Iran emerged as a major power broker in Iraq after the American invasion in 2003, supporting Shiite Islamist parties and militias that have dominated the country ever since.

The United States and its ally, Israel, are targeting pro-Iranian militias across Lebanon, Syria and Iraq with economic sanctions and airstrikes hitting their bases and other infrastructure.
