Iraqi lawmakers approved a resolution Sunday calling to expel U.S. troops from the country, following an American drone attack that killed Iranian Gen. Qassem Soleimani.

Lawmakers approved a resolution asking the Iraqi government to end the agreement under which Washington sent forces to Iraq more than four years ago to help in the fight against the Islamic State terror group.

The majority of about 180 legislators present in Parliament voted in favor of the resolution. It was backed by most Shiite members of parliament, who hold a majority of seats. Many Sunni and Kurdish legislators did not show up for the session, apparently because they oppose abolishing the deal.
