A timeline of 20 years of war in Afghanistan

We look at the timeline of Afghanistan's fall to the Taliban, and recap the US’ withdrawal from the country after 20 years of war. Now that the US military has fully withdrawn from Afghanistan, many Afghans who wanted to leave did not manage to get on an evacuation flight. We hear from one woman working for a high-profile women’s empowerment project who was left behind. Plus, Alex Rocha, a tour guide in Cartagena, Colombia, gives his customers more than just a history lesson — he shines a spotlight on Black history.
