BAGHDAD (AP) — Iraqi lawmakers approved Prime Minister Haider al-Abadi’s remaining Cabinet nominees on Saturday, including for the critical defense and interior portfolios, completing the formation of a government that will strive to push the Islamic State extremist group out of the sprawling territory it has seized in recent months.

Control over the two powerful security ministries has long been a source of tension among Iraq’s feuding political factions. The U.S. and other allies have been pushing for a more representative government that can reach out to Sunnis, who felt marginalized by former Iraqi Prime Minister Nouri al-Maliki. Sunni discontent is widely seen as having fueled the IS group’s dramatic advances in Iraq since June, when it captured the country’s second largest city Mosul.
