Iraq grapples with Iranian influence ahead of May elections

Iran's influence is looming large as Iraqis prepare to head to the polls for parliamentary elections in May, with many in the country worried that Tehran may be looking to strengthen its political grip on Baghdad through the ballot box.

Iranian support and military advisers helped Baghdad's Shiite-led government beat back the Islamic State group. But with IS militants now largely defeated militarily, Iran's expanding influence has emerged as one of Iraq's most divisive issues ahead of the balloting.

That influence has sown fear among Iraq's disenchanted minority Sunnis, who bore the brunt of the war's destruction, and has also caused concern in Washington. Despite tensions between the United States and Iran, both remain key allies of Iraqi Prime Minister Haider al-Abadi's government.
