(Kabul) -- The final U.S. troops have left Afghanistan.
The remaining troops left Kabul, ending America's longest war that ran for nearly 20 years. The Pentagon promised to help Americans who may not be able to get out of Afghanistan after troops are gone.
In the final days of the chaotic pullout, 13 U.S. service members were killed in an ISIS-K suicide bombing attack near the Kabul Airport. That was followed by U.S. airstrikes against ISIS-K targets in Afghanistan.
More than 122-thousand people have been evacuated from Afghanistan in the last month.
