Iraqi foreign minister calls for global support against Islamic State

BAGHDAD (Reuters) - Iraqi Foreign Minister Hoshiyar Zebari urged the world on Wednesday to back his country against Islamic State militants after the al Qaeda offshoot released a video purportedly showing the beheading of a U.S. journalist kidnapped in Syria. Zebari told Reuters that Islamic State was a threat to the world, not just to Iraq's minority ethnic groups whose members it has killed in its latest sweep through the north.
