Qaeda's leader in Iraq threatened military action in a bid to prevent a parliamentary election being held next month, as official campaigning started in the country Friday. Abu Omar Al-Baghdadi warned in an audiotape that his Al-Qaeda front, the Islamic State of Iraq, had “decided to prevent the elections by all legitimate means possible, primarily by military means,” US monitors SITE said.

One hundred and forty-five appeals were rejected, he said. Other candidates had been voluntarily replaced by their parties.“Among those whose appeals were rejected were Saleh al-Mutlaq and Dhafer al
