The Pentagon does not plan on changing its strategy in Iraq, despite the loss of Ramadi to Daesh forces over the weekend, a US army spokesmen said on Wednesday.

Col. Pat Ryder, a US Central Command spokesman, told reporters the US remains "confident" in its strategy in Iraq, even after the loss of a major Iraqi city to the militant group.

"We're confident we have the right strategy at this time to degrade and defeat ISIL," Ryder said. "You have to look at the bigger picture and how Ramadi is one fight in the larger battle."

Asked specifically if there were plans to change the US strategy, Pentagon spokesman Col. Steven Warren said flatly, "none."

Asked whether that meant "stay the course," Warren nodded and repeated the phrase.

"I think our record speaks for itself," Ryder said of the use of air power in Iraq.
