British intelligence officials fear large-scale terrorist attacks against the West in the wake of the Taliban ’s return to power in Kabul, and one U.S. lawmaker described Afghanistan as an emerging "terror super-state."

The grim forecast came as the United States prepares to mark the 20th anniversary of 9/11 with the terrorist government back in control of the lawless country from which the attack was launched.
