A top Taliban commander threatened a terror attack on the West that would dwarf the failed terror plots in London and Glasgow in a broadcast interview.

Taliban military commander Mansour Dadullah told ABC News that last month he supervised the dispatch of militant cells to United States, Great Britain, Canada and Germany from terror training camps in Pakistan.

"You will, God willing, be witness to more attacks," Dadullah was quoted in the ABC News report of an interview conducted four days ago.

Dadullah also spoke of how easily he and his forces are able to move freely through the rugged mountains of Pakistan's northwest border region near Afghanistan.
