(AP) — Afghans have rushed onto the tarmac of the capital’s airport, as thousands try to flee the country after the Taliban seized power. Some clung to the side of a U.S. military transport plane before takeoff Monday. The widely shared image captured the sense of desperation as America’s 20-year war comes to a chaotic end. The Taliban swept into Kabul on Sunday after President Ashraf Ghani fled the country. That brought an end to a two-decade campaign in which the U.S. and its allies had tried to transform Afghanistan. In the capital, a tense calm set in Monday, with most people hiding in their homes. Many fear chaos or a return to the kind of brutal rule the Taliban imposed when they were last in power.
