US defence secretary questions Iraq's 'will to fight' after Ramadi defeat

The Daesh group's takeover of Ramadi is evidence that Iraqi forces do not have the "will to fight," US Defense Secretary Ash Carter said on Sunday.

Iraqi forces outnumbered their opposition in the capital of Anbar province, but failed to fight and pulled back from the city in central Iraq, Carter said on CNN's State of the Union.

The Iraqis left behind large numbers of U.S.-supplied vehicles, including several tanks.

"What apparently happened is the Iraqi forces just showed no will to fight. They were not outnumbered," Carter said of the Iraqi forces. "In fact, they vastly outnumbered the opposing force. That says to me, and I think to most of us, that we have an issue with the will of the Iraqis to fight Deash and defend themselves."

The fall of Ramadi last Sunday has sparked questions about the effectiveness of the Obama administration's approach in Iraq, a blend of retraining and rebuilding the Iraqi army, prodding Baghdad to reconcile with the nation's Sunnis and bombing Islamic State group targets from the air without committing American ground combat troops.

Carter defended the use of U.S. airstrikes as an effective part of the fight against the Islamic State group but said they are not a replacement for Iraqi forces willing to defend their country.
