As David noted below, the Islamic State has reportedly seized control of a key government complex in Ramadi, the capital of Iraq’s Anbar province, raising a flag over the city. A brief summary of the attack from Long War Journal:

The Islamic State opened its attack by using armored bulldozers to remove concrete barriers that blocked the road to the government center, according to Al Jazeera. Suicide bombers then targeted the entrance to the government compound, a military Humvee, and the Health Ministry. Three more suicide bombers targeted the Anbar Operations Command on the northwestern edge of the city. The suicide bombings were reportedly led by a British suicide bomber known as “Abu Musa Britani.”
Jihadists then stormed the breach and battled with Iraqi forces before taking control of the complex and raising the Islamic State flag over one of the buildings. . . .
The Islamic State advanced on the government center despite Coalition air support. US Central Command, which manages Operation Inherent Resolve, the mission to “degrade and defeat” the Islamist group, launched two airstrikes near Ramadi that targeted an Islamic State “tactical unit” and a “fighting position” over the past 24 hours.
