Washington (AFP) - US Defense Secretary Chuck Hagel warned Thursday that the Islamic State is more than a traditional "terrorist group" and better armed, trained and funded than any recent threat.

"They marry ideology and a sophistication of strategic and tactical military prowess. They are tremendously well funded. This is beyond anything we have seen," Hagel told reporters.
