Two U.S. officials said on Friday that nearly 20 years later, the U.S. military left Bagram Airport, the center of its war, aimed at expelling the Taliban and hunting down the al-Qaeda perpetrators who attacked the United States on September 11.

The airport has all been handed over to the Afghan National Security and Defense Forces, and they stated that their identities are unknown because they have no right to release it to the media.

One of the officials also stated that General Austin S. Miller, the top U.S. commander in Afghanistan, “still retains all the capabilities and powers to protect the force.”
