The White House acknowledged Tuesday that the Taliban had amassed a significant amount of U.S. military equipment after its takeover of Afghanistan following two decades of war with American forces.

Pictures and videos have shown the Taliban with firearms and vehicles that Pentagon troops used or provided to the Afghan national security forces, as well as advanced UH-60 Black Hawk attack helicopters and other equipment at the Kandahar airport.

"We don't have a complete picture, obviously, of where every article of defense materials has gone. But certainly, a fair amount of it has fallen into the hands of the Taliban," said White House National Security Advisor Jake Sullivan.
