Anti-terrorism troops hoisted the national flag atop the key complex in the long-contested Sunni Muslim city west of Baghdad, Brig. Gen. Yahya Rasool, Iraqi joint operations spokesman, said in a televised statement.
The capture of Ramadi, capital of mainly Sunni-Muslim Anbar province, deprives Islamic State militants of their biggest prize of 2015.
Iraqi troops who have fought their way deep into the Islamic State stronghold of Ramadi were consolidating their positions on Friday ahead of a planned final assault to capture the city.
The plan marks a deepening U.S. commitment to its nearly yearlong fight against ISIS, which has gained new ground through military victories in recent weeks.
Living under the Islamic State has its benefits for many Iraqis, although they live in a culture of fear, propaganda and totalitarianism.
“Get up and fight, you cowards!”
Republicans blamed Obama’s decision to pull troops out of Iraq after years of war.
Islamic State’s takeover of Ramadi gives Congressional hawks reason to criticize Obama’s foreign policy decisions.
The takeover appeared to be a major victory for Islamic State, which has withstood a large-scale U.S. bombing campaign and maintains strongholds in Iraq and neighboring Syria.
