The name Shiite militias are using to describe the Iraqi operation to retake Anbar province from the Islamic State group is drawing ire from the Pentagon over its sectarian tilt.
The Popular Mobilization Units have named the battle that began Tuesday in Arabic: "Labaik Ya Hussein." That means "I am here, Hussein" in English. It refers to a grandson of the Prophet Muhammad and one of the most revered figures of Shiite Islam.
That has added to the worries about the Shiite militias operating in Anbar, a predominantly Sunni province long suspicious of the Shiite-led government in Baghdad.
