Iran-backed Kataib Hezbollah has long targeted U.S. forces

The Iranian-backed Iraqi militia targeted by U.S. airstrikes on Sunday was among the Shiite groups that joined in the fight against Islamic State. But for nearly two decades it has also attacked American forces and helped stoke sectarian strife in the Middle East.

One of the most secretive and influential Shiite militias in Iraq, Kataib Hezbollah has close ties with the Quds Force, Iran’s Revolutionary Guard unit for international operations.
