The spokesman said the government was aware of reports that more than 100 Australians had engaged in the conflict since 2011 but he had "no evidence" of any citizens currently involved.

A senior Sunni politician on Thursday blamed Iraq's anti-terror forces, which report directly to Prime Minister Nuri al-Maliki's office, for the shooting of his young nephew the previous day.

Iraqi authorities on Thursday ordered the release of 11 female detainees facing criminal charges and vowed to transfer women prisoners to jails in their home provinces, in a move that addresses one of the main demands of a wave of protests by the country's Sunni minority against the Shiite-led government.

The demonstrations erupted nearly two weeks ago following the arrest of bodyguards assigned to Finance Minister Rafia al-Issawi, one of the central government's most senior Sunni officials. The protests, however, tap into deeper Sunni grievances of perceived discrimination by Shiite Prime Minister Nouri al-Maliki's government.
