The top U.S. military commander in Afghanistan says Taleban insurgents could stage a high-profile attack over the next six to nine months, despite what he called their more limited "terrorist capabilities."

Lieutenant General David Barno told reporters Saturday the Taleban fighters are becoming more desperate to "change the course of events in Afghanistan."

General Barno said he expects a small hard-core remnant of the Taleban to continue fighting even as the group's military strength fades away.

Afghanistan is scheduled to hold parliamentary elections on September 18, a little less than one year after the country's first direct and democratic presidential elections.
