Following several months of fighting, Iraqi forces, supported by a U.S.-led airstrikes, drove Islamic State fighters out of the center of Ramadi, military officials said Monday. Ramadi is the provincial capital of Anbar province. It fell to ISIS in May.

In an interview Sunday on CNN’s “State of the Union,” Defense Secretary Ash Carter said that the Iraqi military lacked the “will to fight” the resurgent Islamic State, demonstrated by the loss of Ramadi to militant forces last week.

The New York Times reports that the city of Ramadi, capital of Iraq’s Anbar province, has fallen to the Islamic State. Security officials and tribal leaders say that the militant group has seized a large store of abandoned weapons and begun executing people loyal to the government.
