The Taliban have not attacked withdrawing U.S. forces in Afghanistan, the Pentagon confirmed Tuesday, with U.S. Central Command saying up to 20% of the American withdrawal is now complete.

Since President Joe Biden’s April 14 announcement that he would withdraw the remaining 3,000 U.S. forces from Afghanistan by Sept. 11, the Defense Department has removed the equivalent of 115 C-17 loads of material and turned over 5,000 pieces of equipment for destruction. Five facilities in all have now been turned over to the Afghan Ministry of Defense.
