Report: Afghan Taliban 'resilient'

WASHINGTON (CNN) - Nearly seven years after their defeat by U.S. forces, the Taliban have regrouped and have formed a "resilient insurgency," according a new Pentagon report on security in Afghanistan.

"The Report Toward Security and Stability in Afghanistan," the first-ever progress report to Congress, says that while there has been some progress in battling the Taliban, setbacks are expected.

While NATO and Afghan force operations kept the insurgency down in 2007 by killing or capturing key leaders and clearing out Taliban safe havens, the report predicted the Taliban would be back in 2008. "The Taliban is likely to maintain or even increase the scope and pace of its terrorist attacks and bombings in 2008," the report said.

The report looks at the progress through April, before the rise in violence seen over recent weeks.
