US fears Shi'ite militias could worsen Iraqi sectarian fires

Iraq: The use of Shi'ite militias to try to take back the Iraqi city of Ramadi from Islamic State risks unleashing more sectarian bloodletting, current and former U.S. officials said, but Washington and Baghdad appear to have few other options.

The prospect of Iranian-backed militias leading efforts to retake Ramadi underlines Washington’s dwindling options to defeat Islamic State in Iraq, with Prime Minister Haider al-Abadi’s grip on power weak, a national army still in its infancy and Tehran increasingly assertive.
