A powerful bloc in Iraq’s parliament is calling for the withdrawal of U.S. troops from Iraq following a series of airstrikes blamed on Israel targeting Iran-backed Shiite militias in the country.

The Fatah Coalition said on Monday it holds the United States fully responsible for this Israeli aggression, “which we consider to be a declaration of war on Iraq and its people.”

The coalition is a parliament bloc representing Iran-backed paramilitary militias known as the Popular Mobilization Forces.
