Sunday.
With Islamic State fighters now in control of vast areas of northern Iraq, the country's prime minister-designate, Haider al-Abadi, used a meeting with the visiting Iranian foreign minister to call for greater international efforts to destroy the Islamist group.
Foreign Minister Mohammad Javad Zarif of Iran, a Shiite Muslim power likely to wield influence over the formation of Abadi's new Cabinet, reaffirmed Tehran's support for Iraq's territorial unity and its fight against militants.
