This is indeed a major victory, as Ramadi is a key city.
“Iraqi army declares first major victory over Islamic State in Ramadi,” by Ahmed Rasheed and Maher Chmaytelli, Reuters, December 27, 2015:
BAGHDAD (Reuters) – Iraq’s army declared victory over Islamic State fighters in a provincial capital west of Baghdad on Sunday, the first major triumph for the U.S.-trained force since it collapsed in the face of an assault by the militants 18 months ago.
The capture of Ramadi, capital of mainly Sunni-Muslim Anbar province in the Euphrates River valley west of the capital, deprives Islamic State militants of their biggest prize of 2015. The fighters seized it in May after government troops fled in a defeat which prompted Washington to take a hard look at strategy in its ongoing air war against the militants.
After encircling the city for weeks, the Iraqi military launched a campaign to retake it last week, and made a final push to seize the central administration complex on Sunday.
“By controlling the complex this means that we have defeated them in Ramadi,” said Sabah al-Numani, a spokesman for the force leading the fight on the government side. “The next step is to clear pockets that could exist here or there in the city.”
State television broadcast footage of troops, Humvee vehicles and tanks advancing through Ramadi streets amid piles of rubble and collapsed houses. Some districts appeared to have been completely destroyed by the advance.
A U.S. defense official, speaking on condition of anonymity, said the U.S.-led campaign against Islamic State was unable to confirm at this point whether the militants had been cleared out of the government complex.
Television also showed nighttime celebrations in mainly Shi’ite cities south of Baghdad for the victory in Anbar, with people dancing in the streets and waving Iraqi flags from cars….
